Thru-hole Filters
High Frequency PCB Filters
The economical High Frequency PCB Filter offers
electrical characteristics which allow many devices
to meet most government and industry specifications
for EMI control, while providing good electrostatic
discharge protection.
A lossy ferrite filter with a center ground lead is
terminated within the filter’s thermoset epoxy body.

Surface Mount Filters & Inductors
The High Frequency PCB Filter offers savings
three ways. First is the low cost of the filter assembly.
Second is the economy of installation. Three silver
plated leads are inserted into holes in a printed circuit
board which has a ground path circuit, for conventional
flows-soldering with other components. No special
mounting plate or brackets are needed and when the
holes are placed as recommended in a .062 (1.57mm)
thick board, no lead trimming is required. Elimination
of hand soldering provides opportunities for improved
quality in addition to applied-cost benefits.
A third savings results from placing a filter at the
source of an EMI problem, potentially eliminating the
need for additional filtering at other points in the circuit.
