These devices use an aluminum anode and organic electrolyte system to provide reliable and responsive capacitance, while providing high life performance. Many of these applications require high current pulses or rapid voltage changes, making the SEK470M025ST an ideal choice for robust power control.

Working Principle

The SEK470M025ST works on the principle of electrolytic shell chemistry. When an electric current passes through the electrode-electrolyte system, a reaction occurs that creates a layer of aluminum oxide on the anode. This oxide layer provides the capacitance required for the circuit. The electrolyte provides an ionically conductive path between the anode and cathode, which in turn provides the stability and effective capacitance needed for operation.

The SEK470M025ST is a low-profile, low-cost capacitor solution with a construction that makes it highly resistant to high vibration, wide temperature range, and rapid voltage transients. It also features a long life span up to 2000 hours at rated voltage, making it a reliable power supply component in high-reliability applications.

The SEK470M025ST is designed to provide reliable, cost-effective performance in high-reliability automotive, telecommunications, and industrial power control applications. With its low-profile, cost-effective design, high life performance, and wide temperature range, the SEK470M025ST is well suited for a variety of power electronic applications.
