QT49S-28.63636MAAE-T

Overview

The QT49S-28.63636MAAE-T is a quartz crystal resonator manufactured by QST Products, LLC. It operates at a fundamental frequency of 28.63636 MHz with a load capacitance of 12 pF and an equivalent series resistance (ESR) of 30 Ohms. The component provides a frequency tolerance of ±30 ppm at 25°C and maintains stability within ±30 ppm across the operating temperature range of -20°C to +70°C. It utilizes the HC-49/US package style for through-hole mounting.

Feature Summary

Fundamental mode operation for precise frequency generation
HC-49/US package design for standard through-hole integration
Stable performance across industrial temperature ranges

Applications

Microcontroller clock sources
Communication interface timing circuits
Digital signal processing systems

Procurement Notes

Verify the manufacturer designation as QST Products, LLC, distinct from TXC Corporation equivalents. Confirm the package type is HC-49/US rather than surface mount variants. Ensure the ESR specification matches the 30 Ohm requirement for circuit compatibility. Check RoHS compliance status for environmental regulations. Validate the frequency tolerance aligns with system timing requirements.

Selection Notes

Select this component when a fundamental mode crystal with HC-49/US packaging is required. Compare ESR values against oscillator circuit capabilities to ensure proper startup. Verify load capacitance matching with circuit design parameters. Consider temperature stability requirements for the specific application environment. Ensure frequency accuracy meets system synchronization needs.
