FFVS series is a specific range of DC filtering capacitors

designed for use in high frequency, high ripple applications

beyond the limits of standard FFVE or FFVI.

Typical applications include DC power supply for induction

heating, resonant DC power supply for scanner, X-ray

machines, etc.

Due to the sophisticated internal design, stray inductance is

extremely low, between 8 and 13nH.

FFVS products are RoHs compliant.

PACKAGING MATERIAL

Self extinguishing plastic case (V0: in accordance with UL 94)

δ0 (tan delta)

For polypropylene, tg

δ0 = 2 x 10-4 for frequencies

up to 1MHz and is independent of temperatures.

For polyester, tg

δ0 values are shown in graph 4
