Additional Details

The PHE820 series capacitors are designed to withstand harsh environmental conditions, including high humidity and temperature variations. The self-healing properties of the metallized polypropylene film ensure that any localized breakdowns in the dielectric are quickly cleared, preventing catastrophic failures and extending the capacitor's lifespan. The UL 94 V-0 rated plastic case provides excellent flame retardancy, enhancing the safety of the application. These capacitors are specifically designed for AC line filtering and interference suppression, protecting sensitive electronic equipment from voltage transients and noise. The construction ensures minimal inductance and ESR (Equivalent Series Resistance), which is crucial for effective high-frequency noise filtering. The 275VAC rating allows for reliable operation in standard mains voltage applications. The epoxy resin filling contributes to the overall mechanical stability and prevents moisture ingress, further enhancing the capacitor's reliability. Its robust design and electrical characteristics make it a suitable choice for demanding industrial and consumer electronics applications where reliable interference suppression is essential.
