Common Mode Chokes for AC and DC Power Lines
- Technology
- Common mode chokes
- Partner
- Laird
Used in moderate to severe conditions like telecommunications systems, industrial equipment, and automotive power supply, Laird’s extensive portfolio of common mode chokes (CMC) are designed to filter noise and optimise application performance and power supply.
The unique materials withstand high temperature and power situations and will keep your systems running consistently and at top speed.
Constructed from ultra-thin mixtures of iron, nickel, and zinc oxides, Laird Steward ferrite CMC’s are characterised by their size, light weight, low cost, and high reliability. They provide superb electromagnetic interference (EMI) reduction while remaining open to normal circuit operation.
