Frequently Asked Questions
Q: What is a common mode inductor and what does it do in a circuit?
A: A common mode inductor (also called a common mode choke) is a dual-winding inductor wound on a shared ferrite toroidal core. It presents high impedance to common mode noise — signals that appear simultaneously and in-phase on both lines — while passing differential (normal) signals with minimal loss. This makes it ideal for EMI suppression and power line filtering in switching power supplies, motor controllers, and audio circuits.
Q: What applications are these 2mH 5A ferrite inductors suitable for?
A: These common mode inductors are well-suited for a wide range of applications including switching power supplies (SMPS), LED driver circuits, DC-DC converters, inverters, audio equipment, motor drive boards, and general PCB power filtering. The 5A current rating and compact 14×9×5mm size make them a practical choice for both hobbyist projects and professional electronic designs.
Q: How do I install or solder these inductors onto a PCB?
A: These are through-hole style inductors. Simply insert the leads through the appropriate holes on your PCB, ensure correct orientation per your circuit schematic, and solder the leads on the underside. Trim any excess lead length after soldering. Always refer to your circuit design guidelines for proper placement and spacing.
