ATS-49-R 3.686400

Overview

The ATS-49-R 3.686400 is a fundamental quartz crystal oscillator manufactured by MtronPTI, designed for surface mount applications within the HC-49/US package format. It operates at a nominal frequency of 3.6864 MHz with a load capacitance of 18 pF and a series resistance of 200 Ohms. The component provides a frequency stability of ±50 ppm and supports a drive level of 100 µW. It functions reliably across an operating temperature range from -10°C to +70°C.

Feature Summary

• Fundamental mode quartz crystal construction
• Surface mount HC-49/US compatible packaging
• Standard 18 pF load capacitance specification

Applications

• General purpose clock signal generation
• Microcontroller timing circuits
• Communication interface synchronization

Procurement Notes

Verify the specific suffix requirements against the official MtronPTI datasheet to ensure compatibility with target PCB footprints and thermal profiles. Confirm that the 18 pF load capacitance aligns with the host circuit design. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the operating temperature range meets the system's environmental constraints.

Selection Notes

Select this component when a standard 3.6864 MHz reference is required in a compact surface mount form factor. The 200 Ohm series resistance indicates suitability for moderate drive levels. Consider the ±50 ppm stability for non-critical timing applications where higher precision is not mandatory. Verify the physical dimensions match the available board space.

Part Context

This part belongs to the ATS-49-R series of surface mount crystals from MtronPTI. It utilizes the widely adopted HC-49/US mechanical outline adapted for surface mounting. The series offers various frequency options while maintaining consistent electrical characteristics such as load capacitance and drive level specifications across the product line.

Replacement Considerations

Direct substitutes must match the 3.6864 MHz frequency, 18 pF load capacitance, and HC-49/US SMD footprint. Verify equivalent series resistance and stability ratings. Cross-reference with other manufacturers offering HC-49S or similar surface mount packages.
