QT216G-26.000MDDB-T

Overview

The QST QT216G-26.000MDDB-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 26 MHz. It features a compact 2.0 x 1.6 mm package with a height of 0.6 mm, designed for space-constrained applications. The component exhibits a frequency stability of ±20 ppm and utilizes a load capacitance of 6 pF. It operates within a temperature range of -20°C to +70°C and has an equivalent series resistance (ESR) of 150 ohms.

Feature Summary

• Compact 2.0x1.6mm SMD footprint suitable for high-density PCB layouts
• Glass seal construction for environmental protection
• Fundamental mode operation at 26 MHz
• Standard 6pF load capacitance compatibility

Applications

• Microcontroller clock sources
• Communication module timing references
• Consumer electronics control circuits
• Industrial sensor interfaces

Procurement Notes

Verify the manufacturer designation as QST against the specific part number QT216G-26.000MDDB-T. Confirm that the load capacitance requirement matches the circuit design's 6pF specification. Ensure the operating temperature range of -20°C to +70°C aligns with the target application environment. Check for RoHS compliance status in the official datasheet before finalizing procurement.

Selection Notes

Select this component when a 26 MHz reference is required in a minimal footprint. The 6pF load capacitance must match the oscillator circuit's external capacitors. Consider the ±20 ppm stability for general-purpose timing rather than high-precision navigation. The glass seal offers basic protection compared to ceramic packages.

Part Context

This part belongs to the QT216G series of surface-mount crystals from QST. These components are designed as drop-in replacements for larger through-hole crystals in modern electronics. The series emphasizes miniaturization while maintaining standard electrical parameters for common microcontroller and communication applications.

Replacement Considerations

Direct substitutes must match the 26 MHz frequency, 6pF load capacitance, and 2.0x1.6mm package dimensions. Verify that alternative manufacturers offer the same ±20 ppm stability and ESR characteristics. Ensure the replacement supports the same soldering profile and reflow temperature limits.
