HC49U/N-R 2.097152

Overview

The MtronPTI HC49U/N-R 2.097152 is a parallel fundamental quartz crystal resonator with a nominal frequency of 2.097152 MHz. It utilizes an AT-cut quartz element housed in a surface-mount HC-49 package featuring four gull-wing pins. The component specifies a load capacitance of 18 pF and a maximum series resistance of 600 ohms. Frequency tolerance options include ±30 ppm and ±50 ppm, ensuring stability for precision timing applications.

Feature Summary

• AT-cut quartz construction for stable oscillation
• Surface-mount HC-49 package design
• Gull-wing terminal configuration

Applications

• Communications equipment
• Broadband fixed line access systems

Procurement Notes

Verify RoHS compliance status carefully as documentation indicates non-compliant variants exist for this part number. Confirm specific frequency tolerance requirements against available ±30 ppm or ±50 ppm options. Ensure the selected variant matches the required surface-mount footprint and pin configuration for PCB integration.

Selection Notes

Select based on required frequency tolerance and operating temperature range. Verify compatibility with circuit load capacitance specifications. Consider the physical dimensions of the HC-49 SMD package for board space constraints. Check datasheet for drive level limitations to prevent over-driving the crystal.

Part Context

This component belongs to the HC-49 family of surface-mount crystals manufactured by MtronPTI. These devices are designed for general-purpose clock generation and frequency reference applications where compact mounting is required compared to through-hole alternatives.

Replacement Considerations

Cross-reference with other HC-49 SMD crystals from different manufacturers. Verify matching electrical parameters including frequency, load capacitance, and ESR before substitution.
