Type RA Radial PET Film Capacitors
The RA style capacitor is constructed in an efficient rugged self-
encased size. The non-inductive multilayer metallized polyester film
capacitor features a small size, high dv/dt capability, very low ESR
at high frequency and a self-healing capability. RA type capacitors
are ideal for use in high frequency switching power supplies, noise
suppression, EMI reduction and long-life applications.
Highlights
- Efficient size
- Self healing
- Low ESR/ESL
- High dv/dt
