QT325G-26.000MAGV-T

Overview

The QT325G-26.000MAGV-T is a surface-mount crystal oscillator manufactured by QST, designed for precision timing applications. It operates at a fundamental frequency of 26 MHz with a load capacitance of 8 pF and an equivalent series resistance (ESR) of 60 Ohms. The component features a frequency tolerance of ±30 ppm and a frequency stability of ±50 ppm over the operating temperature range of -40°C to +85°C. It utilizes a 4-SMD, No Lead package with dimensions of 3.2 mm x 2.5 mm x 0.9 mm max height.

Feature Summary

• Provides stable oscillation at 26 MHz with high frequency accuracy
• Supports surface mount assembly via a compact 4-SMD no lead package
• Operates reliably across industrial temperature ranges from -40°C to +85°C

Applications

• Clock generation for microcontrollers and digital signal processors
• Timing reference in communication modules requiring 26 MHz signals
• Embedded systems utilizing surface mount technology constraints

Procurement Notes

Verify that the specific suffix MAGV corresponds to the required 8 pF load capacitance and ±30 ppm tolerance, as other suffixes in the QT325G series may indicate different electrical parameters such as 10 pF or 12 pF load capacitance. Confirm AEC-Q200 qualification if automotive grade reliability is mandated for the target application environment.

Selection Notes

Select this component when a 26 MHz fundamental frequency crystal is required with strict size limitations fitting within a 3.2mm x 2.5mm footprint. Ensure the circuit design accounts for an 8 pF load capacitance and 60 Ohm ESR to maintain the specified ±30 ppm frequency tolerance. Consider the -40°C to +85°C operating range against environmental conditions.

Part Context

This part belongs to the QT325G series of quartz crystals from QST, which are characterized by their small form factor suitable for dense PCB layouts. The series offers various load capacitance options differentiated by suffix codes, allowing designers to match specific oscillator circuit requirements without altering the physical package dimensions.

Replacement Considerations

Direct substitutes include other manufacturers' 26 MHz crystals in 3225 packages with identical 8 pF load capacitance and similar ESR values. Cross-reference datasheets to ensure compatible drive level specifications and aging rates before substitution.
