CDBLB455KCAX18-B0

Overview

The CDBLB455KCAX18-B0 is a ceramic bandpass filter from the Murata CERAFIL series, designed for signal conditioning applications. It operates at a center frequency of 455 kHz and features a nominal impedance of 2 kOhms. The component utilizes a radial leaded package suitable for board mounting. It functions as an effective radiation discriminator, specifically noted for compatibility with Motorola MC3371 circuits. The device supports a wide operating temperature range from -20°C to +80°C.

Feature Summary

• Small in size and light weight
• Adjustment free at detection circuit
• High sensitivity and stability

Applications

• Motor control systems
• Signal conditioning circuits
• Discriminator applications for Motorola MC3371

Procurement Notes

Verify current availability status as distribution channels may vary. Confirm RoHS compliance details through official manufacturer documentation before integration. Ensure the specific suffix matches design requirements for impedance and frequency characteristics. Check for end-of-life notices or alternative part recommendations directly from Murata Electronics.

Selection Notes

Select this component when a 455 kHz ceramic filter with 2 kOhm impedance is required for AM detection or motor control. The radial package facilitates through-hole assembly. Consider the operating temperature range and physical dimensions against PCB layout constraints. Verify compatibility with existing detector ICs such as the Motorola MC3371.

Part Context

This part belongs to the CERAFIL family of ceramic filters manufactured by Murata Electronics. These components are engineered for reliable performance in intermediate frequency (IF) applications. The series offers standardized products with high stability, reducing the need for manual adjustment in detection circuits during production.

Replacement Considerations

Consult Murata Electronics for direct substitutes if this part is discontinued. Cross-reference specifications such as center frequency, bandwidth, and impedance when evaluating alternatives. Ensure mechanical footprint compatibility for radial leaded packages.
