74437529203101 is a shielded round-wire SMT high-current inductor from Würth Elektronik's WE-HCF family. It is designed for surface mount assembly in a 2920-style nonstandard package measuring 28.00 mm x 25.00 mm x 20.50 mm. The component uses a manganese-zinc ferrite core and is specified for an operating temperature range of -40°C to +125°C.
The inductor provides a nominal inductance of 100 µH with ±20% tolerance, measured at 100 kHz / 10 mA. Its rated current is 11.2 A maximum at a 50 K temperature rise, with a performance rated current of 10.5 A at 40 K following IEC 62024-2-2020. Typical saturation current is 7 A for a 10% inductance drop and 9.4 A for a 30% drop. DC resistance is 22.9 mΩ typical and 25.19 mΩ maximum at 20°C, and the self-resonant frequency is 4.3 MHz typical.
With a 250 V operating voltage rating, this inductor suits power conversion and filtering applications where high DC bias and stable inductance are required. Its shielded construction helps reduce electromagnetic interference, and the AEC-Q200 rating indicates suitability for automotive electronics.
