744042003 Description

Short technical summary and product information.

The 744042003 is a shielded, drum core, wirewound fixed inductor from Würth Elektronik's WE-TPC series. It features an inductance of 3.3µH ±30% measured at 100 kHz and 100 mV, with a rated current of 1.95A maximum at a 30K temperature rise. The DC resistance is 50mOhm typical and 65mOhm maximum at 20°C. The saturation current is typically 1.8A. The self-resonant frequency is typically 80 MHz.

The inductor is housed in a surface mount package 1919 (4848 Metric) measuring 4.80mm x 4.80mm x 2.00mm. The ferrite core is fully shielded for reduced electromagnetic interference. Operating temperature range is -40°C to 125°C, with ambient temperature for rated current limited to -40°C to 95°C. Storage conditions are <40°C and <75% RH.

The component is RoHS compliant, REACH conform or declared, halogen free per JEDEC JS709B and IEC 61249-2-21, and has MSL level 1 (unlimited floor life). Typical applications include power supply filtering and DC-DC converter circuits in general electronic equipment.
