CFULB455KC2A-B0

Overview

The CFULB455KC2A-B0 is a ceramic bandpass filter manufactured by Murata Electronics, designed for signal conditioning applications. It operates at a center frequency of 455 kHz with a bandwidth of 12.5 kHz and a nominal impedance of 1.5 kOhms. The component utilizes a cube package with four PC pins for through-hole board mounting. It functions within an operating temperature range of -20°C to +80°C.

Feature Summary

• Provides precise signal filtering at the standard 455 kHz intermediate frequency
• Utilizes robust ceramic construction for stable performance in signal conditioning circuits
• Features a compact cube form factor suitable for space-constrained board layouts

Applications

• Intermediate frequency stages in AM radio receivers
• Signal processing in analog communication equipment
• Audio frequency filtering in legacy broadcast systems

Procurement Notes

This component is officially classified as obsolete and is no longer manufactured by Murata Electronics. Verification of current availability requires checking authorized distributors for remaining stock or identifying approved replacement parts. Ensure any sourced units are genuine and match the original specifications before integration into designs.

Selection Notes

Select this part only if the design specifically requires a 455 kHz center frequency with 12.5 kHz bandwidth and 1.5 kOhm impedance. Due to its obsolete status, engineers should evaluate alternative components that offer equivalent electrical characteristics and compatible pin configurations for new production runs.

Part Context

The CFULB455KC2A-B0 belongs to Murata's CERAFIL series of ceramic filters. These components are engineered for high selectivity and stability in fixed-frequency applications. The specific model represents a legacy solution widely used in traditional analog electronics before the widespread adoption of digital signal processing techniques.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Engineers must consult Murata technical support or authorized distributors to identify valid cross-references or modern equivalents that meet the required 455 kHz specification.
