CFWLA455KG1Y-B0

Overview

The Murata Electronics CFWLA455KG1Y-B0 is a ceramic bandpass filter designed for signal conditioning applications. It operates at a center frequency of 455 kHz with a nominal impedance of 2 kOhms. The component utilizes through-hole mounting technology and belongs to the CFW series under the CERAFIL trademark. It is constructed from ceramic materials and supports board mount installation. The device functions within an operating temperature range of -20°C to +80°C.

Feature Summary

• High selectivity for precise signal filtering
• Excellent group delay time characteristics within the passband
• Available in various bandwidth configurations

Applications

• Intermediate frequency (IF) stages in AM radio receivers
• Signal processing circuits requiring 455 kHz filtering
• Analog communication equipment IF sections

Procurement Notes

This component is officially classified as End-of-Life (EOL) by Murata Electronics. Distributors may list it as obsolete or unavailable. Verify current stock status carefully, as availability is limited. Confirm that the part number matches exactly, including suffixes, before procurement attempts. Alternative sourcing should focus on verified surplus channels or direct manufacturer EOL notices.

Selection Notes

Select this component only if a 2 kOhm impedance interface is required for the circuit design. Ensure the PCB layout accommodates through-hole pins suitable for board mounting. Verify that the -20°C to +80°C operating temperature range meets the environmental requirements of the final assembly. Check mechanical dimensions against the datasheet to ensure fit within the enclosure.

Part Context

The CFWLA455KG1Y-B0 is part of Murata's CERAFIL line of leaded ceramic filters. These components are engineered for high performance in analog signal processing. The CFW series specifically targets intermediate frequency applications. This model represents a specific impedance and bandwidth variant within the broader family of 455 kHz ceramic filters produced by Murata.

Replacement Considerations

CFWLB455KEFA-B0: Similar 455 kHz ceramic filter but with 1.5 kOhm impedance. CFWLA455KF1Y-B0: Alternative variant within the same series. Verify impedance and physical pinout compatibility before substitution.
