CFULA455KD4A-B0

Overview

The CFULA455KD4A-B0 is a ceramic filter from the Murata CFW series, designed for signal conditioning applications. It operates at a center frequency of 455 kHz with a bandwidth of 10 kHz. The component features a nominal impedance of 1.5 kOhms and utilizes a cube package with three pins for through-hole mounting. It is classified under the CERAFIL product line.

Feature Summary

• High selectivity for precise signal filtering
• Excellent group delay characteristics within the passband
• Ceramic construction for stable performance

Applications

• Intermediate frequency (IF) stages in AM radio receivers
• Signal processing circuits requiring 455 kHz filtering
• Communication equipment utilizing ceramic filter technology

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 pin configuration and impedance match the target circuit design requirements before integration into production systems.

Selection Notes

Select this component when a 455 kHz center frequency with a 10 kHz bandwidth is required. Ensure the system accommodates a 1.5 kOhm impedance level. The through-hole cube package dictates specific PCB footprint constraints compared to surface-mount alternatives.

Part Context

This part belongs to the Murata CERAFIL family of ceramic filters. These components are widely used in consumer electronics and industrial communication devices where reliable frequency selection is critical. The CFW series designation indicates a standard ceramic filter form factor.

Replacement Considerations

Direct substitutes include other Murata ceramic filters with identical 455 kHz center frequency, 10 kHz bandwidth, and 1.5 kOhm impedance. Verify mechanical dimensions and pinout compatibility for any cross-referenced parts.
