EMI-filter inductors simplify EMC compliance and accelerate time to market

Dengrove Electronic Components are solving power supply designers’ EMC-compliance challenges with the latest RLS series of surface-mount line inductors from RECOM.

Intended for use in filters to meet EN 55011 Class A or Class B EMC standards, the inductors are pre-tested and matched with RECOM DC/DC converters to pass not only conducted noise but also radiated interference limits over the full frequency range.

Using a series inductor offers extra confidence that products will pass compliance tests when submitted to an independent laboratory, ultimately securing fast certification for rapid time to market and lower development costs. In contrast, typical inductors for power supply filter applications are often tested for conducted emissions only and can display differing performance at multiple test frequencies, conceivably delaying certification and incurring extra re-engineering and re-testing costs.

The series inductors are RoHS and REACH compliant and offered in inductance values from 3.9µH to 100µH and rated current from 0.63A to 1.89A.
