Filtered Modular
Jack Connectors
Protecting signals from electromagnetic interference
(EMI) is now more important than ever. Spectrum 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
varied levels of price and performance.
These compact, low-cost, filtered printed circuit
board RJ45 modular jack connectors from Spectrum
offer an inexpensive way to protect equipment from
conducted and radiated electromagnetic interference
(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.
Filtered versions can be supplied in shielded or
unshielded versions. Redundant shielding tabs ensure
that a low impedance ground path is maintained
across the interface. These flame retardant polyester
thermoplastic connectors are compatible with wave
solder environments, and utilize 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.
