In 1968, Spectrum Control was founded as a
solutions-oriented company designing and
manufacturing products to suppress or
eliminate electromagnetic interference (EMI).
In the years that followed we adapted our
core EMI filter technology into a complete
line of capacitors, discrete filters, filtered
arrays, filtered connectors, power filters,
gaskets and shielding, microwave filters
and power management products. Today,
Spectrum Control offers the most
experienced team of EMI engineering
specialists and most extensive line of EMI
filter products and packaged filter solutions.
Spectrum products are used in virtually
all industries worldwide, including
telecommunications, medical, government,
military, aerospace, computer and industrial
controls. In addition, we’ve secured preferred
supplier status with many of the leading
electronics OEMs around the world.

With many years of experience in the design and manufacture of
filters, Spectrum Control has a unique perspective on EMI and its control.
We are now extending our filter expertise to the board level with our
introduction of a complete line of surface mount EMI filters. Our family of
surface mount inductors, low pass filters, high frequency filters and power
filters is designed to offer high performance EMI filtering with a minimal
PCB footprint.
Spectrum Control surface mount EMI filters are ideal for a wide range of
PCB applications, including automotive electronics, digital A/V equipment,
computers, peripherals, telecommunications, switching power supplies
and high current buss lines.
