QT216S-30.000MAHV-T

Overview

The QT216S-30.000MAHV-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a nominal frequency of 30 MHz with a load capacitance of 8 pF. The component features a frequency stability and resonator tolerance of ±30 ppm at 25°C, maintaining ±30 ppm across the industrial temperature range of -40°C to +85°C. It utilizes a 4-SMD, No Lead package with body dimensions of 2.0 x 1.6 x 0.5 mm. This device is suitable for high-stability timing requirements in compact electronic designs.

Feature Summary

• Compact 2.0x1.6mm surface-mount footprint for space-constrained PCB layouts
• High frequency stability of ±30 ppm across the full industrial temperature range
• Lead-free construction compliant with RoHS standards

Applications

• Embedded communication systems requiring precise clock signals
• Microcontroller unit (MCU) clock sources
• High-power motor control cabinets

Procurement Notes

Verify the specific suffix HV against official QST documentation to confirm pin configuration and loading capacitance specifications. Ensure the selected variant matches the required 8pF load capacitance and 30MHz frequency for your circuit design. Cross-reference the datasheet for reflow soldering profiles to guarantee reliability during assembly processes.

Selection Notes

Select this component when a small form factor is critical alongside strict frequency stability requirements. The 8pF load capacitance must align with the oscillator circuit's input capacitance to ensure accurate frequency generation. Consider the -40°C to +85°C operating range to verify suitability for the intended environmental conditions of the final product.

Part Context

This part belongs to QST's QT216S series of ultra-small quartz crystals. The series is characterized by its miniature 2.0x1.6mm package size, which facilitates high-density mounting on printed circuit boards. These components are engineered to provide reliable timing solutions for modern portable and industrial electronics where space is limited.

Replacement Considerations

Direct substitutes include other 30MHz crystals with identical 2.0x1.6mm dimensions and 8pF load capacitance. Verify that alternative manufacturers offer matching ±30ppm stability across the -40°C to +85°C range. Ensure the replacement part supports the same SMD no-lead package type for compatible footprints.
