Surface Mount EMI Filters
our family of surface mount
filters is designed to provide
a range of high performance
EMI filtering options with
a minimal PCB footprint
SA Series Arrays
incorporate four lines
in one compact footprint. These arrays
are nonpolar and designed to minimize
residual inductance, thereby ensuring
large insertion loss in a wide band
and better cross talk control…
SM8-SM9
Three Terminal Chips
offer superior ability
to withstand transient voltages and surges,
and deliver excellent filtering performance
in high current applications while providing
exceptional solderability and resistance to
solder heat…
SM2-SM7
SSM Square Surface Mount
square
mechanical geometry enhances SMT
soldering in applications up to 10 Amps.
These filters come in a Pi circuit configuration
and are designed to address EMI/RFI on
crowded printed circuit boards…
SM12-SM13
MSM Mini-Surface Mount
offers a
multilayer electrode structure, high
temperature construction and 10 Amps
current ratings. The filter chips provide
extreme elimination of residual inductance
and the self-resonant frequency extends
the microwave band…
SM11
PSM Power Surface Mount
are the first
high temperature surface mount filter designed
to effectively filter EMI/RFI at currents up to
20 Amps. These filters come in either a
Feed-through or Pi circuit configuration
and offer superior high frequency
noise suppression…
SM14-SM15
MSP Mini Surface Mount Power Filters
offers a multilayer electrode structure,
high temperature construction and 10 Amps
current ratings. The filter chips provide
extreme elimination of residual inductance
and the self-resonant frequency extends
to the microwave band…

Advantages of a
Surface Mount Filter
With many years of experience in the design
and manufacture of filters, API Technologies
has a unique perspective on EMI and how to
control it. We provide an integrated approach
to EMC problems with services such as
customer consulting, diagnostic testing,
design and manufacturing. By offering a
variety of custom assemblies, we are able
to unite your specific requirements with our
high performance filters.
API’s Spectrum Control line of 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.
MPC Series Miniature PCB Power Filters
are designed to fit a wide range of environments.
These filters are ideal for personal computers
and peripherals, home appliances, measuring
instruments and medical equipment, and are
all available lead free…
SM17-SM20
High Frequency PCB Filters
provide EMI
filtering to protect low power digital circuits.
With mounting directly on the printed circuit
board, filtering begins at the source of the
problem…
