Tyco Electronics introduces a new line of surface
mountable RFI filters specifically designed to eliminate
noise on the signal line. These board level filters attenuate
noise on the signal line at the frequency range of 10 MHz
to 1000 MHz with maximum attenuation at 40 MHz to 400
MHz.
Ferrites:
Type:
Inductance:
High resistivity, nickel zinc ceramic
2 µH
The U shaped ferrite features a parallel first and second leg
with a center leg surrounded by a grounding/shorting strap
and a capacitor for each line. This unique design
optimizes the filter performance by combining the elements
into one low profile single piece filter. Each filter acts on
two signal lines, but can be stacked as an array to allow
performance over multiple lines.
Housing Material:
Glass-filled polyester (UL94V-0)
Dielectric Withstanding Voltage:
Line-to-line and line-to-ground
1000 VAC for
60 seconds
Ratings:
2.2 Amps max.
56.6 Volts max.
The BLF filter can withstand dielectric voltage of 1000 VAC
for 60 seconds, thereby allowing placement of this filter at
the optimal location, immediately behind the connector.
This placement allows immunity protection from signal line
interference as well as significant reduction of RFI
emissions. The filter can be used in conjunction with
unfiltered RJ jacks, ganged jacks, or with filtered modular
jacks for additional protection.
