The FFVS series is a range of DC filtering capacitors available from AVX Corporation that are used everywhere standard FFVE or FFVI capacitors cannot accommodate the high frequency ripple current in certain applications. Examples include DC power supplies for induction heating and resonant DC power supplies for scanners, X-ray machines, and much more.

Due to the sophisticated internal design of these capacitors, stray inductance is extremely low, between 8 nH and 13 nH.
