QT49S-10.000MAGI-T

Overview

The QST QT49S-10.000MAGI-T is a surface-mount crystal resonator operating at a fundamental frequency of 10 MHz. It utilizes an HC49 package form factor with dimensions of 11.4x4.35x3.8mm. The component features a load capacitance of 16pF and offers frequency stability options of ±30ppm or ±50ppm. Designed for robust performance, it supports an operating temperature range from -40°C to +85°C. This SMD variant provides reliable timing solutions for compact electronic designs requiring precise clock signals.

Feature Summary

• Surface mount construction for automated assembly
• Fundamental operating mode for stable oscillation
• HC49 compatible physical footprint

Applications

• Microcontroller clock sources
• Communication module timing
• Digital circuit synchronization

Procurement Notes

Verify the specific frequency tolerance required for your design, as datasheets indicate availability in both ±30ppm and ±50ppm variants under this part number. Confirm that the 16pF load capacitance matches your oscillator circuit requirements. Ensure the surface mount package dimensions fit within your PCB layout constraints. Cross-reference the RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a standard HC49 footprint is needed in a surface-mount configuration. The 10MHz frequency is common for general-purpose timing applications. Consider the ±30ppm or ±50ppm stability based on the precision requirements of the target system. The wide operating temperature range suits industrial or consumer electronics environments.

Part Context

This crystal belongs to the QST QT49S series of surface-mount resonators. It serves as a direct replacement for through-hole HC49/U crystals where space savings are critical. The series maintains consistent electrical characteristics while adapting the mechanical interface for modern PCB technologies.

Replacement Considerations

Direct substitutes include other manufacturers' HC49 SMD crystals with identical 10MHz frequency, 16pF load capacitance, and matching ±30ppm or ±50ppm tolerances. Verify pin compatibility and mounting orientation when swapping brands.
