MEDICAL APPLICATIONS
LM SERIES

For Medical and Dental Equipment

The LM Series of EMI filters provides high insertion loss at low frequencies for medical applications subject to stringent conducted emissions standards. The high performance is offered in an extremely low leakage filter design facilitating the development of equipment subject to stringent EMC specifications related to leakage current that are imposed upon electronic equipment used in the medical industry, specifically equipment classified in the "patient contact" category.

The LM Series can augment existing EMI filters in switch mode power conversion/regulation equipment or function as the equipment's stand alone filter.

The LM Series is offered in current ratings from 1.5 to 20 Amps and in a variety of mechanical packages.
