SURFACE MOUNT EMI FILTERS

CHIP FERRITE BEADS

BLM

B Series

The BLM

B Series ferrite beads have been developed to

pass signal frequencies from 10MHz to 100MHz while

exhibiting high impedance characteristics to reduce EMI noise

above these specific frequencies.

FEATURES

Designed to reduce noise above operating frequencies

from 10 to 100MHz

High impedance characteristics

Small size

Suitable for flow and reflow soldering

APPLICATIONS

Computers and peripheral equipment

Consumer products

High speed circuits

Suitable for circuits with unstable ground
