QT532S-13.560MEEQ-T

Overview

The QT532S-13.560MEEQ-T is a surface-mount quartz crystal resonator manufactured by TXC Corporation, distributed under the QST brand. It operates at a fundamental frequency of 13.56 MHz with a load capacitance of 10 pF and an equivalent series resistance of 40 Ohms. The component features a 4-pin SMD package with no leads, measuring 5.0 x 3.2 x 0.9 mm. Frequency stability is specified at ±10 ppm from -20°C to +70°C and ±10 ppm at 25°C.

Feature Summary

• Seam seal construction for environmental protection
• Surface mount design for automated assembly
• High frequency stability across operating temperature range

Applications

• RFID reader circuits
• Wireless communication modules
• Industrial control systems requiring precise timing

Procurement Notes

Verify the manufacturer designation on the datasheet, as this part is produced by TXC Corporation and sold by distributors like QST. Confirm the specific ordering suffix matches the required frequency tolerance and load capacitance. Ensure the package dimensions align with the PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a 13.56 MHz reference is required for RFID or ISM band applications. The 40 Ohm ESR suits standard oscillator circuits. Consider the ±10 ppm stability if tight frequency accuracy is needed over the industrial temperature range. Verify that the 10 pF load capacitance matches the oscillator circuit design specifications.

Part Context

This part belongs to the QT532S series of seam-seal quartz crystals. Similar variants in the series include different frequencies such as 8 MHz, 12 MHz, 32 MHz, and 36 MHz, all sharing the same 5x3.2mm SMD package and general electrical characteristics.

Replacement Considerations

Direct substitutes within the same series include QT532S-8.000MEEQ-T, QT532S-12.000MEEQ-T, QT532S-32.000MEEQ-T, and QT532S-36.000MEEQ-T, provided the frequency difference is acceptable for the application.
