744314101

The Würth Elektronik 744314101 is a shielded wirewound surface-mount inductor from the WE-HCI series, designed for high-current power applications. It offers a nominal inductance of 10 µH (±20%) measured at 100 kHz/100 mV, with a rated inductance of 7.5 µH at 3.5 A. The component handles a rated current of 3.5 A (ΔT=50K) and a performance rated current of 5.3 A (ΔT=40K, per IEC 62024-2-2020).

Electrical characteristics include a typical DC resistance of 33 mΩ at 20°C and a self-resonant frequency of 40 MHz. Saturation current is rated at 1.8 A typical for a 10% inductance drop and 4 A typical for a 30% drop. The inductor operates over a temperature range of -40°C to +150°C and is AEC-Q200 qualified, making it suitable for automotive and other demanding environments.

The component comes in a 7050 package (7.00 mm × 6.90 mm × 5.00 mm) with surface-mount termination. It is RoHS3 compliant and has a moisture sensitivity level of 1 (unlimited). The shielded construction helps minimize electromagnetic interference in dense PCB layouts.

This inductor is well-suited for DC-DC converters, power supplies, and filtering circuits where high current handling and stable inductance are required. Its compact footprint and high-temperature rating support reliable operation in space-constrained designs.
