QT532G-13.560MAAE-T

Overview

The QT532G-13.560MAAE-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a nominal frequency of 13.56 MHz with a frequency tolerance of ±30 ppm at 25°C and ±30 ppm over the temperature range of -20°C to +70°C. The component features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 50 Ohms. It utilizes a glass-sealed package construction in a 2-SMD, No Lead form factor with dimensions of 5.0 x 3.2 x 1.2 mm.

Feature Summary

• Glass-sealed quartz crystal construction for enhanced stability
• Surface-mount design compatible with automated assembly processes
• Optimized for RFID and NFC operating frequencies

Applications

• Radio Frequency Identification (RFID) systems
• Near Field Communication (NFC) devices
• Contactless smart card readers

Procurement Notes

Verify the specific suffix 'AAE' against manufacturer documentation to confirm the exact load capacitance and package variant, as suffixes often denote critical electrical or mechanical differences. Ensure the supplier provides traceability to QST manufacturing standards. Cross-reference the datasheet for storage conditions and soldering profiles to maintain component integrity during procurement and handling.

Selection Notes

Select this component when a stable 13.56 MHz reference is required for contactless communication interfaces. The ±30 ppm tolerance suits standard RFID/NFC applications where high precision is not critical. Consider the 12 pF load capacitance compatibility with the host oscillator circuit. Evaluate the 50 Ohm ESR against driver strength requirements to ensure reliable oscillation start-up.

Part Context

This part belongs to the QT532G series of quartz crystals from QST, which are engineered for compact electronic designs. The series offers various frequency options within the MHz range, utilizing a standardized 5.0x3.2mm footprint. These components are typically used in consumer electronics and industrial control systems requiring precise timing references in small form factors.

Replacement Considerations

Compatible substitutes include the QT532G-13.560MAAV-T and QT532G-13.560MAHJ-T. Verify that alternative parts match the 13.56 MHz frequency, ±30 ppm tolerance, and 12 pF load capacitance. Note that different suffixes may indicate variations in load capacitance (e.g., 8pF or 18pF) or package type, requiring circuit adjustment if parameters differ.
