QT325G-16.000MEIJ-T

Overview

The QT325G-16.000MEIJ-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications with dimensions of 3.2mm x 2.5mm x 0.8mm. It operates at a fundamental frequency of 16 MHz and utilizes a load capacitance of 18 pF. The component exhibits an equivalent series resistance of 60 Ohms maximum. Frequency stability is specified at ±10 ppm over the temperature range of -20°C to +70°C. This device is housed in a four-terminal SMD package without leads, ensuring reliable integration into compact electronic circuits requiring precise timing signals.

Feature Summary

• Surface-mount design with no lead construction for automated assembly
• High frequency stability of ±10 ppm within standard operating temperatures
• Compact 3.2x2.5mm footprint suitable for space-constrained PCB layouts

Applications

• Mobile communication devices
• Consumer electronics timing circuits
• Embedded system clock sources

Procurement Notes

Verify the specific suffix MEIJ-T against official QST documentation to confirm the ±10 ppm stability rating and 18 pF load capacitance. Ensure compatibility with reflow soldering profiles specified in the datasheet. Confirm that the 4-SMD no-lead package matches the target board footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a 16 MHz reference signal with tight tolerance is required for mobile or consumer applications. The ±10 ppm stability offers superior performance compared to standard ±30 ppm variants. Consider the 18 pF load capacitance requirement for oscillator circuit design to ensure accurate frequency generation without additional tuning adjustments.

Part Context

This part belongs to the QST QT325G series of thin film bulk acoustic resonator (FBAR) or similar advanced quartz crystals. The series provides various stability options denoted by suffix letters, with 'E' indicating ±10 ppm performance. The model integrates high-frequency precision into a small form factor, addressing industry trends toward miniaturization in portable electronics.

Replacement Considerations

Compatible substitutes include other QT325G variants with matching 16 MHz frequency and 18 pF load capacitance. Verify that alternative parts maintain the same ±10 ppm stability rating and 4-SMD no-lead package dimensions to ensure mechanical and electrical interchangeability.
