744303012 Description

Short technical summary and product information.

The 744303012 is a WE-HCM series high current flat wire inductor from Würth Elektronik. It features a shielded drum core wirewound construction with a manganese zinc ferrite core. The inductor offers 120 nH nominal inductance (±20%) measured at 100 kHz / 10 mA. Rated current is 31 A maximum based on a 40 K temperature rise, with a performance rated current of 63.9 A per IEC 62024-2-2020 Class D. Saturation current is 51.2 A typical at 10% inductance drop and 59.8 A typical at 30% drop. DC resistance is 0.325 mΩ nominal (±7%) at 20 °C. Self-resonant frequency is 150 MHz typical. The component is housed in a nonstandard surface mount package measuring 10.2 mm x 7.0 mm x 5.0 mm maximum. Operating temperature range is -40 °C to +125 °C. The inductor is RoHS, REACH, and halogen free compliant, with MSL 1 and AEC-Q200 Grade 1 qualification. It is suitable for high current power supply filtering, DC-DC converters, and automotive electronics where low DCR and high saturation current are required.
