744306020 Description

Short technical summary and product information.

The Würth Elektronik 744306020 is a high-current, surface mount fixed inductor, part of the WE-HCM series. It offers a nominal inductance of 200 nH with a ±20% tolerance, measured at 100 kHz/10 mA. The inductor is rated for a maximum current of 25 A at a 40 K temperature rise and has a typical DC resistance of 0.26 mΩ at 20°C. Its self-resonant frequency is typically 51 MHz.

 

This component is designed for robust performance, featuring a shielded drum core with wirewound construction and a Manganese Zinc Ferrite (MnZn) core material. It operates reliably across a wide temperature range from -40°C to 125°C. The nonstandard package measures 10.50 mm in length, 10.30 mm in width, and 5.50 mm in height, making it suitable for various compact electronic designs. It is compliant with RoHS, REACH, and Halogen Free standards, and has a Moisture Sensitivity Level (MSL) of 1.

 

Key electrical characteristics include a performance rated current of 71.2 A max. and saturation currents of 34 A typ. (at 10% inductance drop) and 36.1 A typ. (at 30% inductance drop). These specifications highlight its suitability for applications requiring stable inductance under high current conditions.
