QT325S-48.000MEIV-T

Overview

The QT325S-48.000MEIV-T is a quartz crystal resonator from the QT325S series manufactured by QST. It operates at a fundamental frequency of 48 MHz with a load capacitance of 8 pF. The component exhibits a frequency stability of ±10 ppm at +25°C and ±20 ppm over the operating temperature range of -40°C to +85°C. It utilizes a surface-mount package measuring 3.2 x 2.5 x 0.7 mm, designed for compact electronic circuit integration.

Feature Summary

• Provides precise timing signals via quartz resonance technology
• Ensures stable frequency output across industrial temperature ranges
• Supports space-constrained designs through small surface-mount packaging

Applications

• Microcontroller clock sources
• Communication interface timing
• Digital signal processing circuits

Procurement Notes

Verify the specific suffix MEIV-T against official QST documentation to confirm the exact electrical parameters, particularly the 8 pF load capacitance and ±10 ppm initial tolerance. Ensure the requested part matches the physical dimensions and mounting style required for the target PCB layout. Cross-reference manufacturer datasheets to validate availability and compliance standards before finalizing procurement orders.

Selection Notes

Select this component when a 48 MHz reference is required with high initial accuracy of ±10 ppm. The 8 pF load capacitance specification must align with the oscillator circuit design. Consider the -40°C to +85°C temperature range for environmental suitability. The small form factor makes it suitable for dense board layouts where larger crystals cannot fit.

Part Context

This part belongs to the QT325S series of surface-mount quartz crystals. The series offers various frequencies and stability options within a standardized 3.2 x 2.5 mm footprint. This specific model targets applications requiring moderate stability and low profile, distinguishing it from higher-stability or larger-package variants in the same product family.

Replacement Considerations

Direct substitutes include other 48 MHz crystals with identical 8 pF load capacitance and ±10 ppm stability. Verify that alternative parts match the 3.2 x 2.5 x 0.7 mm package dimensions. Check if competitor components offer equivalent temperature stability ranges and soldering compatibility for seamless integration.
