CFWLB455KD1Y-B0

Overview

The Murata CFWLB455KD1Y-B0 is a five-element leaded ceramic bandpass filter designed for signal conditioning applications. It operates at a center frequency of 455 kHz with a nominal impedance of 1.5 kOhms. The component utilizes through-hole mounting and features a bulk package configuration. It is engineered to function within an operating temperature range from -20°C to +80°C. This device belongs to the CERAFIL series, providing narrowband filtering capabilities essential for intermediate frequency stages in communication systems.

Feature Summary

• Five-element leaded ceramic construction for stable signal conditioning
• Narrowband filtering capability centered at 455 kHz
• Through-hole board mount design for reliable integration

Applications

• RF and IF signal processing circuits requiring narrowband filtering
• Intermediate frequency stages in communication equipment
• Signal conditioning modules in electronic assemblies

Procurement Notes

Verify current availability status as this component may be subject to end-of-life restrictions. Confirm that the specific leaded package and 1.5 kOhm impedance match the target circuit requirements. Ensure compatibility with existing through-hole assembly processes. Check for any updated environmental compliance documentation prior to final procurement decisions.

Selection Notes

Select this component when a five-element ceramic filter with 1.5 kOhm impedance is required for 455 kHz applications. Consider the through-hole form factor if surface space is limited or mechanical robustness is prioritized. Verify that the operating temperature range meets the environmental conditions of the intended application site.

Part Context

This part belongs to the Murata CERAFIL series of ceramic filters. It shares the 455 kHz center frequency characteristic with other models in the lineup but differs in element count and impedance. The leaded construction distinguishes it from surface-mount alternatives like the CDB or CFU series, offering a traditional mounting solution for specific legacy or high-reliability designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Designers should consult official Murata documentation for potential cross-references or contact the manufacturer directly for approved replacements.
