• Seam seal construction for environmental protection
• Surface-mount design for automated assembly
• High frequency stability within specified operating temperatures

Applications

• Clock signal generation in digital circuits
• Timing references for microcontrollers
• Communication interface synchronization

Procurement Notes

Verify the manufacturer designation carefully, as this part number appears in catalogs associated with both QST Products, LLC and TXC Corporation. Confirm the specific datasheet version and physical marking to ensure compatibility with your supply chain requirements before finalizing procurement.

Selection Notes

Select this component when a 19.2 MHz reference is required in a compact 2.5x2.0 mm footprint. Ensure the application circuit supports an 18 pF load capacitance. Verify that the -20°C to +70°C temperature range meets the operational environment constraints of the target system.

Part Context

This crystal belongs to the QT252S series, which utilizes seam seal technology to protect the quartz element. The series provides reliable timing solutions for space-constrained electronic designs requiring stable frequency generation without the need for active oscillator components.

Replacement Considerations

Direct substitutes include other 19.2 MHz crystals in 2520 packages with 18 pF load capacitance and ±30 ppm stability. Cross-reference with equivalent parts from manufacturers such as TXC or Epson to ensure pinout and electrical parameter compatibility.
