QT325G-26.000MEIV-T

Overview

The QT325G-26.000MEIV-T is a quartz crystal resonator manufactured by QST Products, LLC. It operates at a fundamental frequency of 26 MHz with a normal temperature frequency tolerance of ±10 ppm and an overall frequency stability of ±30 ppm. The component features a load capacitance of 8 pF and an equivalent series resistance (ESR) of 60 Ohms. It utilizes a glass seal construction within a 3.2 x 2.5 mm surface-mount package. The device supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Glass seal construction for enhanced environmental stability
• Surface-mount design in a compact 3.2x2.5mm footprint
• High frequency stability with ±10 ppm initial tolerance

Applications

• Clock signal generation for microprocessors
• Timing references for communication modules
• Frequency control in consumer electronics

Procurement Notes

Verify the specific suffix MEIV against official QST documentation to confirm the exact electrical parameters and packaging configuration. Ensure compatibility with the target circuit's load capacitance requirements. Cross-reference the manufacturing date code and RoHS compliance status with current supplier declarations to meet regulatory standards.

Selection Notes

Select this component when a 26 MHz reference with high stability is required in a space-constrained application. The 8pF load capacitance must match the oscillator circuit design. Consider the ±30 ppm total stability over the full temperature range for precision timing needs. The glass seal offers superior performance compared to standard epoxy-sealed alternatives.
