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.
