Capacitor is an indispensable part of many circuits and power equipment. Due to the different requirements in the circuit, different capacitors are needed, so capacitors can be divided into many different types. It can be divided according to many factors such as structure, material and function. MKP is one of them. What are the functions and characteristics of MKP capacitance? You might as well follow the professionals to learn about it.

MKP is the abbreviation of metallized polypropylene film capacitor, which represents the material of capacitor. Metallized polypropylene capacitor, small loss of lead out, small internal temperature rise, negative capacitance temperature coefficient, excellent flame retardant performance.

It is widely used in high-voltage and high-frequency pulse circuit, S-correction and line reverse stroke waveform in TV and display, electronic rectification absorption and SCR rectification circuit in lighting circuit. For safety regulation. It's also useful when RC depressurizes,

In addition, the metallized capacitor is made of polypropylene as the medium, and aluminum is deposited on the film by vacuum evaporation method. It is wrapped with insulating material and unidirectionally led out. It has excellent electrical performance and is suitable for DC and pulse circuits of electronic equipment.

There are many functions and characteristics of MKP capacitance. Let's talk about the characteristics of this kind of capacitor.

MKP capacitor adopts fully sealed rectangular metal shell with fixed plate at the bottom or both sides and ceramic insulator. And take a non inductive winding method, so the cylindrical metal aluminum shell, small volume, light weight. Relatively speaking, it has good electrical performance, small loss and good self-healing.

Not only that, the pressure explosion-proof device is installed inside, which is safe and reliable. It is usually used in AC power system, especially for special capacitor of air conditioner compressor and assembling power factor automatic compensation cabinet.

How much capacitance is the best for midrange speakers

——The selection of capacitor has a great influence on the sound playing of the midrange loudspeaker. It is not suitable to be too large or too small.

——In general, the capacitance of about 10 μF can be selected according to the law.

There are two choices of capacitors for midrange speakers:

1. Nonpolar capacitor with 4.7uF

2 connect two 10uF capacitor positive electrodes in series

If the mid tone loudness is low, increasing the capacitor's capacitance will only change the frequency division point, but not the loudness. In addition, blindly increasing the capacitance will increase the current of the midrange speaker (medium and low frequency current), which may burn out the midrange speaker when rated output!

Which sound quality is better with solid state electrolytic capacitor or audio capacitor?

There are various kinds of audio capacitors because of their different uses, different structures and different materials. Their electrical properties, structures and uses depend largely on the medium used. According to the media, they are classified into organic medium, inorganic medium, liquid oil medium and gas dielectric capacitor, etc. in terms of audio circuit, the most commonly used transistors are organic medium and inorganic dielectric electrolytic capacitor .Organic dielectric capacitance, also known as film capacitance, is mainly composed of paper dielectric (MP), metal dielectric, polyester (Mylar, also known as polyester), polystyrene (MKS), polypropylene (MKP), polycarbonate (MKC) and Polyterephthalate (MKT).

Among them, paper dielectric, polyester, polypropylene three kinds of capacitors are respectively divided into metallized medium and non metallized medium. Generally speaking, once the capacitor of metallized medium is broken down, the arc generated at the breakdown point will melt and evaporate the metal film and eliminate the short circuit. It can automatically resume normal operation and have self-healing function. The performance of this kind of capacitor is very good, which is generally used in power supply. Metallized polyester capacitor (Mylar) and metallized polypropylene capacitor (MKP) can eliminate the inductance caused by winding, and make a better performance non inductive capacitor. This kind of capacitor should choose the nominal capacitance on the capacitor, and the winding process is special, so the non inductive capacitor can be made. The inorganic capacitors are mainly mica, ceramic dielectric, single stone and glass glaze.

Electrolytic capacitor is represented by aluminum electrolytic capacitor, which has the characteristics of small volume and large capacity. It can achieve dozens of micro methods to 20000 or 30000 micro methods, but its impedance frequency characteristics are poor, temperature characteristics are not good, low insulation resistance, large leakage current, long time not used will deteriorate and fail. Because the conductivity of electrolyte is not very good, the resistance is large, the loss is also large, the distributed capacitance and error are not very small, so the performance of electrolytic capacitor is far inferior to that of thin film capacitor. It is only suitable for power filter and power decoupling, not suitable for audio frequency coupling circuit.

