The component features an equivalent series resistance (ESR) of 60 Ohms and belongs to the HC49/4HSMX series. It supports base harmonic operation within a temperature range of -10°C to +60°C. The physical package is HC-49/US, measuring 11.30 mm in length, 4.70 mm in width, and up to 4.50 mm in height.

Feature Summary

• Surface mount design utilizing HC-49/US package geometry
• Fundamental mode operation for stable timing signals
• Optimized for commercial-grade environmental conditions

Applications

• Microcontroller clock sources
• Digital communication interfaces
• General-purpose timing circuits

Procurement Notes

Verify the specific ordering suffix required for your production needs, as packaging options such as bulk or tape and reel may vary. Confirm that the HC-49/US footprint matches your PCB layout constraints. Ensure the 30 pF load capacitance aligns with your circuit design requirements before finalizing procurement.

Selection Notes

Select this component when a standard 7.3728 MHz frequency is required for SMD assembly. The HC-49/US form factor offers robust mechanical stability compared to smaller packages. Consider the ±30 ppm tolerance sufficient for general digital logic timing where high precision is not critical.

Part Context
