• Designed for specific signal conditioning requirements

Applications

• Intermediate frequency (IF) filtering in communication systems
• Signal conditioning circuits requiring 455 kHz selectivity
• Electronic equipment utilizing ceramic bandpass filters

Procurement Notes

Verify current availability status as this component may be subject to end-of-life restrictions or discontinuation notices. Confirm that the specific suffix denotes the correct impedance and tolerance variant required for your design. Ensure compliance with RoHS directives if applicable to your manufacturing standards. Cross-reference official datasheets for any recent product change notifications affecting specifications.

Selection Notes

Select this component when a 2 kOhm impedance ceramic filter is required for 455 kHz applications. Compare against similar CFW series parts like CFWLB455KEFA-B0 for impedance differences. Ensure the through-hole package fits the PCB layout constraints. Verify thermal ratings match the operational environment limits of the target device.

Part Context

This part belongs to the Murata CERAFIL CFW series of ceramic filters. These components are widely used in radio frequency and intermediate frequency stages. The series offers various impedance and frequency options. The CFWLA455KF1Y-B0 specifically targets the 455 kHz standard with a 2 kOhm load impedance.

Replacement Considerations

CFWLA455KG1Y-B0 shares the same series and frequency but differs in impedance specifications. CFWLB455KEFA-B0 is another alternative within the same family but features a different impedance value. Verify electrical compatibility before substitution.
