Part Number: 9379055002

79 Plate- I25/2.3/18

Planar EQ and EQI 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 EQ cores with their low mass and low profile are suitable for Surface Mount installations in low power filter and transformer applications.

– Planar EQ and EQI cores can be supplied with the center post gapped to a mechanical dimension, or an AL value.
