QT325G-25.000MAAV-T

Overview

The QT325G-25.000MAAV-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a fundamental frequency of 25 MHz with a load capacitance of 8 pF and a frequency stability of ±30 ppm. The component features a compact 3.2 mm x 2.5 mm x 0.8 mm package footprint and utilizes a four-terminal SMD no-lead configuration. This device is engineered to provide reliable timing signals in electronic circuits requiring precise clock synchronization.

Feature Summary

• Surface-mount design with a four-terminal no-lead package structure
• Compact physical dimensions suitable for space-constrained PCB layouts
• Fundamental frequency operation at 25 MHz with specified load capacitance

Applications

• General-purpose digital circuit clock generation
• Microcontroller system timing references
• Communication interface synchronization modules

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure correct load capacitance and stability ratings. Confirm that the four-terminal SMD no-lead package matches the target PCB footprint requirements. Cross-reference the part number with authorized distributors to validate authenticity and current availability status before finalizing procurement plans.

Selection Notes

Select this component when a 25 MHz reference signal with ±30 ppm stability is required for surface-mount designs. Ensure the circuit design accommodates an 8 pF load capacitance to maintain accurate frequency performance. Evaluate the mechanical constraints of the 3.2x2.5mm package to confirm compatibility with assembly processes and available board real estate.

Part Context

This part belongs to the QT325G series of quartz crystals, which are characterized by their small form factor and reliability. The series is widely utilized in consumer electronics and industrial equipment where standard-sized components cannot fit. The specific model denotes a 25 MHz variant within this family, sharing common packaging and electrical characteristics with other frequencies in the lineup.

Replacement Considerations

Direct substitutes include other 25 MHz crystals from different manufacturers offering identical 3.2x2.5mm footprints and 8pF load capacitance. Verify equivalent stability ratings and operating temperature ranges when considering alternative sources. Ensure that any replacement maintains the four-terminal SMD no-lead configuration for proper soldering and mechanical retention.
