ATSM-49-R 6.144000

Overview

The MtronPTI ATSM-49-R 6.144000 is a surface mount fundamental quartz crystal operating at a nominal frequency of 6.144 MHz. It utilizes an AT-cut resonator housed in a package measuring 11.10 mm in length and 4.83 mm in width. The component features a load capacitance of 18 pF and a maximum series resistance of 100 Ohms. Frequency tolerance is specified at ±30 ppm, with stability rated at ±50 ppm. The device supports a drive level of 100 µW and exhibits aging characteristics of 5 ppm per year.

Feature Summary

• Surface mount design for automated assembly processes
• AT-cut quartz resonator technology for stable oscillation
• RoHS compliant manufacturing standards

Applications

• General purpose clock signal generation
• Microcontroller oscillator circuits
• Communication interface timing references

Procurement Notes

Verify the specific frequency suffix matches the required 6.144 MHz specification during ordering. Confirm package dimensions align with PCB footprint requirements. Ensure compliance with RoHS directives if applicable to the target market. Review datasheet for storage temperature limits and soldering profile recommendations to prevent mechanical stress on the crystal element.

Selection Notes

Select this component when a 6.144 MHz fundamental frequency is required in a compact surface mount form factor. Consider the 18 pF load capacitance compatibility with the host circuit's oscillator configuration. Evaluate the ±30 ppm tolerance against system timing accuracy requirements. Assess the 100 µW drive level suitability for the intended application power constraints.

Part Context

This part belongs to the ATSM-49-R series of surface mount crystals from MtronPTI. The series offers various frequency options within a standardized small outline package. These components are designed as direct replacements for through-hole HC-49/U crystals in space-constrained designs while maintaining similar electrical performance characteristics for standard oscillator applications.

Replacement Considerations

Direct replacement requires matching the 6.144 MHz frequency, 18 pF load capacitance, and physical footprint. Verify that the substitute component meets or exceeds the ±30 ppm tolerance and 100 µW drive level specifications. Ensure the new part maintains RoHS compliance if environmental regulations apply.
