QT216S-32.000MEIV-T

Overview

The QST QT216S-32.000MEIV-T is a surface-mount quartz crystal oscillator manufactured by QST Products, LLC. It operates at a fundamental frequency of 32 MHz and utilizes a compact 4-SMD ceramic package with dimensions of 2.0 x 1.6 x 0.5 mm. The component features a load capacitance of 8 pF and exhibits a frequency tolerance of ±10 ppm at 25°C. It supports an operating temperature range of -20°C to +70°C with a stability of ±10 ppm within this range. The equivalent series resistance (ESR) is specified as 120 Ohms.

Feature Summary

• Compact 2.0x1.6mm SMD ceramic package for space-constrained designs
• High frequency stability with ±10 ppm tolerance across the operating temperature range
• Low load capacitance of 8 pF for simplified circuit matching

Applications

• Bluetooth module clock sources
• Wi-Fi communication interfaces
• Mobile device main clocks
• IoT sensor nodes

Procurement Notes

Verify the specific suffix against the official QST datasheet to confirm electrical parameters. Ensure the ordering code matches the required load capacitance and stability specifications. Confirm that the package dimensions align with the PCB footprint requirements before finalizing procurement.

Selection Notes

Select this model when a small form factor is critical alongside precise timing requirements. The 8 pF load capacitance suits controllers requiring low capacitive loading. Verify that the -20°C to +70°C temperature range meets the environmental conditions of the target application.

Part Context

This part belongs to the QT216S series of miniature quartz crystals from QST. The series is designed for applications where board space is limited. The 2.0x1.6mm size offers significant area reduction compared to standard 3225 packages while maintaining reliable performance for digital signal processing.

Replacement Considerations

Direct substitutes must match the 32 MHz frequency, 8 pF load capacitance, and 2.0x1.6mm package. Verify ESR compatibility with the host oscillator circuit. Check if alternative brands offer the same ±10 ppm stability over the identical temperature range.
