744281471 Description

Short technical summary and product information.

The Würth Elektronik 744281471 is a WE-SCC series SMT common mode line filter designed for signal line filtering. This component features a nominal inductance of 470µH measured at 100kHz and 100mV, with a typical impedance of 100kΩ at 3MHz and a maximum impedance of 100kΩ. The filter is rated for a maximum DC current of 150mA (based on 40K temperature rise) and a maximum DC resistance of 4.3Ω. It supports a rated voltage of 80V and an insulation test voltage of 250V AC.

 

The device is housed in a horizontal, 4 PC pad surface mount package measuring 7.30mm x 7.30mm with a maximum height of 4.80mm. It operates over a temperature range of -40°C to +125°C and has an MSL rating of 1 (unlimited floor life). The filter is RoHS3 compliant and REACH unaffected per manufacturer specifications.
