ECM Axial Molded Choke
MF Series
§ High Temperature Tolerance
§ High Solvent Resistance
§ Low EMI
§ Typical Reel Size 1500pcs
The MF range of encapsulated axial chokes from ECM have been especifically designed to cope with
high current at temperatures up to 125oC, with minimum ppm / oC losses.
Its physical construction, while not offering complete EMI shielding, generates extremely low magnetic
interference and has a typical degree of coupling at 3o max. All the components in this range are
hermetically sealed and solvent resistant, conforming to MIL-STD-202F-213B
