Common mode inductors eliminate noise in power supply lines

Triad Magnetics released its CMT-8100 series common mode inductors, which feature rugged construction and materials to support high-temperature applications in demanding electronics operating environments.

CMT-8100 series inductors are used in various types of power supplies to eliminate noise common to all lines. They offer high EMI suppression over a wide frequency spectrum and a high current capacity.  Meeting VDE, IEC, UL, and CSA requirements, they minimize AC line transmitted interference often created by high frequency switching power supplies. Normally placed close to the input power source, the compact CMT-8100 series inductors are constructed with reliable UL rated materials.

The CMT-8100 series inductors are intended for use in designs for industrial controls, plant instrumentation and heavy duty equipment.  In many plant, factory and commercial business environments, the number of devices operating and the high density of their placement for operational efficiency lead to noise problems.  The highly reliable filtering provided by the CMT-8100 Series ensures equipment operates reliably in these challenging high density environments.
