QT252G-24.576MAHE-T

Overview

The QT252G-24.576MAHE-T is a quartz crystal resonator manufactured by QST Products, designed for surface-mount applications. It operates at a fundamental frequency of 24.576 MHz with a load capacitance of 8 pF. The component features a standard tolerance and stability of ±30 ppm across the commercial temperature range of -20°C to +70°C. It utilizes a 4-SMD, No Lead package with dimensions of 2.5 mm x 2.0 mm, suitable for automated assembly processes in compact electronic designs.

Feature Summary

• Fundamental mode quartz crystal operation providing stable frequency reference
• Surface-mount design compatible with automated pick-and-place manufacturing
• Compact footprint optimized for space-constrained printed circuit board layouts

Applications

• General-purpose clock generation for microcontrollers
• Timing references for digital communication interfaces
• Frequency standards for consumer electronics devices

Procurement Notes

Verify the specific suffix HE-T against official QST documentation to confirm package type and tape/reel specifications. Ensure the requested frequency matches the design requirement exactly, as minor variations exist within the series. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and lead times prior to ordering.

Selection Notes

Select this component when a 24.576 MHz fundamental frequency is required with ±30 ppm stability. The 8 pF load capacitance must match the oscillator circuit design. Consider the -20°C to +70°C operating range suitability for the intended environment. Evaluate the 4-SMD no-lead package constraints against PCB layout guidelines for thermal and mechanical reliability.

Part Context

This part belongs to the QT252G series of quartz crystals from QST Products. The series offers various frequencies within a standardized 2.5mm x 2.0mm SMD form factor. Components in this family share similar electrical characteristics and mounting requirements, differing primarily in frequency and specific suffix codes that denote packaging or minor parameter variations.

Replacement Considerations

QT252G-24.576MEEV-T is listed as a related variant in public records. Verify pin compatibility and exact electrical parameters before substitution. Other manufacturers may offer equivalent 24.576 MHz crystals in 4-SMD packages, but require full validation of load capacitance and stability specs.
