QT325S-32.000MEIV-T

Overview

The QT325S-32.000MEIV-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a fundamental frequency of 32.000 MHz and utilizes an SMD package with physical dimensions of 3.2 x 2.5 x 0.7 mm. The component features a load capacitance of 8 pF and offers a frequency tolerance of ±10 ppm at 25°C. Frequency stability is rated at ±20 ppm across the operating temperature range of -40°C to +85°C.

Feature Summary

• Surface-mount quartz crystal resonator optimized for compact electronic designs
• High frequency stability within specified industrial temperature ranges
• Standardized 8 pF load capacitance for circuit integration

Applications

• Microcontroller clock sources
• Communication module timing references
• Industrial control system oscillators

Procurement Notes

Verify that the specific suffix MEIV corresponds to the required 8 pF load capacitance and ±20 ppm stability profile. Ensure the procurement documentation confirms the -40°C to +85°C operating range matches the target application environment. Cross-reference the 3.2x2.5mm footprint against PCB design constraints to guarantee proper placement and soldering compatibility.

Selection Notes

Select this component when a 32 MHz reference signal is required in space-constrained designs. The 8 pF load capacitance suits circuits designed for this specific value, differing from common 12 pF or 18 pF alternatives. Consider the ±20 ppm stability rating against system timing requirements, as it provides moderate precision suitable for general-purpose digital logic rather than high-precision communication standards requiring tighter tolerances.

Part Context

This part belongs to the QT325S series of thin-type surface-mount crystals. The series offers various frequency options and stability grades, distinguished by alphanumeric suffixes indicating temperature ranges and tolerance levels. This specific model represents a mid-range stability option within the 32 MHz product line, balancing performance with standard packaging dimensions.

Replacement Considerations

Direct substitutes include other manufacturers' 32 MHz crystals in 3250 packages with 8 pF load capacitance. Verify equivalent stability ratings and operating temperature ranges before substitution. Ensure pinout and electrical characteristics match to avoid circuit redesign.
