ZTB540P

Overview

The ZTB540P is a ceramic resonator manufactured by ECS Inc. designed for through-hole mounting applications. It operates at a fundamental frequency of 540 kHz with a tolerance of ±0.3%. The component functions within an operating temperature range of -20°C to +80°C. It utilizes a radial, box package configuration featuring two leads spaced at a 5.00mm pitch. This device serves as a cost-effective timing solution for electronic circuits requiring stable frequency generation without the complexity of quartz crystals.

Feature Summary

• Provides stable frequency generation using ceramic resonance technology
• Supports through-hole mounting for reliable PCB integration
• Operates effectively across standard industrial temperature ranges

Applications

• Microcontroller clock sources
• Simple oscillator circuits
• Timing references in consumer electronics

Procurement Notes

Verify component authenticity and datasheet revisions upon procurement. Confirm that the specific batch matches the required temperature rating and tolerance specifications. Check for obsolescence status as indicated by distributor listings. Ensure packaging integrity remains intact during storage and handling to prevent lead damage or contamination prior to assembly.

Selection Notes

Select this component when a low-cost alternative to quartz crystals is required for fixed-frequency applications. Consider the ±0.3% tolerance limit for timing accuracy requirements. Evaluate the thermal stability constraints against the operational environment. Ensure the through-hole form factor aligns with the target printed circuit board design and manufacturing capabilities.

Part Context

This part belongs to the family of ceramic resonators produced by ECS Inc. These components are generally utilized in applications where moderate frequency stability suffices. They offer a balance between performance and cost compared to higher-precision oscillators. The specific model designation indicates its unique electrical characteristics and physical dimensions within the manufacturer's catalog.

Replacement Considerations

Distributor data indicates the lifecycle status as obsolete. Verify availability of direct substitutes from ECS or other manufacturers offering equivalent 540 kHz ceramic resonators with matching package dimensions and tolerance ratings before finalizing design changes.
