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.
