WE-TFCH Common Mode Power Line Chokes

WE-TFCH Common Mode Power Line Chokes

Wurth Electronics WE-TFCH series is a low-profile common-mode choke for low-power mains applications.

The maximum height of these common-mode chokes is only 12.3 mm. They are designed for use in LED drivers, metering, and white goods applications. A wide range of impedance values makes it easy to find the part with the best EMI suppression for the power supply. In addition, the WE-TFCH has a 1% stray inductance for symmetrical interference suppression.

Characteristics
  • Approximate 1% stray inductance for symmetrical interference suppression
  • Operating temperature: –40°C to +125°C
Applications
  • Mains filter
  • Suppression of common mode noise
  • Compact switch mode power supplies
  • Electronic ballast applications (LED bulb)
  • Lighting and white goods
