CDBKB455KCAY07-R0

Overview

The CDBKB455KCAY07-R0 is a ceramic signal conditioning filter manufactured by Murata Electronics, belonging to the CERAFIL series. It operates at a center frequency of 455 kHz with a bandwidth of 4 kHz. The component utilizes surface-mount technology (SMD/SMT) for board mounting and functions as a discriminator filter. It supports an operating temperature range from -20°C to +80°C and exhibits moisture sensitivity. The device is packaged in reels, cut tape, or MouseReel formats.

Feature Summary

• Provides precise signal discrimination at 455 kHz using ceramic filter technology
• Designed for surface-mount integration into printed circuit boards
• Operates reliably within standard industrial temperature limits

Applications

• Intermediate frequency stages in AM radio receivers
• Signal processing circuits utilizing Motorola MC3357 demodulators
• Audio signal conditioning in communication equipment

Procurement Notes

Verify current availability status as this component is listed as end-of-life. Confirm specific packaging requirements such as reel or cut tape format during ordering. Check RoHS compliance documentation for regulatory adherence. Ensure storage conditions account for moisture sensitivity classification prior to soldering.

Selection Notes

Select this component when a 455 kHz discriminator response is required for SMT assembly. Compare bandwidth specifications against system requirements to ensure adequate selectivity. Verify footprint compatibility with existing PCB layouts. Consider alternative ceramic filters if lead times for legacy parts are prohibitive.
