LM series cores
LM series cores (μ=8 000) on the base of nanocrystalline material NANOPERM are applied in EMC filters with a large amount of asymmetrical interference currents (as an example, in inverter drives).
Among main advantages of LC series in comparance with ferrites one can note:
- Bsat is 3 times higher at the same permeability values
- small size and low weight
- wideband, particularly, they provide better attenuation at high frequencies
- high maximum operating temperature (>120 °C).
The outer coating - a plastic protective case (the material QMFZ2 E41871, corresponding OBJS2 E209169 и QMFZ2 E41938).
