Overview
The QT216S-30.000MAAV-T is a quartz crystal oscillator manufactured by QST Products, designed for surface-mount applications. It operates at a nominal frequency of 30 MHz with a load capacitance of 8 pF and an equivalent series resistance of 50 Ohms. The component utilizes a seam seal package construction within a compact 2.0 x 1.6 mm footprint. Frequency stability is specified at ±30 ppm at 25°C and ±30 ppm across the industrial temperature range of -20°C to +70°C. This device features a four-pad no-lead SMD configuration suitable for automated assembly processes.
Feature Summary
- Seam seal construction for enhanced environmental protection
- Compact 2.0x1.6 mm surface-mount footprint
- Four-pad no-lead design for automated placement
Applications
- General purpose timing circuits
- Microcontroller clock sources
- Communication module oscillators
Procurement Notes
Verify manufacturer designation as QST Products or TXC Corporation depending on supply chain source. Confirm package dimensions match 2.0x1.6 mm requirements. Ensure load capacitance matches circuit design specifications. Check temperature range compliance for operational environment.
Selection Notes
Select this component when a 30 MHz reference signal is required in space-constrained designs. Consider the 8 pF load capacitance compatibility with host oscillator circuits. Evaluate thermal performance against the -20°C to +70°C specification limits. Compare physical size constraints against alternative crystal packages.
Part Context
This part belongs to the QT216S series of miniature quartz crystals. The series offers various frequency options within the same mechanical envelope. Similar parts include variants with different frequencies such as 16 MHz or 38.4 MHz while maintaining identical package and electrical characteristics.
Replacement Considerations
Direct substitutes may include other manufacturers offering 30 MHz crystals in 2.0x1.6 mm seam seal packages. Verify pinout compatibility and electrical parameters before substitution.
