Filter Capacitor

Feature

High-performance structure:

Adopting metalized polypropylene film and non sensitive winding process, combined with special gold spraying and flame-retardant epoxy sealing, the structure is compact and reliable.

Excellent electrical performance:

Has low equivalent series resistance (ESR), low parasitic inductance, high ripple current resistance, and good temperature stability.

Long lifespan and high reliability:

Slow attenuation under high temperature and high ripple conditions, long service life, and support maintenance free operation.

Complete security protection:

Built in explosion-proof design, the shell is made of flame-retardant materials, effectively preventing risks such as explosion and fire
