ZTT-4.00MG

Overview

The ZTT-4.00MG is a ceramic resonator manufactured by ECS Inc., designed for through-hole mounting in SIP-3 packages. It operates at a nominal frequency of 4.0000 MHz with a load capacitance of 30 pF. The component features a frequency tolerance of ±0.5% and an impedance of 30 Ohms. It functions within a temperature range of -20°C to +80°C. This device integrates internal capacitors, simplifying circuit design by eliminating the need for external components typically required with quartz crystals.

Feature Summary

• Integrated capacitor design reduces external component count
• Through-hole mounting for robust mechanical stability
• Wide operating temperature range suitable for general electronics

Applications

• Microcontroller clock circuits
• General-purpose timing applications
• Consumer electronic devices

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required tolerance and package specifications. Confirm RoHS compliance status if environmental regulations apply to the end product. Check availability as some distributors may list lifecycle status changes. Ensure the SIP-3 footprint matches the target PCB layout requirements before procurement.

Selection Notes

Select this component when a cost-effective alternative to quartz crystals is needed for moderate precision timing. The integrated capacitor feature simplifies board space constraints. Consider the ±0.5% tolerance for applications where strict frequency accuracy is not critical. Verify that the 30 pF load capacitance aligns with the microcontroller or oscillator circuit requirements.

Part Context

The ZTT-4.00MG belongs to the ZTT series of ceramic resonators from ECS Inc. This series is characterized by low profile construction and wide frequency ranges. These components are commonly used in timing circuits where size and cost efficiency are prioritized over the high stability offered by crystal oscillators.
