CFULA455KG1Y-B0

Overview

The CFULA455KG1Y-B0 is a ceramic filter from the Murata CERAFIL series, designed for signal conditioning applications. It operates at a center frequency of 455 kHz with a nominal impedance of 2 kOhms. The component features a four-element leaded construction housed in a cube package with three pins. It supports through-hole board mounting and functions within an operating temperature range of -20°C to +80°C.

Feature Summary

• Four-element leaded ceramic construction for stable filtering performance
• Designed for narrowband intermediate frequency signal processing
• Through-hole mounting configuration for reliable board integration

Applications

• RF and IF signal processing circuits requiring narrowband filtering
• Intermediate frequency stages in communication equipment
• Signal conditioning in analog receiver architectures

Procurement Notes

This component is officially designated as End-of-Life (EOL) by Murata Electronics. Verification of current availability should be conducted directly with authorized distributors or the manufacturer, as standard supply channels may no longer support new orders. Designers must confirm lifecycle status before finalizing procurement plans.

Selection Notes

Select this part when a 455 kHz center frequency and 2 kOhm impedance are required for through-hole assembly. Ensure the design accommodates the specific pinout and physical dimensions of the four-element leaded cube package. Verify thermal requirements against the specified -20°C to +80°C operating range.

Part Context

The CFULA455KG1Y-B0 belongs to the CFWLA/CFULA family of ceramic filters manufactured by Murata Electronics under the CERAFIL brand. These components are specialized passive devices used primarily in radio frequency and intermediate frequency applications where precise frequency selection is critical for signal integrity.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, designers should consult official Murata replacement guides or engineering support for qualified alternatives.
