744227 Description

Short technical summary and product information.

The Würth Elektronik 744227 is a WE-SL2 series surface-mount common mode line filter designed for power and signal line applications. It features a 2-winding bifilar or sectional winding construction with an inductance of 51 µH (measured at 1 kHz, 100 mV) and typical impedance of 5.5 kΩ at 10 MHz.

 

The component has a maximum DC resistance of 160 mΩ and a rated current of 1 A (ΔT = 40 K). Rated voltage is 80 V, and insulation test voltage is 500 V AC. Leakage inductance is typically 85 nH at 1 MHz. The filter operates over a temperature range of -40°C to +125°C, with ambient temperature for rated current from -40°C to +85°C.

 

The 744227 is supplied in a horizontal, 4-pin SMD package measuring 9.2 mm × 6.0 mm × 5.3 mm (max). It is qualified to AEC-Q200 Grade 1 and has a moisture sensitivity level of 1 (unlimited). The component is RoHS3 compliant, REACH conform, and halogen-free per JEDEC JS709B and IEC 61249-2-21.
