It has an extended temperature range of -40℃ to +125℃ and a maximum ripple current/maximum ripple voltage of 15mA/1.5V. The aluminum electrolytic capacitor has an insulation resistance of 20M at 500V DC, and a maximum leakage current of 0.03 CV or 3mA, whichever is lower.

Working Principle

Aluminum electrolytic capacitors are capacitors that use an electrolyte article to form two electrodes. The separator used in the aluminum electrolytic capacitor is paper impregnated with an electrolyte, such as hydrochloric acid or ammonium hydroxide, which should not be in contact with each other. The electrolyte behaves as the dielectric, providing the large capacitance with a relatively thin structure. The aluminum foil in the electrolytic capacitor acts as the anode. The oxide layer on the aluminum foil surface acts as the dielectric, so the oxide layer must not be damaged during the production process. The cathode is the metallic contact on the bottom of the electrolytic capacitor.

The LXZ63VB12RM5X11LL series is a radial aluminum electrolytic capacitor, which means the anode and cathode are marked on the top edge and bottom edge, respectively. The top of the capacitor has an anode marked with a negative sign on the surface, while the bottom has a cathode lead marked with a positive sign. When the capacitor is in operation, the anode pole is negative and the cathode pole is positive. Current passes through the electrolyte and the oxide layer to form a capacitance, allowing the capacitor to store energy.
