EMI RFI Filters Selection Guide

FILTERED TERMINAL BLOCKS
Eliminate Electromagnetic Interference (EMI)
UL Standard 1059 Compliant
Te rminal Blo c k s
CTS UL-recognized filtered terminal blocks are specifically designed
to save time and money for EMI filtering applications. By combining
a filtering component with an industry standard terminal block, CTS
has created an effective barrier to EMI noise.
CTS filtered terminal blocks allow the engineer to eliminate EMI
using an existing mechanical design element combined with the
excellent performance of a Pi filter.

Ceramic Trimmer Capacitors
CTS 4700 series Pi and C filters are used where cost and space savings are
a priority and improved insertion loss is required.
CTS leads the way in the miniaturization of ceramic trimmers. The 513
SMT, all-ceramic trimmer capacitor offers outstanding features such as
exceptionally smooth tuning, extra miniaturized - 0.196 diameter x
0.100in height max. (4.98 x 2.54mm) ceramic base & dielectric - very
stable, high Q factor for ultra high frequency applications, wide
temperature range - functional under extreme conditions, SMD on tape
and reel - suitable for automatic pick and place, and rugged construction.
The filter's unique design makes it suitable for common production soldering
processes.
The state-of-the-art manufacturing process results in excellent electrical and
mechanical performance. The square or round body allows easy handling,
positioning and soldering onto the PCB. The 4700 series is another cost
effective, quality product from CTS.

Ceramic Coaxial Resonators
Pi Filter
CTS ceramic coaxial resonators are offered in four sizes and
four dielectric constants with a frequency range from 800MHz
to 5.9GHz. To ensure superior performance and adequate
miniaturization, these parts are made of quality metalized
ceramics. CTS offers the best ceramic composition in order to
meet all necessary temperature performance, shielding and
miniaturization requirements for an endless number of applications.
C Filter
CTS quick-connect and bolt-in filter plate assemblies provide ease of
installation and line customization of standard size plates. Filter plates are
the most efficient and cost effective solution for filtering multiple lines into or
between different system compartments.
For higher frequency applications (above 50MHz), filter plates can be more
effective than typical surface mount solutions. The natural shielding quality of
the plates creates an effective RF barrier that provides excellent insertion loss
and isolation for frequencies above 5MHz. The pre-assembled plates greatly
reduce the time and resources required to individually install solder or
bushing mount filters.
CTS quick connect series of filter plates features a base plate with built-in
installation clips. These clips allow for cost effective mounting into the
system’s bulkhead without the cost associated with traditional hardware.

DISC Ceramic WEECO N ®
Capacitors
Known throughout the industry for quality and reliability,
CTS prides itself on maintaining an excellent track
record in producing high reliability products.
Our DISC ceramic capacitors have three classifications:
Temperature Compensating - highest Q, minute
capacitiance change with temperature, more stable than
glass or mica.
Extended Temperature Compensating - finite and
repeatable capacitance change with temperature, also
high Q and stability.
High Dielectric Constant - high capacitance, low dissipation factor replaces paper, film, glass, mica in general
purpose applications.
CTS WEECONS® have long been the industry standard
and offer the broadest selection of available ceramic
formulations and package sizes. With a capacitance
range of 1 pF to 0.082 mF, WEECON® capacitors offer
a variety of TC materials and tolerances. The range of
temperature characteristics available make the
WEECON® suitable from the ultra stable requirements of
tuned circuits to the general purpose needs for coupling
and bypassing.
Encapsulated with a
hard, bright polymeric
coating, these capacitors are formulated to
provide mechanical
protection under normal environmental
conditions.
Available in 25, 50, 100 and 500 volts
Thickness from 0.1 to 0.175in (depends on voltage)
Square sizes from 0.1 x 0.1 in to 0.6 x 0.6in
Operates efficiently at -55°C to 125°C
