Its combination of high-temperature performance, extended life, and wide operating voltage range makes it ideal for high-end applications such as aerospace and military applications.

The working principle of the EMVA500GDA471MLH0S is based on the same principles that apply to traditional aluminum electrolytic capacitors. The capacitor works by collecting and storing electrical energy. An electrode on the capacitor – called the anode – collects electrons from a circuit and stores them within a dielectric material. When a voltage is applied to the capacitor, the electrons are discharged due to the opposing voltage and they flow through the circuit to be used as necessary.

The EMVA500GDA471MLH0S is a versatile, reliable, and high-performance aluminum electrolytic capacitor, ideal for extreme temperature and harsh environment applications. Designed for applications where high capacitance, extreme temperature performance, and extended life are important, the EMVA500GDA471MLH0S is the perfect choice for mission-critical applications.
