QT325S-48.000MAAV-T

Overview

The QST QT325S-48.000MAAV-T is a quartz crystal resonator operating at a fundamental frequency of 48 MHz. It features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 50 Ohms. The component exhibits a frequency stability of ±30 ppm at 25°C and maintains ±30 ppm across the temperature range of -20°C to +70°C. It utilizes a 4-SMD, No Lead package with dimensions of 3.2 x 2.5 mm.

Feature Summary

• Provides stable oscillation at 48 MHz with ±30 ppm frequency tolerance
• Designed for surface-mount integration via leadless SMD footprint
• Operates reliably within standard commercial temperature ranges

Applications

• Microcontroller clock sources
• Communication module timing circuits
• Embedded system oscillator references

Procurement Notes

Verify the specific suffix AAV against official QST documentation to confirm the 12 pF load capacitance specification. Ensure the required frequency stability meets the ±30 ppm requirement for your application environment. Confirm RoHS compliance status through manufacturer datasheets prior to procurement.

Selection Notes

Select this component when a 48 MHz reference is required with moderate stability. The 12 pF load capacitance must match the oscillator circuit design. Consider the -20°C to +70°C operating range suitability for the target deployment environment.

Part Context

This part belongs to the QT325S series of thin-film or bulk acoustic wave crystals from QST. These components are designed for compact electronic designs requiring precise frequency control in space-constrained applications.

Replacement Considerations

Cross-reference with other manufacturers offering 48 MHz crystals in 3.2x2.5mm packages. Verify identical load capacitance (12pF) and ESR (50 Ohm) specifications before substitution.
