Working Principle of B43601E2277M62

The aluminum electrolyte used in B43601E2277M62 is generally made of aluminum foil and organic electrolyte. The anode foil of the electrolytic capacitor is usually rolled and compounded, and a large number of longitudinal distribution layers of anode foil add capacitance to the capacitor, improve withstand voltage and lower ESR. The negative electrode of B43601E2277M62 comprises a lead wire and a conductive media, which connects the positive and negative poles of the capacitor, controls the distribution of electric charge during operation, and facilitates the flow of electric current.

The organic electrolyte is the core of the aluminum electrolytic capacitor, which is usually an aqueous solution containing anhydrous aluminum oxide, metal salt, etc. It provides a medium for electric charge conduction and reaction, which is the part that directly affects the aging process of the aluminum electrolytic capacitor. The purpose of B43601E2277M62 organic electrolyte reformulation is to improve the electrolyte absorption and compatibility, enhance the insulation performance, anti-leakage performance and anti-humidity performance, and extend the service life of the capacitor.

The working principle of B43601E2277M62 is the same as that of general aluminum electrolytic capacitors. It relies on strong dielectric material strips to ensure the required insulation voltage. Generally, when the voltage is lower than its rated voltage, the internal electrolyte of the capacitor is in a highly ionized state. Under this condition, the capacitor can maintain its rated capacitance. When the voltage is higher than the rated voltage, the insulation performance will decrease, and the capacitance will also decrease.

In addition, B43601E2277M62 aluminum electrolytic capacitors also have temperature characteristics, the temperature coefficient is generally equal to -15ppm/°C. That is, as the temperature rises, the capacitance decreases with a rate of -15 ppm/°C. They are also sensitive to frequency and temperature, the performance will be affected by changes in frequency and temperature. The withstand voltage also decreases with the frequency, so the operating voltage should not exceed 70%~90% of its rated voltage.

Conclusion

To sum up, B43601E2277M62 belongs to low impedance aluminum electrolytic capacitors. Its application fields include power, audio and communications. The working principle of B43601E2277M62 aluminum electrolytic capacitors is based on strong dielectric material strips to ensure the required insulation voltage. The temperature coefficient is generally equal to -15ppm/°C. In addition, they are sensitive to frequency and temperature, so the operating voltage should not exceed 70%~90% of its rated voltage. Therefore, engineers and designers need to select capacitors according to different application sites and conditions.
