ATS240-E

Crystals Overview

The ATS240-E is a 24 MHz fundamental mode crystal oscillator manufactured by CTS-Frequency Controls. It operates within the HC-49/US through-hole package configuration, designed for standard surface mounting applications. The component exhibits a frequency tolerance of ±30 ppm and a stability rating of ±50 ppm across specified temperature ranges. Key electrical parameters include an equivalent series resistance (ESR) of 30 Ohms and a load capacitance defined in series resonance mode. This unit provides reliable frequency generation for digital circuits requiring precise timing references.

Crystals Feature Summary

• HC-49/US through-hole package for standard PCB mounting
• Series resonance design with low equivalent series resistance

Crystals Applications

• Microcontroller clock sources
• Digital communication interfaces
• Timing reference for embedded systems

Crystals Procurement Notes

Verify the specific suffix codes against the official CTS datasheet to ensure correct load capacitance and tolerance specifications. Confirm that the HC-49/US package dimensions align with your PCB footprint requirements. Check the operating temperature range to ensure compatibility with your environmental conditions. Ensure the supplier provides genuine CTS-Frequency Controls products to guarantee performance reliability.

Crystals Selection Notes

Select this component when a 24 MHz fundamental frequency is required with ±30 ppm initial tolerance. Consider the 30 Ohm ESR value for circuit impedance matching. The HC-49/US package is suitable for manual or wave soldering processes. Evaluate the ±50 ppm stability requirement against your system's timing accuracy needs before finalizing the part number selection.

Crystals Part Context

The ATS240-E belongs to the ATS(-SM) series of crystals from CTS-Frequency Controls. This series focuses on general-purpose timing applications using fundamental mode quartz resonators. The ATS240 variant specifically targets the 24 MHz frequency band, widely used in computing and communication hardware. The product line emphasizes consistency in electrical characteristics across the series.

Crystals Replacement Considerations

Direct substitutes may include other 24 MHz HC-49/US crystals with similar ±30 ppm tolerance and 30 Ohm ESR. Verify pin compatibility and mechanical dimensions before swapping manufacturers. Cross-reference load capacitance requirements if the original circuit design is sensitive to capacitive loading changes.
