Surface Mount EMI Filters
PSM & SSM Series
PSM Series filters are the first surface mount
components to effectively filter EMI/RFI on printed
circuit boards operating at currents up to 20 Amps.
SSM Series filters lend themselves for mounting on
densely populated circuit boards where currents of
10 Amps or less are desired. By eliminating the need
to use conventional thru-hole filters at these higher
currents, it will be possible to create an “RF fence”
without expensive RFI bulkheads. SSM & PSM filters
can be installed with pick and place equipment,
providing time and cost savings compared to
installing thru-hole filters.
