QT325G-20.000MAHE-T

Overview

The QT325G-20.000MAHE-T is a quartz crystal resonator manufactured by QST Products, LLC. It operates at a fundamental frequency of 20 MHz with a load capacitance of 12 pF and an equivalent series resistance of 60 Ohms. The component features a frequency tolerance of ±30 ppm at 25°C and maintains stability within ±30 ppm across the operating temperature range of -40°C to +85°C. It utilizes a 4-SMD, No Lead package with dimensions of 3.2 mm x 2.5 mm and a maximum seated height of 0.90 mm.

Feature Summary

• Provides precise timing signals at 20 MHz with stable frequency characteristics across industrial temperature ranges.
• Utilizes a compact surface-mount package design suitable for automated assembly processes.
• Ensures reliable operation with specified electrical parameters including low equivalent series resistance.

Applications

• Microcontroller clock sources
• Communication module timing references
• Industrial control system oscillators

Procurement Notes

Verify the manufacturer designation as QST Products, LLC against official documentation. Confirm that the specific suffix HE-T aligns with the required load capacitance and temperature specifications. Ensure compatibility with the target PCB footprint and reflow soldering profiles before integration into production lines.

Selection Notes

Select this component when a 20 MHz reference is required with ±30 ppm stability in harsh environments. The 12 pF load capacitance must match the oscillator circuit design. Consider the 4-SMD no-lead form factor for space-constrained layouts requiring robust thermal performance.

Part Context

This part belongs to the QT325G series of quartz crystals designed for general-purpose timing applications. The series offers various frequency options within a standardized small outline package. The specific model denotes the 20 MHz variant with defined tolerance and temperature coefficients for electronic circuits.

Replacement Considerations

Direct substitutes include other 20 MHz crystals with identical 3.2x2.5 mm dimensions and 12 pF load capacitance. Verify that alternative parts meet the same ±30 ppm tolerance and -40°C to +85°C operating range requirements.
