SMD Wire Wound Ceramic Chip Inductors - BWCM Series
BWCM Series
Due to accurate wire winding technology, these chip inductors are
designed for filtering impedance matching, resonance and choke
circuits for RF designer. Both standard series and custom designs
are available.
Features
RoHS Compliant
Ceramic body and wire wound construction provide high SRFs
Exceptional Q value even at high frequencies
Ceramic construction delivers the highest possible SRFs as well
as high Q value
Low DC resistance design supports low loss, high output and
low power consumption
CM series is standard for RF designers
Applications
RF products for cellular phone
GPS receiver
Base Station
Repeater
Wireless LAN/ mouse/ keyboard/ earphone
Remote control
Security system and other RF modules
