Procurement Notes

Verify the specific suffix MAHJ-T against the manufacturer's current datasheet to confirm package dimensions and soldering profile requirements. Ensure that the load capacitance matches the oscillator circuit design specifications. Confirm that the ±30 ppm tolerance aligns with system timing accuracy needs. Request official documentation from authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a 13 MHz reference signal is required with high stability and low ESR. The 18 pF load capacitance must match the external capacitors in the oscillator circuit to achieve accurate frequency output. Consider the 5x3.2 mm footprint for PCB layout constraints. Verify compatibility with the target application's temperature range and vibration requirements prior to integration.

Part Context

This part belongs to the QT532G series of quartz crystals, which are characterized by their small form factor and robust performance. The series offers various frequency options while maintaining consistent electrical parameters such as ESR and load capacitance. These components are widely used in consumer electronics and industrial equipment where space-saving surface-mount solutions are necessary for reliable timing functions.

Replacement Considerations

Direct substitutes include other manufacturers' 13 MHz SMD crystals with identical 18 pF load capacitance and 50 Ohm ESR. Verify pinout compatibility and mechanical dimensions to ensure fitment. Cross-reference with TXC or NDK equivalents if available, ensuring all electrical specifications match exactly to maintain circuit performance.
