WEET How to Understand the of Polarity of Horizontal Axial Through Core Polar Electrolytic Capacitor

WEE Technology Company Limited - WEE are Capacitors Specialist

Aluminum electrolytic capacitor is a kind of capacitor with thin oxide film as the medium, which is made of water absorbing paper with paste electrolyte sandwiched between two aluminum foils. Because the oxide film has unidirectional conductivity, the electrolytic capacitor has polarity.
Today, WEET engineers will show you How to Understand and Test the of Polarity of Horizontal Axial Through Core Polar Electrolytic Capacitors

If the polarity of electrolytic capacitor is unknown, the polarity can be measured by the resistance block of multimeter.

We know that the leakage current of the electrolytic capacitor is small (the leakage resistance is large) only when the positive pole of the electrolytic capacitor is connected to the power supply (the black probe in the resistance block) and the negative terminal is connected to the power supply (the red probe in the resistance block). On the contrary, the leakage current of electrolytic capacitor increases (the leakage resistance decreases).

When measuring, first assume that a certain pole is "+" pole, let it connect with the black probe of the multimeter, and the other electrode connects with the red probe of the multimeter, record the scale of the stop of the probe (the resistance value of the probe to the left is large), then discharge the capacitor (i.e. two leads touch each other), and then adjust the two probes, and measure again. In the two measurements, when the last position of the probe is to the left (high resistance), the black probe is connected to the positive pole of the electrolytic capacitor.

At the same time, we also can distinguish the polarity of WEET Axial WAA Aluminum electrolytic capacitor by external appearance. Firstly, the marking arrow indicated the negative polar. Secondly, the terminal end has an obvious soldering joint and pup up, which means the negative polar.

WEET How to Distinguish Solid Polymer Electrolytic Capacitors and Liquid Electrolytic Capacitors

WEE Technology Company Limited - WEE are Capacitors Specialist

The intuitive way to distinguish WEET solid electrolytic capacitor and WEET liquid electrolytic capacitor is to check whether there is a "K" or "cross" shaped explosion-proof groove on the top of the capacitor. The top of the solid electrolytic capacitor is flat without explosion-proof groove. There is also a solid and liquid mixed type electrolytic capacitor, the explosion-proof groove on the top of which is shallow. In addition, liquid electrolytic capacitors generally have plastic skins of various colors. There are two packaging forms for electrolytic capacitor.

It is a common in-line package, which is cylindrical in shape, with two metal leads below as electrodes, installed vertically on the circuit board. Another way is to install the vertical main board with rubber base. This SMT chip type capacitor is easy to use in large-scale, high-density production, and can achieve efficient and fast welding, while occupying a small area on the main board. The main basis for distinguishing SMT chip type and direct plug-in capacitor is the plastic base at the lower end of the capacitor.

WEET Shares Advantages of Solid Polymer Electrolytic Capacitor Over Liquid Electrolytic Capacitors

WEE Technology Company Limited - WEE are Capacitors Specialist

Solid aluminum polymer chip capacitor is a unique structure which combines the characteristics of aluminum electrolytic capacitor and tantalum capacitor. Like the electrolytic capacitor of liquid aluminum, the solid aluminum polymer is mostly in the form of chip. The polymer electrode film with high conductivity is deposited on alumina as cathode, and carbon and silver as lead out electrodes, which is similar to the structure of solid tantalum electrolytic capacitor.

Due to the use of a new type of solid electrolyte, solid-state electrolytic capacitors have excellent characteristics that cannot be matched by liquid electrolytic capacitors. These electrical properties are very important for improving the application of high frequency in computer system. The advantages of solid electrolytic capacitor over liquid electrolytic capacitor are mainly three points.

1. WEET Solid aluminum electrolytic capacitor has High stability than liquid electrolytic capacitors.

Solid aluminum electrolytic capacitor can work stably in high temperature environment, and the performance of main board can be improved directly by using solid aluminum electrolytic capacitor. At the same time, it is suitable for power filter because of its stable impedance in wide temperature range. It can effectively provide stable and abundant power supply, which is particularly important in overclocking.

Solid state capacitors can still work normally in high temperature environment, and maintain various electrical properties. The change of capacitance is less than 15% in the whole temperature range, which is obviously better than the liquid electrolytic capacitance. At the same time, the capacitance of solid-state electrolytic capacitor is basically independent of its working voltage, so as to ensure its stable operation in the voltage fluctuation environment.

2. WEET Solid aluminum electrolytic capacitor has longer life than liquid electrolytic capacitors.

The solid aluminum electrolytic capacitor has a very long service life (more than 50 years). Compared with the electrolytic capacitance of liquid aluminum, it can be regarded as "longevity". It will not be broken down, and there is no need to worry about the drying of the liquid electrolyte and leakage affecting the stability of the motherboard. Due to the lack of problems of liquid electrolyte, the solid aluminum electrolytic capacitor makes the main board more stable and reliable.

The solid electrolyte will not evaporate, expand or even burn like the liquid electrolyte in the high temperature environment. Even if the temperature of the capacitor exceeds its tolerance limit, the solid electrolyte will only melt, so that the metal shell of the capacitor will not burst, so it is very safe.

The working temperature directly affects the life of the electrolytic capacitor. The life of solid electrolytic capacitor and liquid electrolytic capacitor is significantly longer under different temperature environment.

3. WEET Solid Polymer aluminum electrolytic capacitor has lower ESR and high rated ripple current than than liquid electrolytic capacitors.

ESR (equivalent series resistance) refers to the series equivalent resistance, which is a very important indicator of capacitance. The lower ESR is, the faster the capacitor charging and discharging speed is. This performance directly affects the decoupling performance of the microprocessor power supply circuit. In the high-frequency circuit, the advantage of the low ESR characteristic of the solid-state electrolytic capacitor is more obvious. It can be said that the low ESR characteristic at high frequency is the watershed of the difference between the performance of solid electrolytic capacitor and that of liquid capacitor. The ESR of solid aluminum electrolytic capacitor is very low, and the energy dissipation is very small. Under high temperature, high frequency and high power conditions, the very low ESR characteristics of the solid-state capacitor can fully absorb the high amplitude voltage generated between the power lines in the circuit and prevent its interference to the system.

At present, the power consumption of CPU is very large, and the main frequency is far beyond 1GHz. At the same time, the peak current of CPU reaches 80A or more, and the output filter capacitance is close to the critical point. On the other hand, the CPU adopts multiple working modes, most of which are in the conversion process of working mode. When the CPU changes from low power consumption state to full load state, a large amount of energy required for instantaneous (generally less than 5 ms) switching of the CPU is from the capacitance in the CPU power supply circuit. At this time, the high-speed charging and discharging characteristics of the solid-state capacitance can output peak current in an instant to ensure sufficient power supply and stable operation of the CPU.

WEET WPA SMD Miniaturized Conductive Polymer Aluminum Solid Electrolytic Capacitors Advantages:

Solid Polymer capacitor has the advantages of environmental protection, low impedance, high and low temperature stability, high ripple resistance and high reliability. It is the highest level product in the current electrolytic capacitor products. As the solid-state capacitor e is far superior to the liquid aluminum capacitor, and the solid-state capacitor has a temperature resistance of 260 degrees, good conductivity, frequency characteristics and service life.
