744043003

The Würth Elektronik 744043003 is a shielded wirewound inductor from the WE-TPC series. It features a ferrite drum core construction with a nominal inductance of 3.3 µH (±30% tolerance) measured at 100 kHz/100 mV. The inductor is rated for a maximum continuous current of 2.15 A at a 30 K temperature rise, with a typical saturation current of 1.8 A. DC resistance is 30 mΩ typical and 35 mΩ maximum at 20°C. The self-resonant frequency is 80 MHz typical, making it suitable for high-frequency applications.

The component is housed in a 1919 (4848 Metric) surface mount package with dimensions 4.80 mm x 4.80 mm x 2.8 mm. It operates over an ambient temperature range of -40°C to +125°C, with the rated current derated for temperatures above 95°C. The inductor is fully shielded to minimize EMI and is compliant with RoHS, REACH, and halogen-free requirements. MSL (Moisture Sensitivity Level) is 1 (unlimited).

Typical applications include DC-DC converters, power supply filtering, and EMI suppression in compact electronic devices. The low profile and high current handling make it suitable for portable and automotive electronics where space is limited.
