Richardson RFPD Introduces DFE Series Of Metal Alloy Inductors From TOKO

Richardson RFPD

Ideal for today’s efficient DC/DC converters

Richardson RFPD, Inc. announced recently the availability and full design support capabilities for select parts from the DFE series of metal alloy inductors from TOKO.

The DFE series metal alloy inductors are based on a proprietary process that offers high current handling

capability in an extremely small footprint. Soft saturation characteristics and the ability to handle higher switching frequencies make these devices an ideal choice for today’s efficient DC/DC converters.

According to TOKO, key features of these select parts from the DFE series include:
