A low loss MnZn ferrite material for power applications up to 200 kHz.

New type of 98 material is an improved version of Fair-Rite’s 78 material. This material supplies lower power loss at 100°C at moderate flux densities for operation below 200 kHz.

Available in 98 material:

E&I Cores

Pot Cores

RM

PQ

ETD

EFD

EP

EER
