Inductors offer 1.7-20A current rating

Triad Magnetics Inc. has released a common mode inductor that the company said eliminates common noise to all lines in power supply designs. The CMT-8100 series features rugged construction and materials for high-temperature applications in demanding electronics operating environments such as industrial controls, plant instrumentation and heavy duty equipment, added the company.

The CMT-8100 series inductors are used in various types of power supplies to offer excellent EMI suppression in a wide frequency spectrum and a high current capacity, stated Triad. 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 UL rated materials.

The inductors feature high dielectric strength of 1500VRMS between windings. They operate from -55°C to 105°C, with the rated current yielding a temperature rise of about 35°C. Inductors in the series offer a minimum inductance per winding ranging from 1-50mH, current rating ranging from 1.7-20A and DCR range from 0.006-0.45?.

The devices feature a toroidal construction with through-hole mounting. They come in rectangular packages ranging from 0.76 x 0.425in to 1.7 x 0.9in max with height ranging from 0.90-1.65in depending on the specific model.

The CMT series transformers are priced starting at $2.25 each in quantities of 1000 units with delivery from stock to 8 weeks lead time.