What is the best for your speaker and crossover applications MKP or MKT capacitors?

1. MKP: MKP has high withstand voltage starting point, small lead out loss, small internal temperature rise, negative capacity temperature coefficient, excellent flame retardant performance. It is used in high voltage and high frequency pulse circuit, S-correction and reverse stroke waveform in TV and display, electronic rectifying absorption and SCR rectifying circuit in lighting circuit.

2. MKT: non polarity, high insulation impedance, excellent frequency characteristics (wide frequency response), and small dielectric loss. Thin film capacitors are widely used in analog circuits. Especially in the part of signal cross connection, it is necessary to use capacitors with good frequency characteristics and very low dielectric loss, so as to ensure that the signal will not have too much distortion during transmission.

It can be seen from the above that the frequency characteristics of MKP should be better than that of MKT. All film capacitors are enough for audio coupling, and high-frequency electrolysis of industrial products is not bad, but capacitors are the components that have the greatest impact on timbre. Replacing a pair of coupling capacitors is enough to change the sound trend of the whole machine. MKT is called polyester capacitor in China, Because of its low price and good high-frequency characteristics, many domestic machines are used, and the timbre is bright, hard and dry. Compared with MKT, the timbre of MKP is soft, transparent and delicate. Its listening feeling is similar to that of some audio special electrolysis. BP audio electrolysis is more used in coupling, and MKP is only used in small capacity occasions.

Conclusion: WEET WMF MKP Precise Audio Capacitor 6.8uF +/-5% 250VDC is the bet alternative for your speaker and crossover applications.

Is the MET capacitor on audio frequency divider the same as MKP capacitor ?
The answer is No, the two capacitors use different media dielectric

MET: Metallized polyester film axial capacitor
MKP: Metallized polypropylene film axial capacitor

MKP is usually used for treble, and MKP is better than MET, especially for high frequency signal (treble). 
MET is not so good, but in order to reduce the cost, it will be used, and it has no obvious effect on bass applications.

Can capacitors with different capacities and the same voltage be used in parallel

https://www.dummies.com/programming/electronics/components/electronics-components-capacitors-in-parallel-and-series/

Can Combine capacitors in parallel?

Calculating the total capacitance of two or more capacitors in parallel is simple: Just add up the individual capacitor values to get the total capacitance.

This rule makes sense if you think about it for a moment. When you connect capacitors in parallel, you’re essentially connecting the plates of the individual capacitors. So connecting two identical capacitors in parallel essentially doubles the size of the plates, which effectively doubles the capacitance.

Remember: Whenever you see two or more capacitors in parallel in a circuit, you can substitute a single capacitor whose value is the sum of the individual capacitors. Similarly, any time you see a single capacitor in a circuit, you can substitute two or more capacitors in parallel as long as their values add up to the original value.

Tips: The total capacitance of capacitors in parallel is always greater than the capacitance of any of the individual capacitors. That’s because each capacitor adds its own capacitance to the total.

Summary: We do not suggest to combine capacitors, as the more capacitors you combine,  the bigger total capacitance you will get. Usually you have to choose the single right capacitance capacitor for your application.

400V 3.3uF frequency divider audio MKP Non polarized frequency dividing capacitor, also called as new audiophiler MKP red film kondensotor 400V 3.3uF film capacitor, axial lead.

Can WEET WMF Precise Audio Cap. 250V 3.3uF capacitor be replaced by 400V 3.3uF Capacitor?

Yes, the principle is that the withstand voltage must be the same as or higher than your original one, and the capacity is the same, but don't be too big. If it is too large, it will be wasted. Because the higher the withstand voltage is, the larger the capacity is, the more expensive the capacitor will be!

If the 250V 3.3uF  capacitor is broken, whether it can be replaced by  400V 3.3uF depends on the starting function of the capacitor in the circuit. 
The general power supply line is OK, but it can't be used as the motor starting capacitor.
