The Würth Elektronik 74477120 is a shielded surface-mount power inductor from the WE-PD series. It features a drum core wirewound construction with ferrite core material, providing an inductance of 100 µH at 100 kHz/250 mV test condition. The component is rated for a maximum DC current of 1.6 A (ΔT=40K) and a performance rated current of 2.8 A per IEC 62024-2-2020 Class C. Saturation current is 1.7 A typical at 10% inductance drop and 2.2 A at 30% drop. DC resistance is 135 mΩ typical and 160 mΩ maximum. Self-resonant frequency is 6.6 MHz typical. Operating voltage is 120 V DC maximum.
The inductor is qualified to AEC-Q200 Grade 1, making it suitable for automotive applications. It is RoHS3 compliant, REACH conform, and halogen free. Moisture sensitivity level is MSL 1. Operating temperature range is -40°C to +125°C. Storage conditions require temperature below 40°C and humidity below 75% RH in original packaging.
The component is surface mount in a nonstandard package with dimensions 12.0 mm x 12.0 mm x 6.0 mm max. It is shielded for reduced electromagnetic interference. The recommended land pattern is provided in the datasheet. This inductor is suitable for power supply circuits, DC-DC converters, and EMI filtering in automotive and industrial applications.
