ZTB500E

Overview

The ZTB500E is a ceramic resonator manufactured by ECS Inc., designed for through-hole mounting applications. It operates at a nominal frequency of 500 kHz with a tolerance of ±0.3%. The component utilizes a radial box package with two leads spaced at a 5.00 mm pitch. It functions within an operating temperature range of -20°C to +80°C and complies with RoHS standards. This device serves as a cost-effective timing solution for microcontroller circuits requiring stable clock signals.

Feature Summary

• Provides stable oscillation timing via ceramic resonance technology
• Supports through-hole assembly for robust PCB integration
• Complies with environmental safety standards including RoHS

Applications

• Microcontroller clock generation circuits
• Low-cost timing references in consumer electronics
• Embedded system oscillator modules

Procurement Notes

Verify component availability status carefully, as the ZTB500E is listed as obsolete by major distributors. Confirm lead times and end-of-life management strategies with suppliers before finalizing design implementations. Ensure that any substitute components maintain identical electrical characteristics and mechanical dimensions to guarantee circuit compatibility.

Selection Notes

Select this component when a low-cost, through-hole ceramic resonator is required for 500 kHz applications. Consider the limited operating temperature range of -20°C to +80°C against environmental requirements. Evaluate mechanical fitment based on the 5.00 mm lead pitch and radial box package dimensions during PCB layout planning.

Part Context

The ZTB500E belongs to the family of ceramic resonators produced by ECS Inc. These components bridge the gap between discrete crystal oscillators and less accurate RC timers, offering improved stability at lower costs. They are commonly utilized in simple digital logic circuits where moderate frequency precision suffices.

Replacement Considerations

As the ZTB500E is marked obsolete, identify cross-compatible ceramic resonators from other manufacturers. Verify that substitutes match the 500 kHz frequency, ±0.3% tolerance, and 5.00 mm lead pitch specifications to ensure direct replacement without redesigning the host circuit board.
