Filtered Modular
Jack Connectors
Protecting signals from electromagnetic interference
(EMI) is now more important than ever. Spectrum
Control gives you more choices in keeping your signals
clean and free of EMI. Whatever the level of protection
your application requires, we offer signal conditioning
products that meet any level of price and performance.
These compact, low-cost, filtered printed circuit
board RJ45 modular jack connectors from Spectrum
Control offer an inexpensive way to protect equipment
from conducted and radiated electromagnetic interfer-
ence (EMI), while meeting all appropriate performance
requirements. Offering compact size and high reliability,
these new connectors are fully intermateable and
interchangeable with existing standard product. The
low profile and narrow width of the multi-port style
allows more ports to be packed into less space.
Ferrite filtered versions can be supplied in fully
shielded, partially shielded or unshielded versions.
Redundant shielding tabs ensure that a low impedance
ground path is maintained across the interface; tabs are
available in board-ground or panel-ground versions, with
panel-ground jacks also incorporating board-ground legs.
These flame retardant polyester thermoplastic connectors
are compatible with wave solder environments, and
employ duplex plated contacts with solder tails.
Modular jack connectors assist with FCC Part 15
A & B; and CISPR 22 compliance.
Applications for this type of connector are widely
diversified and include: LANs, WANs, network cards,
broadband transmission equipment, workstations,
peripherals, fax/modems, copy machines and
multiplexing.
