SMD Wire Wound Ceramic Chip Inductors - CT Series
CT 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 custom designs are
available.
Features
RoHS compliant.
Ceramic body and wire wound construction provide highest SRFs
Exceptional Q values even at high frequencies
Highest possible SRFs as well as excellent Q values
The non-magnetic coil form assures utmost thermal stability,
predictability and batch consistency
Applications
RF products for cellular phone
GPS receiver
Base Station
Repeater
Wireless LAN/ mouse/ keyboard/ earphone
Remote control
Security system and other RF modules
