QT252S-26.000MEEE-T

Crystals Overview

The QT252S-26.000MEEE-T is a quartz crystal oscillator manufactured by TXC Corporation, designed for precision timing applications. It operates at a fundamental frequency of 26.000 MHz and utilizes a seam seal package with dimensions of 2.5x2.0 mm. The component features four surface-mount pads and incorporates a ceramic construction to ensure mechanical stability and environmental resistance. Frequency tolerance is specified at +/-10 ppm at 25°C and +/-10 ppm across the extended temperature range of -30°C to +85°C. The load capacitance is rated at 9 pF, making it suitable for integration into compact electronic circuits requiring stable clock signals.

Crystals Feature Summary

• Seam seal construction provides robust protection against environmental contaminants and physical stress
• High frequency stability maintained across wide operating temperature ranges
• Compact surface-mount footprint facilitates automated assembly in dense PCB layouts

Crystals Applications

• Clock generation for microprocessors and microcontrollers
• Timing reference for communication interfaces such as UART and SPI
• Frequency control in consumer electronics and industrial control systems

Crystals Procurement Notes

Verify that the specific suffix MEEE-T matches the required load capacitance and temperature tolerance specifications for your design. Confirm package compatibility with your pick-and-place equipment capabilities. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet prior to soldering. Cross-reference the manufacturer's latest documentation to confirm end-of-life status or recommended replacement parts if applicable.

Crystals Selection Notes

Select this component when a 26 MHz reference is required within a 2.5x2.0 mm envelope. Consider the +/-10 ppm tolerance sufficient for standard digital logic timing. Evaluate the 9 pF load capacitance against the oscillator circuit requirements. Assess thermal performance needs against the -30°C to +85°C operational range provided by the specification.
