QT49S-10.000MAAJ-T

Overview

The QST QT49S-10.000MAAJ-T is a surface-mount quartz crystal resonator operating at a nominal frequency of 10 MHz. It features an HC-49/US-style SMD package with dimensions of 11.4 x 4.35 x 3.8 mm and utilizes a 4-SMD, no-lead configuration. The component supports a load capacitance of 18 pF and maintains a frequency stability of ±30 ppm. It operates within a temperature range of -40°C to +85°C, ensuring reliable performance in consumer electronics applications requiring stable clock signals.

Feature Summary

• Standardized SMD form factor compatible with automated pick-and-place assembly processes
• Stable frequency generation for digital circuit timing requirements
• Wide operational temperature range suitable for diverse environmental conditions

Applications

• Consumer electronic device clock sources
• Microcontroller system timing references
• General-purpose digital logic circuits

Procurement Notes

Verify the specific package dimensions against the target PCB footprint prior to integration. Confirm that the 18 pF load capacitance aligns with the oscillator circuit design parameters. Ensure the ±30 ppm frequency tolerance meets the system's timing accuracy requirements. Check for RoHS compliance documentation if required by regulatory standards. Validate supplier authenticity through authorized distribution channels.

Selection Notes

Select this component when a standard HC-49/US footprint is required in a surface-mount format. It is appropriate for designs where ±30 ppm stability is sufficient for the application. Consider the physical size constraints of the 11.4 x 4.35 mm body. Evaluate the operating temperature range against the intended deployment environment. Compare against alternative SMD crystals if tighter tolerance or different packaging is needed.

Part Context

This part belongs to the QST series of surface-mount quartz crystals. It serves as a direct surface-mount replacement for traditional through-hole HC-49/US crystals. The MA suffix typically indicates specific terminal plating or packaging variations common in SMD variants. It is designed for high-volume manufacturing environments requiring consistent frequency performance.
