Applications

• Microcontroller clock sources
• Communication module timing references
• Consumer electronics oscillator circuits

Procurement Notes

Verify the manufacturer designation on official documentation, as some listings attribute this part to TXC Corporation while others list QST. Confirm the specific suffix MAHJ-T matches the required 8 MHz frequency and 18 pF load capacitance specifications. Ensure compliance with RoHS standards if required by your manufacturing process. Cross-reference datasheets from authorized distributors to confirm active status and availability before procurement.

Selection Notes

Select this component when a fundamental mode crystal with ±30 ppm stability is required for 8 MHz applications. The 18 pF load capacitance must match the oscillator circuit design. Consider the 80 Ohm series resistance for drive level sensitivity. The SMD package size fits standard footprint requirements for compact boards. Verify temperature range compatibility with the operational environment.

Part Context

This part belongs to the QT532S series of surface-mount crystals. Variants within this series differ primarily by frequency and load capacitance values while sharing similar physical dimensions and electrical characteristics. The MAHJ-T suffix indicates specific packaging and termination details. Similar parts include the QT532S-12.000MAHJ-T for 12 MHz applications.

Replacement Considerations

Direct substitutes may include other 8 MHz crystals with identical 18 pF load capacitance and ±30 ppm stability. Check pinout compatibility for 4-pin SMD packages. Ensure equivalent series resistance and power handling capabilities. Verify that alternative manufacturers offer the same temperature stability range.
