74439370082 Description

Short technical summary and product information.

The Würth Elektronik 74439370082 is a surface mount shielded power inductor from the WE-XHMI series. It offers a nominal inductance of 8.2 µH with ±20% tolerance, measured at 100 kHz and 10 mA. The component is rated for a continuous current of 13 A (ΔT = 40 K) and can handle peak currents up to 15 A at 10% inductance drop and 36.4 A at 30% drop.

 

Its DC resistance is typically 5.5 mΩ with a maximum of 6.05 mΩ at 20°C, and the self-resonant frequency is 11 MHz typical. The inductor is shielded with a metal composite core, minimizing electromagnetic interference. It is qualified to AEC-Q200 Grade 1, making it suitable for automotive applications.

 

Packaged in a nonstandard SMD case measuring 16.4 mm x 15.4 mm x 10 mm, it is designed for high-current power conversion circuits such as DC-DC converters, voltage regulator modules, and filtering applications. The operating temperature range is -40°C to +125°C, and it is RoHS, REACH, and halogen-free compliant.
