ATS200CSM-1E

Crystals Overview

The ATS200CSM-1E is a surface-mount MHz crystal manufactured by CTS-Frequency Controls. It operates at a nominal frequency of 20 MHz with a frequency tolerance of ±30ppm and stability of ±50ppm. The component features an 18pF load capacitance and 30 Ohms equivalent series resistance (ESR). Designed for fundamental mode operation, it utilizes the HC-49/US-SM package, measuring 11.10mm x 4.83mm x 4.30mm. It supports a commercial operating temperature range of -20°C to +70°C and complies with RoHS3 standards.

Crystals Feature Summary

• Surface mount design in HC-49/US-SM package
• Fundamental mode operation at 20 MHz
• RoHS3 compliant construction

Crystals Applications

• General purpose clock generation circuits
• Microcontroller system timing references
• Digital logic interface synchronization

Crystals Procurement Notes

Verify the specific suffix 'E' against the manufacturer's current datasheet to confirm if it denotes lead-free compliance or a minor mechanical variation compared to the base model ATS200CSM-1. Ensure the ordering documentation explicitly matches the full part number to avoid confusion with standard tape-and-reel packaging specifications.

Crystals Selection Notes

Select this component when a 20 MHz surface-mount crystal with 18pF load capacitance is required. The HC-49/US-SM form factor allows for direct replacement of through-hole HC-49/US crystals in space-constrained designs. Verify that the circuit's external load capacitors match the 18pF specification to maintain the stated ±30ppm frequency tolerance.

Crystals Part Context

This part belongs to the ATS-SM series of surface-mount crystals from CTS-Frequency Controls. It shares the physical dimensions and electrical characteristics of the ATS200CSM-1 but may include specific manufacturing attributes indicated by the 'E' suffix. It serves as a compact alternative to traditional axial-lead crystals for modern PCB layouts.

Crystals Replacement Considerations

ATS200CSM-1 is a direct parameter-equivalent substitute within the same product family.
