The series designated DCL 23, have a very low equivalent series inductance (ESL). The coaxial construction can give an ESL as low as 11 nH. These features make them suitable for use at high resonant frequency 61 to 460 K Hz. The internal design uses segmented film. This ensures controlled "self healing". These capacitors can be used in induction heating equipment, resonant power supplies, high ripple current circuits to name only a few.
