Constructed with a ferrite drum core and wirewound winding, it provides 1.2A RMS current rating and 1A saturation current with 220m\u03a9 maximum DC resistance. The shielded construction minimizes magnetic field radiation for EMI-sensitive applications. AEC-Q200 qualified and rated for -40\u00b0C to +125\u00b0C operation, it is designed for automotive DC-DC converters and power filter applications.","working_principle":"The SRU1048A uses a shielded drum core construction where the wirewound coil is wrapped around a cylindrical ferrite core and enclosed by a ferrite shield. This configuration concentrates the magnetic flux within the shield, reducing external field radiation and preventing coupling with nearby components. The ferrite core material provides high permeability for achieving the specified inductance in a compact form factor. Saturation current is defined at the point where inductance drops by 30% from its nominal value.","pin_description":"
