QT325S-24.000MEIJ-T

Overview

The QT325S-24.000MEIJ-T is a quartz crystal resonator manufactured by QST, operating at a fundamental frequency of 24 MHz. It features a surface-mount design with dimensions of 3.2 x 2.5 x 0.7 mm and utilizes a four-terminal no-lead package configuration. The component exhibits a load capacitance of 18 pF and an equivalent series resistance of 50 Ohms. Frequency stability is specified at ±10 ppm at 25°C and ±20 ppm across the industrial temperature range of -40°C to +85°C.

Feature Summary

• Seam seal construction for enhanced environmental protection
• Four-terminal no-lead surface mount package design
• Industrial temperature range operation capability

Applications

• Microcontroller clock sources
• Communication module timing references
• Digital signal processing circuits

Procurement Notes

Verify the specific suffix MEIJ against official QST documentation to confirm the exact stability and packaging specifications. Ensure compatibility with reflow soldering profiles defined in the manufacturer's datasheet. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before procurement.

Selection Notes

Select this component when a 24 MHz reference with 18 pF load capacitance is required. The 50 Ohm ESR suits standard oscillator circuits. Consider the 3.2x2.5 mm footprint for space-constrained PCB layouts. Verify thermal requirements against the -40 to +85°C operational range.

Part Context

This part belongs to the QT325S series of seam seal crystals from QST. These components are designed for high reliability in compact electronic devices. The series offers various frequency options and stability grades within the same physical footprint, allowing for flexible design integration.

Replacement Considerations

Direct substitutes include other 24 MHz crystals with identical 3.2x2.5 mm dimensions, 18 pF load capacitance, and comparable ESR values. Verify that alternative parts meet the same ±10 ppm stability requirement at 25°C.
