QT532G-13.560MAHJ-T

Overview

The QT532G-13.560MAHJ-T is a quartz crystal resonator manufactured by QST, operating at a nominal frequency of 13.56 MHz. It features a frequency tolerance of ±30 ppm across standard temperature ranges and utilizes a load capacitance of 18 pF with a motional resistance of 50 Ohms. The component is housed in a compact 2-SMD, No Lead package with dimensions of 5.0x3.2 mm, designed for surface-mount assembly in high-reliability timing applications.

Feature Summary

• Provides stable 13.56 MHz oscillation for RFID and NFC systems
• Compact 2-SMD no-lead package design for space-constrained PCBs
• High reliability construction suitable for industrial environments

Applications

• Radio Frequency Identification (RFID) readers
• Near Field Communication (NFC) devices
• Human Machine Interface (HMI) modules
• Programmable Logic Controller (PLC) clock sources

Procurement Notes

Verify the specific suffix MAHJ-T against official QST documentation to confirm package type and tolerance specifications. Ensure compatibility with existing PCB footprints for 2-SMD no-lead components. Cross-reference datasheets for thermal performance limits before integration into final assemblies.

Selection Notes

Select this component when a precise 13.56 MHz reference is required for wireless communication standards. The 18 pF load capacitance must match the oscillator circuit design. Consider the ±30 ppm tolerance for system-level frequency budget calculations in critical timing applications.

Part Context

This part belongs to the QT532G series of quartz crystals from QST. The series offers various frequencies and packages, with this specific model targeting the 13.56 MHz ISM band. It serves as a fundamental timing element for digital circuits requiring accurate clock signals.

Replacement Considerations

Direct substitutes include other 13.56 MHz crystals with identical 18 pF load capacitance and 50 Ohm ESR. Verify pinout and dimensional compatibility for 5.0x3.2 mm SMD packages before substitution.
