7440530047 Description

Short technical summary and product information.

The Würth Elektronik 7440530047 is a shielded wirewound power inductor from the WE-TPC series. It offers an inductance of 4.7µH with ±30% tolerance, measured at 100kHz/100mV. The component is rated for a maximum current of 2.4A based on a 30K temperature rise, with a typical saturation current of 1.95A (ΔL/L < 35%). DC resistance is 30mΩ typical and 38mΩ maximum at 20°C. The self-resonant frequency is 40MHz typical.

Designed for surface mount assembly, the inductor comes in a 2323 (5858 Metric) package measuring 5.8mm x 5.8mm x 3.0mm. The ferrite core and shielding help reduce electromagnetic interference. Operating temperature ranges from -40°C to +125°C, with ambient temperature for rated current limited to +95°C. Storage conditions are below 40°C and 75% relative humidity.

This inductor is suitable for general electronic equipment such as power supplies and DC-DC converters. It complies with RoHS, REACH, and halogen-free standards, and has a moisture sensitivity level of 1. The datasheet provides detailed electrical and mechanical specifications.
