Overview
The QT216S-24.000MAHJ-T is a 24 MHz quartz crystal resonator manufactured by QST, designed for surface-mount applications. It features a compact body dimension of 2.0 x 1.6 x 0.5 mm and utilizes a seam seal construction with four ceramic pads. The component operates within a frequency stability of ±30 ppm at 25°C and maintains ±30 ppm across the industrial temperature range of -40°C to +85°C. It is specified with a load capacitance of 18 pF and is supplied in tape and reel packaging.
Feature Summary
- Seam seal construction for enhanced environmental protection
- Compact 4-SMD no-lead package design
- Industrial temperature range operation capability
Applications
- Microcontroller clock inputs
- Digital signal processing circuits
- Communication module timing references
Procurement Notes
Verify the specific load capacitance requirement against the target circuit design, as variants exist with different capacitance values such as 12pF or 10pF. Confirm that the ±30ppm stability meets the system's jitter and accuracy specifications. Ensure the 2.0x1.6mm footprint aligns with the PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a small form factor is required alongside moderate frequency stability. The 18pF load capacitance must match the oscillator circuit design. Consider alternative variants if higher stability or different capacitance values are needed for the specific application environment.
Part Context
This part belongs to the QT216S series of MHz quartz crystals from QST. The series offers various load capacitance options and frequency tolerances while maintaining a consistent 2.0x1.6mm surface-mount footprint suitable for space-constrained electronic designs.
Replacement Considerations
Direct substitutes include other 24MHz crystals with identical 18pF load capacitance and ±30ppm stability in a 2.0x1.6mm SMD package. Verify pin compatibility and thermal characteristics when cross-referencing with other manufacturers' offerings.
