RL-1329 Through Hole Common Mode Choke
The RL-1329 Through Hole Common Mode Choke series is designed to minimize EMI noise in line filtering applications while meeting both U.S. and international safety standards. Featuring a U-core construction and varnish-impregnated windings, these components offer durable performance in high-frequency environments. All units are pre-tinned for straightforward PCB soldering, and a wide variety of standard inductance values and current ratings are available. This series is particularly well-suited for designs requiring compact footprint and balanced performance across dual windings.

The RL-1329 choke series is optimized for filtering EMI noise caused by switching transients in relays, triacs, SCRs, and similar components. Its balanced winding design effectively cancels out noise pulses induced on the power line, maintaining clean signal transmission across the circuit. This makes it ideal for use in SCR/TRIAC controls, power supplies, RFI suppression, and filtering networks.
