Filtered Modular Jacks – PCRJ Series
This product is not RoHS-compliant. Contact Coilcraft
for current status or possible alternatives.
These filtered jacks virtually eliminate conducted and radiated noise in voice or data lines. And they suppress noise
at the best possible spot for incoming and outgoing signals.
Available in RJ-45, -14 and -11 versions, they use a single
high impedance magnetic structure to filter multiple signal
lines simultaneously, providing common mode noise reduction ­without affecting the desired signal — something
ferrite beads or sleeves can’t achieve.
The -1 series jacks reduce common mode noise by 45 dB at
100 MHz while passing signals up to 48 MHz without attenuation; the -2 versions provide 20 dB attenuation at 100 MHz
and pass differential mode signals up to 140 MHz.
The jacks come standard with a solderable shield and
match standard industry footprints. Custom models are
available to meet specific response characteristics.
