• Frequency selection in broadcast equipment

Procurement Notes

Verify the exact part number suffix to ensure correct impedance and bandwidth specifications, as variations exist within the CFWLB series. Confirm RoHS compliance status via the official datasheet before integration. Check for End-of-Life notices or product withdrawal announcements from Murata Electronics to assess long-term availability and supply chain stability for production planning.

Selection Notes

Select this component when a 2 kOhm impedance ceramic filter is required at 455 kHz. Ensure the PCB layout accommodates the 5-pin through-hole footprint and the specified dimensional constraints. Compare against other CFWLB variants if different impedance levels or bandwidths are needed for the specific circuit design requirements.

Part Context

This component belongs to the Murata CERAFIL CFWLB series of ceramic filters. These devices are engineered for reliable performance in fixed-frequency applications. The series offers various impedance options and packaging styles to suit different circuit board designs and signal processing needs.

Replacement Considerations

Consult Murata documentation for direct substitutes. Verify that any alternative maintains the 455 kHz center frequency, 2 kOhm impedance, and compatible mechanical footprint.
