QT325G-26.000MAHV-T

Overview

The QST QT325G-26.000MAHV-T is a surface-mount crystal resonator operating at a fundamental frequency of 26 MHz. It features a frequency tolerance and stability of ±30 ppm at 25°C, with a load capacitance of 8 pF and an equivalent series resistance (ESR) of 60 Ohms. The component utilizes a 4-SMD, no-lead package with dimensions of 3.2 x 2.5 mm. It supports an extended operating temperature range from -40°C to +85°C and is supplied in tape and reel packaging for automated assembly processes.

Feature Summary

• Provides stable 26 MHz oscillation with ±30 ppm frequency accuracy
• Designed for surface-mount integration via 4-SMD no-lead configuration
• Operates reliably across industrial temperature ranges from -40°C to +85°C

Applications

• Microcontroller clock sources
• Communication interface timing circuits
• Digital signal processing systems

Procurement Notes

Verify the complete part number including suffixes against official QST documentation to ensure correct frequency, tolerance, and package variant. Confirm RoHS compliance status and specific testing requirements prior to ordering. Cross-reference datasheet specifications with system design constraints to validate electrical performance and thermal characteristics.

Selection Notes

Select this component when a 26 MHz reference with ±30 ppm stability is required for space-constrained designs. The 8 pF load capacitance must match the oscillator circuit design. Ensure the 60 Ohm ESR aligns with the host oscillator's drive level limitations. Verify that the 3.2x2.5 mm footprint fits the PCB layout constraints.

Part Context

This model belongs to the QT325G series of thin-package crystals manufactured by QST. The series offers various frequencies and tolerances within a compact 3.2x2.5 mm form factor. The MAHV suffix typically denotes specific tolerance and temperature range configurations within this product line.

Replacement Considerations

Direct substitutes include other 26 MHz crystals with identical 3.2x2.5 mm SMD packages, 8 pF load capacitance, and ±30 ppm tolerance. Verify ESR compatibility and operating temperature range before substitution.
