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

Speciﬁcations

- Wave solderable

Bold P.N.: -55° to +125°C

ꢁderate voltage 1.ꢂ±ꢀ / °C above +8±°C)

Apply 1.ꢂ± x the rated DC voltage for 1000 hours at +8±°C.

After the test, the capacitance, DF, and IR should meet the following:

Capacitance change: ≤ ±.0ꢀ

Life Test:

DF will meet the initial speciﬁcation

Insulation Resistance will meet the initial speciﬁcation

Subject the capacitor to +8±°C / 8±ꢀ RH for ꢂ1 days without voltage.

After the test, the capacitance, DF, and IR should meet the following:

Capacitance change: ≤ 7.0ꢀ

Moisture Test:

DF will meet the initial speciﬁcation

Insulation Resistance ≥ 30ꢀ of the initial limit

After ꢂ years of storage in a standard environment.

Capacitance change: ≤ꢂ.0ꢀ
