QT252S-25.000MAHE-T

Overview

The QT252S-25.000MAHE-T is a surface-mount quartz crystal manufactured by QST, operating at a nominal frequency of 25 MHz. It utilizes a 4-SMD, No Lead package with dimensions of 2.5 mm x 2.0 mm. The component exhibits a frequency tolerance and stability of ±30 ppm at 25°C and across the -40°C to +85°C temperature range. It features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 100 Ohms. The device is RoHS compliant and designed for reliable clock signal generation in electronic circuits.

Feature Summary

Seam seal construction for environmental protection
Surface mount design for automated assembly
Wide industrial temperature operation capability

Applications

Microcontroller clock sources
Communication module timing
Digital circuit synchronization

Procurement Notes

Verify manufacturer authenticity through official channels. Confirm RoHS compliance status matches current regulatory requirements. Validate package dimensions against PCB footprint specifications. Ensure storage conditions prevent moisture absorption prior to soldering. Cross-reference datasheet revisions for any parameter updates.

Selection Notes

Evaluate thermal stability requirements against the specified ±30 ppm tolerance. Consider load capacitance compatibility with the target oscillator circuit. Assess physical space constraints relative to the 2.5x2.0 mm package size. Review ESR limits for power consumption efficiency. Confirm operating temperature range aligns with environmental conditions.

Part Context

This component belongs to the QT252S series of surface-mount crystals from QST. The series offers various frequency options within a compact form factor. These devices are engineered for high reliability in consumer and industrial electronics. The specific model denotes a 25 MHz variant with standard stability parameters.

Replacement Considerations

Direct substitutes include other 25 MHz SMD crystals with identical 2.5x2.0 mm packages and ±30 ppm stability. Verify pinout compatibility and load capacitance matching. Check equivalent series resistance values for circuit performance parity.
