WEET Hand Made Cement Ceramic Resisotrs SQM SQP and SQZ Non-Flammable and Heat Resistant Audio Grade
WEE Technology Company Limited - WEE are Capacitors Specialist
Cement ceramic resistor is a resistor sealed with refractory mud (commonly known as cement, actually not cement).
The outer side of the cement resistance is mainly made of ceramic materials (generally divided into high alumina porcelain and feldspar porcelain).
Cement Resistors Characteristic:
1. Shock resistance, moisture resistance, heat resistance, good heat dissipation, low price and other characteristics.
2. Fully insulated, suitable for printed circuit boards.
3. The wire is wound on the porcelain rod and then the joint is welded to make the accurate resistance value and prolong the service life.
4. The high resistance value is made of metal oxide film (MO) instead of winding.
5. Excellent heat resistance, low resistance temperature coefficient, linear change.
6. Resistance to short-time overload, low noise, resistance value has no change over the years.
7. Good explosion-proof performance and protection.

WEET How Much Do You Know About the Effect and Performance of Resistor on Sounding in Sound Application
1. Metal Film Resistor
It has the characteristics of low noise, high temperature resistance, small size, high stability and precision.
The disadvantage is that the price is more expensive than carbon film resistance.
2. Carbon Film Resistor
The stability is relatively high and the noise is relatively low, but in terms of quality, it is still worse than the metal film resistance, but it is cheaper than the metal film resistance.
Therefore, this kind of resistance is widely used in various electronic circuits, including the gall machine circuit.
3. Carbon Composition Resistor
It is the earliest resistor produced. Because of its poor resistance stability, high noise and temperature coefficient, it has been replaced by metal film resistance and carbon film resistance.
4. Wire Wound Resistor
It is made by winding resistance wires on a ring-shaped framework. Its stability and precision are very high.
However, due to its large size, it is generally only used in high-power places, such as the power supply circuit of a galloping machine.

1. Material introduction of MMKP82 capacitor.
MMKP82 capacitor is a kind of CBB capacitor, so its main material is also metallized polypropylene film. MMKP82 capacitor uses polypropylene film as the medium,
high-temperature resistant double-sided metallized polypropylene film with excellent self-healing characteristics as the electrode,
and the two ends are sprayed with gold to form a non inductive structure.
It is led out in one direction, and the lead out is made of tinned copper wire (Cu wire) and encapsulated with flame-retardant epoxy resin.
2. Why are MMKP82 capacitors so rare?
Generally, we use CBB81 capacitors in resonant circuits.
However, the biggest inconvenience of this type of capacitor is that it is too large, and it will take up a lot of space to install on the circuit.
Moreover, it is also a powder coated capacitor. Its high temperature resistance and high humidity performance are not good. This problem can be solved by using MMKP82 capacitors.
3. Why is it so difficult to produce MMKP82 capacitors?
The double-sided metallized polypropylene film is not easy to produce, and the manufacture of this capacitor also requires customized special winding machine equipment, which is expensive;
In addition, during the manufacturing process, the operating skills of operators are very strict, the operation efficiency is low, and the overall cost is high.
Therefore, at present, there are not many manufacturers that can produce double-sided metallized polypropylene film capacitors with plastic shells.
However, at present, there are some powerful manufacturers in China that can produce such capacitors, and their performance is much better than CBB81 capacitors.
4. What is the function and application of MMKP82 capacitor?
MMKP82 capacitor has the same function as CBB81 capacitor. At present, it is mainly used in high voltage, high frequency and pulse circuits.
For example, the performance of electric vehicle charging pile power control board, high-power LED driving power supply, mining machine power supply, ultrasonic power supply and other circuits is better than that of CBB81 capacitor.
