QT216S-27.120MAHE-T

Overview

The QT216S-27.120MAHE-T is a surface-mount quartz crystal resonator manufactured by QST Products. It operates at a nominal frequency of 27.12 MHz with a frequency stability and tolerance of ±30 ppm. The component features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 90 Ohms. It utilizes a seam seal package construction within a compact 4-SMD, No Lead footprint measuring 2.0 mm x 1.6 mm x 0.5 mm. The device supports fundamental mode operation and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

Seam seal construction for enhanced environmental protection
Compact 4-SMD no-lead surface mount design
Fundamental mode quartz crystal operation

Applications

Clock signal generation in microcontroller circuits
Frequency reference for communication modules
Timing sources for embedded systems

Procurement Notes

Verify the specific suffix HE against official QST documentation to confirm package dimensions and sealing type. Ensure compatibility with PCB soldering profiles for 4-SMD components. Cross-reference the manufacturer part number with authorized distributor databases to confirm current production status and RoHS compliance details before finalizing procurement plans.

Selection Notes

Select this component when a 27.12 MHz timing source is required in space-constrained designs. The 12 pF load capacitance must match the oscillator circuit requirements. Consider the ±30 ppm stability for applications requiring moderate precision. Verify that the -40°C to +85°C temperature range meets the operational environment specifications of the target electronic assembly.
