QT252S-26.000METV-T

Overview

The QT252S-26.000METV-T is a quartz crystal resonator manufactured by QST, operating at a nominal frequency of 26 MHz. It features a frequency tolerance and stability of ±10 ppm. The component utilizes an 8 pF load capacitance and exhibits an equivalent series resistance (ESR) of 100 Ohms. Designed for surface-mount applications, it employs a 4-SMD, No Lead package configuration with dimensions of 2.5x2.0x0.55 mm. This device is suitable for circuits requiring precise timing signals within standard commercial temperature ranges.

Feature Summary

• High frequency stability of ±10 ppm ensures reliable clock signal generation
• Compact 4-SMD no-lead package facilitates automated surface-mount assembly
• Low equivalent series resistance supports efficient oscillator circuit design

Applications

• Microcontroller clock sources
• Communication module timing references
• Digital signal processing circuits

Procurement Notes

Verify the specific suffix METV-T against official QST documentation to confirm the exact load capacitance and temperature range specifications. Ensure compatibility with the target PCB footprint and reflow soldering profile. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the 8 pF load capacitance matches the oscillator circuit requirements of the host system.

Selection Notes

Select this component when a 26 MHz frequency with ±10 ppm stability is required for space-constrained designs. The 4-SMD no-lead form factor is ideal for high-density boards. Consider the 100 Ohm ESR value when designing the oscillator circuit to ensure proper startup conditions. Verify that the operating temperature range meets the environmental demands of the final application.

Part Context

This part belongs to the QT252S series of quartz crystals from QST. The series offers various frequency options and stability grades in a standardized small outline package. The QT252S designation indicates a specific mechanical size and pin configuration common across multiple variants in the product line.

Replacement Considerations

Direct substitutes include other 26 MHz crystals with identical 4-SMD no-lead dimensions and 8 pF load capacitance. Verify that replacement parts maintain the ±10 ppm stability and 100 Ohm ESR specifications to ensure circuit performance parity.
