744231371 Description

Short technical summary and product information.

The Würth Elektronik 744231371 is a surface-mount common mode choke from the WE-CNSW series, designed for signal line filtering applications. It features a typical inductance of 0.478 µH and a nominal impedance of 370 Ω at 100 MHz, with a maximum DC resistance of 450 mΩ and a rated current of 280 mA (ΔT = 40 K).

 

The component is qualified to AEC-Q200 Grade 1, making it suitable for automotive and other high-reliability environments. It operates over a temperature range of -40°C to +125°C and is rated for a maximum voltage of 50 V. The package is a horizontal 4 PC pad configuration measuring 2.00 mm x 1.20 mm with a maximum height of 1.40 mm.

 

The choke is RoHS3 compliant, REACH conform, halogen-free, and has an MSL of 1 (unlimited). It is designed for use in DC/DC converters, CAN bus, and other signal line filtering applications where common mode noise suppression is required.
