Procurement Notes

Verify the manufacturer designation carefully, as this specific part number may be associated with QST or TXC Corporation depending on the supply chain source. Confirm that the suffix 'HJ' corresponds to the required packaging and tape-and-reel specifications. Ensure the requested unit matches the 11.0592 MHz frequency and ±30 ppm tolerance requirements for your specific circuit design before finalizing the order.

Selection Notes

Select this component when a 11.0592 MHz reference is required for serial communication interfaces such as UART, which benefit from this specific baud-rate generating frequency. The ±30 ppm tolerance is suitable for most standard asynchronous communication protocols. Consider the 18 pF load capacitance requirement to ensure compatibility with the oscillator circuit's internal capacitors. The wide temperature range makes it appropriate for automotive and industrial environments where thermal stability is critical.

Part Context

This component belongs to the QT532G series of surface-mount quartz crystals. The series offers various frequency options and tolerance grades, with the 'G' suffix indicating a ±50 ppm tolerance option in some variants, though this specific model specifies ±30 ppm. The 5x3.2mm form factor is common for space-constrained designs. Similar parts in the series may differ in aging rates or specific temperature coefficients, so checking the full datasheet is recommended for critical timing applications.

Replacement Considerations

Direct substitutes include other manufacturers offering 11.0592 MHz crystals in 5.0x3.2mm SMD packages with 18 pF load capacitance and ±30 ppm tolerance. Verify that alternative parts meet the same series resistance and aging specifications. Cross-reference part numbers from suppliers like TXC Corporation if sourcing from different distributors, ensuring the electrical characteristics remain identical for seamless integration.
