ZTBF500E

Overview

The ZTBF500E is a surface-mount ceramic resonator manufactured by ECS Inc. It operates at a nominal frequency of 500 kHz with a tolerance of ±0.3% and an equivalent series resistance (ESR) of 2 kHz. The component features a two-terminal non-standard SMD package measuring 7.00 mm in length and 3.50 mm in width. It is designed for operation within a temperature range of -20°C to +80°C.

Feature Summary

• Surface mount construction for automated assembly
• High frequency stability with ±0.3% tolerance
• Compact non-standard SMD footprint

Applications

• Microcontroller clock generation
• Low-frequency timing circuits
• Consumer electronics oscillators

Procurement Notes

Verify the specific package dimensions against the official datasheet before PCB layout finalization, as the ZTBF500E utilizes a non-standard SMD form factor. Confirm that the operating temperature range of -20°C to +80°C aligns with the environmental requirements of the target application to ensure long-term reliability.

Selection Notes

Select this component when a precise 500 kHz reference is required in space-constrained designs. The ceramic technology offers a cost-effective alternative to quartz crystals for applications where moderate stability suffices. Ensure the circuit design accommodates the specified ESR value to guarantee reliable oscillation startup.

Part Context

This part belongs to the ZTBF series of ceramic resonators from ECS Inc., which are engineered for general-purpose timing applications. The series provides a balance between performance and size, utilizing surface-mount technology to facilitate efficient manufacturing processes in modern electronic assemblies.

Replacement Considerations

Consult the official manufacturer cross-reference list for verified substitutes. Generic replacements may differ in ESR or tolerance specifications.
