CFWLB455KE1Y-B0

Overview

The Murata Electronics CFWLB455KE1Y-B0 is a miniature, high-performance ceramic filter designed for signal conditioning applications. It operates at a center frequency of 455 kHz with an impedance of 1.5 kOhms. The device features a 7.5 kHz bandwidth and utilizes a five-pin cube package for through-hole board mounting. It functions within a temperature range of -20°C to +80°C.

Feature Summary

• Miniature high-performance ceramic construction
• Five-pin cube package design
• Through-hole board mount configuration

Applications

• Signal conditioning circuits
• Intermediate frequency filtering in communication systems

Procurement Notes

Verify component authenticity and datasheet alignment before integration. Confirm that the specific suffix denotes the correct pin configuration and packaging variant. Ensure compatibility with existing PCB footprints and thermal management requirements during final validation.

Selection Notes

Select this component when a 455 kHz center frequency and 1.5 kOhm impedance are required. The 7.5 kHz bandwidth suits narrowband applications. Choose the through-hole cube package for manual assembly or specific mechanical retention needs over surface-mount alternatives.

Part Context

This part belongs to the Murata CERAFIL CFWLB series of ceramic filters. These components are engineered for reliable performance in standard electronic assemblies requiring precise frequency selection. The series offers various impedance and bandwidth options within the same physical form factor.

Replacement Considerations

Direct substitutes include CFWLB455KCFA-B0 and CFWLB455KDFA. Verify that alternative parts match the 1.5 kOhm impedance and 455 kHz frequency specifications exactly.
