ZTB455E

Overview

The ZTB455E is a ceramic resonator manufactured by ECS Inc., designed for applications requiring stable frequency generation at 455 kHz. This component belongs to the ZTB series and features a radial package with through-hole mounting capabilities, utilizing a pin spacing of 5 mm. It operates within an extended temperature range from -20°C to +80°C and maintains a frequency tolerance of ±0.3%. The device incorporates a built-in load capacitance of 100 pF, simplifying circuit design by eliminating the need for external capacitors in many configurations. Constructed as a high-performance resonator, it supports RoHS compliance standards.

Feature Summary

• Offers low-frequency operation at 455 kHz with extended temperature range capability
• Features integrated 100 pF load capacitance for simplified circuit integration
• Utilizes radial through-hole mounting with 5 mm pin spacing

Applications

• Frequency reference circuits in consumer electronics
• Oscillator stages in communication equipment
• Timing control in industrial instrumentation

Procurement Notes

Verify that the specific order matches the ZTB455E part number to ensure correct 455 kHz frequency and 100 pF internal capacitance. Confirm the requirement for through-hole radial packaging rather than surface mount alternatives. Check datasheet specifications for operating temperature limits between -20°C and +80°C to ensure suitability for the intended environmental conditions. Ensure compliance with RoHS directives if required by the manufacturing process.

Selection Notes

Select this component when a stable 455 kHz reference is needed without external tuning components. The integrated 100 pF capacitance reduces board space and assembly steps compared to discrete crystal solutions. Consider the through-hole form factor for robust mechanical connections in environments subject to vibration. Evaluate the ±0.3% tolerance against system requirements for frequency accuracy. The extended temperature range makes it suitable for applications exposed to moderate thermal variations.

Part Context

The ZTB455E is part of the ZTB series of ceramic resonators produced by ECS Inc. This series focuses on providing cost-effective frequency control solutions for mass-produced electronics. Ceramic resonators like the ZTB455E offer a balance between performance and price, serving as alternatives to quartz crystals where extreme stability is not critical. The 455 kHz frequency is historically significant in intermediate frequency (IF) amplifier stages for radio receivers.

Replacement Considerations

Direct substitutes must match the 455 kHz frequency, 100 pF load capacitance, and through-hole radial package. Verify that alternative components support the same -20°C to +80°C operating range and ±0.3% tolerance. Ensure pin compatibility and footprint alignment for seamless replacement in existing PCB layouts.
