Features
1.
2.
Standard chip size bobbin with wire wound coil provides high reliability, productivity and performance.
WLCW2520HQ Series offers higher Q factors. In addition, current handling has been improved with
significantly lower DCR values. Like all wire wound ceramic chip inductors, the WLCW2520HQ Series
provides exceptional SRFs, tight inductance tolerance and batch consistency.
3.
4.
Wide range inductance and various tolerance options.
RoHS compliant.
Applications
