QT325S-48.000MEEE-T

Overview

The QT325S-48.000MEEE-T is a quartz crystal resonator manufactured by QST, operating at a fundamental frequency of 48.000 MHz. It utilizes a 4-SMD, No Lead package with dimensions of 3.2mm x 2.5mm x 0.7mm. The component features a load capacitance of 12pF and an equivalent series resistance (ESR) of 50 Ohms. Frequency stability is specified at ±10ppm over the temperature range of -20°C to +70°C.

Feature Summary

• Seam seal construction for enhanced environmental protection
• Low profile surface mount design suitable for automated assembly
• High frequency stability within specified industrial temperature ranges

Applications

• Microcontroller clock sources
• Communication module timing references
• Consumer electronics internal clocks

Procurement Notes

Verify the specific suffix 'E' confirms the ±10ppm stability rating at -20°C to +70°C against official QST documentation. Ensure the ordering part number matches the exact electrical parameters required for the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when a 48MHz reference signal is required in a compact SMD footprint. The 12pF load capacitance must match the oscillator circuit requirements. Verify that the ±10ppm stability meets the system timing tolerance specifications.

Part Context

This part belongs to the QT325S family of seam seal crystals from QST. These devices are designed for high-volume surface mount applications requiring reliable timing performance in consumer and industrial electronic products.

Replacement Considerations

Compatible substitutes include other 48MHz crystals with identical 3.2x2.5mm dimensions, 12pF load capacitance, and ±10ppm stability ratings. Verify pin compatibility and mounting pad layout alignment before substitution.
