Product Description
LEF20 Series Common Mode Power Line Choke
Product Overview

The LEF20 series common mode power line choke is engineered for effective suppression of common-mode interference. Featuring a 2-section winding structure, it delivers high resonance frequency, high pulse strength, and low audible noise. With approximately 2% leakage inductance, it provides symmetric interference suppression. The series complies with EN 60938-2 (VDE 0565-2) and UL 1283 standards, is RoHS-compliant, and suitable for wave soldering processes.

Key Features
  • High resonance frequency thanks to 2-section winding
  • High pulse strength
  • Low whirring noise
  • Approximately 2% leakage inductance for symmetric interference suppression
  • Suitable for wave soldering
  • Compliant with EN 60938-2 (VDE 0565-2) and UL 1283
  • RoHS-compliant
Applications
  • Suppression of common-mode interference
  • Electronic ballasts for lamps
  • Switch-mode power supplies for consumer electronics
