QT252S-24.000MAHE-T

Overview

The QT252S-24.000MAHE-T is a quartz crystal resonator manufactured by QST Products, LLC. It operates at a fundamental frequency of 24 MHz with a load capacitance of 12 pF. The component features a surface-mount package measuring 2.5 x 2.0 x 0.55 mm. Frequency stability is rated at ±30 ppm across the operating temperature range of -40°C to +85°C. The device utilizes a seam seal construction with four pads and ceramic materials.

Feature Summary

• Seam seal construction for environmental protection
• Surface-mount design with four-pad configuration
• Wide operating temperature range capability

Applications

• Clock signal generation in microcontroller circuits
• Timing reference for communication interfaces
• Frequency control in consumer electronic devices

Procurement Notes

Verify the manufacturer designation carefully, as this specific part number is associated with QST Products, LLC, while similar identifiers may appear under TXC Corporation listings. Confirm the suffix HE-T corresponds to the specified 12 pF load capacitance and ±30 ppm stability. Ensure compatibility with the required 2.5x2.0 mm footprint and seam seal technology before integration into the final assembly.

Selection Notes

Select this component when a compact 24 MHz timing source is required with moderate stability over a wide industrial temperature range. The 12 pF load capacitance must match the oscillator circuit design specifications. Consider the physical dimensions and surface-mount orientation for PCB layout constraints. Verify that the ±30 ppm tolerance meets the system's clock accuracy requirements.

Part Context

This component belongs to the QT252S series of quartz crystals. The series offers various frequency options and stability grades within a standardized small outline package. The specific model defines the electrical parameters including frequency, load capacitance, and temperature coefficient. It serves as a passive frequency-determining element in active oscillator circuits.

Replacement Considerations

Direct substitutes include other 24 MHz crystals with identical 2.5x2.0 mm dimensions, 12 pF load capacitance, and ±30 ppm stability. Cross-reference part numbers such as those from Murata or other manufacturers offering equivalent SMD quartz resonators. Ensure the replacement maintains the same package type and terminal configuration.
