CFULB455KD1Y-B0

Overview

The CFULB455KD1Y-B0 is a ceramic bandpass filter from Murata Electronics' CERAFIL series, 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 a through-hole mounting style and features a cube package configuration with four pins. It is engineered to function within an operating temperature range of -20°C to +80°C.

Feature Summary

• Utilizes ceramic construction for stable signal filtering performance
• Designed for board mount installation via through-hole technology
• Optimized for intermediate frequency signal conditioning

Applications

• Intermediate frequency stages in communication receivers
• Signal conditioning circuits requiring 455 kHz selectivity
• Audio processing equipment using standard IF frequencies

Procurement Notes

Verify current availability status as the component may be subject to end-of-life restrictions. Confirm that the 1.5 kOhm impedance and 455 kHz center frequency align with specific circuit requirements before integration. Ensure compatibility with existing through-hole assembly processes and thermal profiles during soldering.

Selection Notes

Select this component when a 455 kHz ceramic filter with 1.5 kOhm impedance is required for through-hole PCB designs. Consider the -20°C to +80°C operating range against environmental conditions. Evaluate mechanical fit within the cube package constraints relative to adjacent board components.

Part Context

This part belongs to the Murata CERAFIL family of ceramic filters, specifically the CFULB series. These components are widely recognized for their reliability in analog signal processing tasks.
