744253101 Description

Short technical summary and product information.

This is a surface mount common mode line filter from Würth Elektronik's WE-SL3 series. It is designed for signal line filtering applications, providing high impedance up to 5000Ω to suppress common mode noise.

 

Electrical specifications include 100µH inductance (tolerance +50%/-30%) at 100kHz, 450mA maximum current rating (ΔT=40K), 80V rated voltage (42VAC), and 0.45Ω maximum DC resistance. Leakage inductance is 94nH typical at 1MHz/1mA. Insulation test voltage is 500VAC.

 

The component is housed in a compact SMD package measuring 9.2mm x 6.6mm x 2.5mm. It operates over -40°C to +125°C temperature range and has MSL 1 moisture sensitivity. The case is WE-SL3 with SMD terminations. Flammability rating is UL 94 V-0.

 

This trifilar (3-winding) choke is suitable for power over Ethernet (PoE), audio frequency noise suppression, and CAN bus lines. It is RoHS, REACH, and halogen-free compliant.
