QT216S-48.000METE-T

Overview

The QT216S-48.000METE-T is a quartz crystal oscillator manufactured by QST, designed for surface-mount applications. It operates at a nominal frequency of 48 MHz with a ±10 ppm frequency stability at 25°C and across the -30°C to +85°C temperature range. The component features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 50 Ohms. It utilizes a seam seal package construction in a compact 4-SMD, No Lead footprint measuring 2.0 x 1.6 mm.

Feature Summary

• Seam seal construction for enhanced environmental protection
• High frequency stability within specified industrial temperature ranges
• Compact surface-mount design suitable for space-constrained PCB layouts

Applications

• Clock generation for microcontrollers and digital signal processors
• Timing references for communication interfaces such as UART and SPI
• Frequency control in consumer electronic devices requiring precise timing

Procurement Notes

Verify the specific suffix METE-T against official QST documentation to confirm the exact load capacitance and stability specifications. Ensure compatibility with the target circuit's oscillation requirements before procurement. Cross-reference the datasheet for handling instructions related to the seam seal package type.

Selection Notes

Select this component when a 48 MHz reference with tight ±10 ppm stability is required over an extended temperature range. The 12 pF load capacitance must match the oscillator circuit design. Consider the 50 Ohm ESR limit to ensure reliable startup conditions in the host application.

Part Context

This part belongs to the QT216S series of quartz crystals from QST, characterized by small 2.0x1.6 mm dimensions. The series offers various frequency options and stability grades, with the METE-T variant specifically optimized for high precision applications requiring stable performance under thermal variation.

Replacement Considerations

Direct substitutes include other 48 MHz crystals with identical 12 pF load capacitance and ±10 ppm stability. Verify that alternative components support the same 4-SMD no-lead package and seam seal technology to maintain mechanical and electrical equivalence.
