CBB81 High Voltage Inverters

structure consists of aluminum foil electrodes, electrolyte, and electrolytic paper, etc. The aluminum foil undergoes electrochemical corrosion to form a porous structure, increasing the surface area and enhancing the capacitance capacity.

This type of capacitor is a polar capacitor. In the circuit, it must be correctly connected according to the positive and negative polarities; otherwise, it may cause the electrolyte to decompose, heat up, and even lead to leakage or explosion due to reverse voltage. Its capacity is usually large, ranging from a few microfarads to several thousand microfarads. It is suitable for scenarios where a large amount of electrical energy needs to be stored. For example, in power supply filter circuits, it can effectively absorb AC ripple in the power grid, making the output DC voltage more stable. In the power amplifier circuit of audio equipment, it can assist in providing a large instantaneous current to ensure the stable output of sound signals.

The performance of red aluminum foil capacitors is significantly affected by temperature. Generally, their operating temperature range is around -40 ℃ to + 105℃. Long-term use in high-temperature environments will shorten their service life. Compared with ceramic capacitors such as MLCC, it is relatively larger in size and has slightly inferior frequency characteristics, but it has irreplaceable advantages in low-frequency circuits and applications that require large-capacity energy storage.
