QT532S-28.63636MEEQ-T

Overview

The QT532S-28.63636MEEQ-T is a surface-mount quartz crystal resonator manufactured by QST. It operates at a fundamental frequency of 28.63636MHz with a load capacitance of 10pF. The component exhibits a frequency tolerance and stability of ±10ppm at 25°C and across the operating temperature range of -20°C to +70°C. Its equivalent series resistance (ESR) is specified as 40Ω. The device utilizes a seam seal ceramic package with four solder pads, measuring 5.0mm x 3.2mm x 0.9mm.

Feature Summary

Seam sealed ceramic construction for environmental protection
Surface mount design with four solder pads
High frequency stability within specified temperature ranges

Applications

Avionics systems
Navigation systems
Radar systems
Communication systems

Procurement Notes

Verify the specific manufacturer designation, as the model number references QST but datasheets may list TXC Corporation. Confirm the exact package dimensions and pin configuration against the official data sheet before integration. Ensure the operating temperature range meets the application requirements. Validate the frequency tolerance specifications for the target environment.

Selection Notes

Select this component when a precise 28.63636MHz reference is required in space-constrained designs. The 5x3.2mm footprint suits compact PCB layouts. Consider the ±10ppm stability requirement for clock generation circuits. The 40Ω ESR must be compatible with the oscillator circuit's drive level constraints.

Part Context

This part belongs to the QT532S series of surface-mount quartz crystals. The series offers various frequencies while maintaining consistent physical dimensions and electrical characteristics. Similar models include variants with different frequencies such as 24.576MHz or 36.000MHz, sharing the same package and general performance profile.

Replacement Considerations

Direct substitutes may include other manufacturers' 28.63636MHz crystals in 5032 packages. Verify compatibility regarding load capacitance and ESR values. Cross-reference with TXC Corporation equivalents if supply chain diversification is necessary.
