61 PLANAR E CORE 18/4/10-61
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.
9461222002 is matted with 9361060002.
A high frequency NiZn ferrite developed for a range of inductive applications up to 25 MHz. This material is also used in EMI applications for suppression of noise frequencies above 200 MHz. Excellent stability characteristics.
Strong magnetic fields or excessive mechanical stresses may result in irreversible changes in permeability and losses.
