SMD Wire Wound Ceramic Chip Inductors - BWHQ Series
BWHQ 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
The highest Q factors and low RDC to fulfill the needs of
mobile applications
Applications
RF products for cellular phone
GPS receiver
Base Station
Repeater
Wireless LAN/ mouse/ keyboard/ earphone
Remote control
Security system and other RF modules
