470 nH, 4.5 A — AEC-Q200 shielded power inductor
The Murata DFE2HCAHR47MJ0L is a 470 nH shielded wirewound inductor from the DFE2H series, rated for 4.5 A continuous current with a saturation current of 5.1 A. The 25 mOhm max DCR keeps conduction losses low in power supply filtering and DC-DC converter output stages. AEC-Q200 qualification and a -40°C to +150°C operating range make it suitable for under-hood automotive modules, engine control units, and transmission controllers where ambient temperatures exceed 125°C.
Metal core, shielded construction
The metal composite core provides stable inductance over temperature and DC bias, unlike ferrite cores that saturate more abruptly. The shielded design contains the magnetic flux, reducing EMI coupling to nearby traces and components on a dense PCB.
