Procurement Notes
Verify current availability status as this component may be subject to end-of-life restrictions or limited distribution channels. Confirm that the specific suffix matches the required package type for your manufacturing process. Ensure compatibility with existing PCB footprints before procurement. Check for updated datasheets to confirm any design-in changes.
Selection Notes
Select this component when a 1500 Ohm impedance match is required at 455 kHz. Consider the surface-mount form factor for space-constrained designs. Evaluate thermal requirements against the standard operating range. Compare insertion loss specifications if detailed performance data is available in the official datasheet.
Part Context
This part belongs to the Murata CERAFIL family of ceramic filters. These components are widely used in consumer electronics and industrial equipment for fixed-frequency filtering. The CFWKA series typically offers robust performance in compact packages suitable for modern surface-mount technology lines.
Replacement Considerations
Consult official Murata documentation for direct cross-reference part numbers. Verify mechanical dimensions and pinout compatibility before substitution. Ensure electrical parameters such as center frequency and impedance remain within acceptable tolerances for the target application.
