ZTBF455E

Overview

The ZTBF455E is a surface-mount ceramic resonator manufactured by ECS Inc. It operates at a nominal frequency of 455 kHz with a tolerance of ±0.3%. The component is designed for extended temperature applications, functioning reliably within an operating range of -20°C to +80°C. As a surface-mount device (SMD), it facilitates automated assembly processes and compact circuit board layouts. This resonator serves as a stable frequency reference for electronic circuits requiring precise timing signals in the intermediate frequency range.

Feature Summary

• Surface mount package design for automated PCB assembly
• Extended temperature operation capability from -20°C to +80°C
• High frequency stability with ±0.3% tolerance

Applications

• Intermediate frequency filtering in communication receivers
• Timing references for microcontroller systems
• Signal processing circuits requiring 455 kHz stability

Procurement Notes

Verify the specific suffix 'E' against official ECS documentation to confirm surface-mount configuration and temperature rating. Ensure compatibility with reflow soldering profiles specified in the datasheet. Confirm that the ±0.3% tolerance meets system requirements. Cross-reference part numbers carefully as similar variants may exist with different mounting styles or tolerances.

Selection Notes

Select this component when a surface-mount solution is required for 455 kHz applications. Consider the extended temperature range if the environment exceeds standard commercial limits. Evaluate the tight ±0.3% tolerance against cost-sensitive alternatives offering wider tolerances. Ensure footprint dimensions match the PCB layout constraints for SMD packages.

Part Context

This part belongs to the ZTB series of ceramic resonators from ECS Inc., which are designed for low-frequency applications. The series typically includes both through-hole and surface-mount options. The ZTBF455E specifically addresses the need for compact, reliable frequency control in modern electronics where space and thermal performance are critical factors.

Replacement Considerations

Consult official ECS substitution guides for equivalent parts. Verify that any alternative maintains the 455 kHz frequency, ±0.3% tolerance, and surface-mount form factor. Check temperature ratings and electrical characteristics for compatibility.
