Planar Cores (7895400421)
Part Number: 7895400421
95 PLANAR EI CORE SET
Planar EE and EI cores, with their low profile are suitable for board level installation allowing assembly without the need for plastic coilformers and can also allow windings integrated into multi-level PCBs. Planar ER cores with their low mass and low profile are suitable for Surface Mount installations in low power filter and transformer applications.
Planar EE, ER and EI cores can be supplied with the center post gapped to a mechanical dimension, or an AL value.

AL value is measured at 1 kHz, B < 10 gauss.
A low loss MnZn ferrite material for power applications up to 200 kHz with low temperature variation. New type of 95 material is a low loss power material which features less power loss variation over temperature (25-100°C) at moderate flux densities for operation below 200 kHz.
Available in 95 material:
