SwitchMode Transformers

Common Mode Chokes

We provide a number of ranges of Common Mode Chokes.

The Common Mode Chokes are available in sizes ranging from standard to ultra miniature in both DIL and SMD styles and offer compatibility with all common footprints.
  Common Mode Chokes

AS Series - HF 20-200kHz

AS Series Current Sensors are designed as a low cost method of controlling, monitoring or measuring AC currents.

The sensors serve as feedback elements between the output and pulse control circuitry providing accurate regulation of switch mode power supplies.
  AS Series - HF 20-200kHz
