QT252S-26.000MEIY-T

Overview

The QT252S-26.000MEIY-T is a quartz crystal oscillator manufactured by TXC Corporation, distributed under the QST brand. It operates at a fundamental frequency of 26 MHz with a load capacitance of 7 pF. The component features a surface-mount package measuring 2.5 x 2.0 mm and a maximum height of 0.55 mm. Frequency tolerance is specified at ±10 ppm at 25°C and ±20 ppm across the -40°C to +85°C temperature range. This seam-seal device provides stable timing signals for electronic circuits requiring precise clock synchronization.

Feature Summary

• Seam-seal construction for enhanced environmental stability
• Compact 2.5x2.0 mm surface-mount footprint
• High precision frequency tolerance within specified temperature ranges

Applications

• High-power motor control cabinets
• Precision timing circuits in industrial electronics
• Embedded systems requiring stable clock sources

Procurement Notes

Verify the manufacturer designation carefully, as this component is produced by TXC Corporation but marketed under the QST brand. Confirm the specific suffix MEIY-T matches the required 7 pF load capacitance and ±10 ppm tolerance specifications. Ensure compatibility with the target PCB footprint dimensions of 2.5 x 2.0 mm before procurement.

Selection Notes

Select this component when a small form factor is critical alongside high-frequency stability. The 26 MHz output suits applications needing precise synchronization without larger through-hole alternatives. Consider the -40°C to +85°C operating range for industrial environments. Verify that the 7 pF load capacitance aligns with the host circuit's design requirements to maintain accurate frequency performance.

Part Context

This part belongs to the QT252S series of quartz crystals, characterized by their compact 2.5x2.0 mm dimensions. The series offers various frequency options and tolerance levels tailored for space-constrained designs. The QT252S-26.000MEIY-T specifically addresses needs for 26 MHz timing with tight accuracy standards in modern electronic assemblies.

Replacement Considerations

Direct substitutes include other 26 MHz crystals with identical 2.5x2.0 mm packages and 7 pF load capacitance. Verify that alternative parts match the ±10 ppm @ 25°C and ±20 ppm @ -40 to 85°C tolerance specifications. Ensure the replacement maintains the same seam-seal construction and pin configuration for seamless integration.
