BLMP Series
The BLMP Series ferrite beads offer high frequency noise
suppression with the capability of handling large currents for
DC power line applications.
FEATURES
■ Suitable high frequency noise suppression over wide
frequency range
■Current rating up to 6 AMPS
■Small package size–EIA STD 0603/0805/1206 and 1806
■Nickel barrier terminations provide excellent solder
heat resistance
■Low DCR
APPLICATIONS
■ High current DC power lines
■Circuits where a stable ground is unavailable
