Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors are widely used in power electronics, automotive and industrial applications due to their high capacitance and long life. This type of capacitors consists of two aluminum foils as electrodes, which are separated by an electrolytic solution-filled paper spacer and enclose an anodized aluminum can as a housing. They are typically identified by their manufacturer, name, series, capacitance, rated voltage, capacitance tolerance, and temperature range.

The B41821A7688M000 is a series of aluminum electrolytic capacitor from EPCOS. It is a radial leaded type aluminum electrolytic capacitor and features a capacitance range from 68uF to 8200uF, rated voltage from 16V to 160V and capacitance tolerance of ± 20%. The temperature range is from -40°C to +105°C with load life of 2000 to 3000 hours.

The B41821A7688M000 capacitor has several applications. It is used in power supplies and DC to DC power converters, DC to AC inverters and UPSs, and motor control circuits. It is also suitable for line filters, power factor correction circuits, surge suppressors, and energy storage and motor drive in LED lighting applications. The B41821A7688M000 capacitor can also be used in power factor correction and input smoothing circuits.

The major working principle of aluminum electrolytic capacitors is that the two aluminum foils act as the electrodes and store electrostatic energy when a voltage is applied across its terminals. When a current flows through the capacitor, the anode electrons move to the cathode and a charge is stored in the electrolytic solution between them. This charge creates a voltage drop in the circuit, which causes the current to reduce. This reduction in current allows the voltage to be maintained at its rated level. This process results in a capacitance that can store and release energy.

In conclusion, the B41821A7688M000 aluminum electrolytic capacitor is a radial leaded type capacitor with high capacitance and long life. It has a wide range of applications in power electronics, automotive and industrial applications. It functions by the electrostatic energy stored by two aluminum electrodes and electrical energy stored in the electrolytic solution between them. This process ensures that the voltage can be maintained at its rated levels.
