QT325S-20.000MEIE-T

Overview

The QT325S-20.000MEIE-T is a quartz crystal resonator manufactured by QST Products, LLC. It operates at a fundamental frequency of 20 MHz with a frequency tolerance of ±10 ppm and a load capacitance of 12 pF. The component features an equivalent series resistance (ESR) of 80 Ohms maximum. It utilizes the SMD3225-4P package, measuring 3.2 mm in length, 2.5 mm in width, and 0.7 mm in height. Designed for surface-mount assembly, it supports base harmonic operation mode.

Feature Summary

Provides stable timing signals for embedded communication applications
Offers reliable integration with existing software tools
Supports efficient setup for microcontroller-based projects

Applications

Embedded communication systems requiring precise clock synchronization
Microcontroller unit (MCU) clock sources
Human-machine interface (HMI) display projects

Procurement Notes

Verify the specific ordering suffix to ensure the correct load capacitance and tolerance specifications match the design requirements. Confirm that the SMD3225-4P package dimensions align with the PCB footprint. Check the manufacturer's latest documentation for any product change notices or environmental compliance updates prior to finalizing procurement plans.

Selection Notes

Select this component when a 20 MHz fundamental frequency with ±10 ppm stability is required. Ensure the circuit design accommodates the 12 pF load capacitance and 80 Ohm ESR limits. Consider the physical size constraints of the 3.2x2.5mm package during layout planning. Validate compatibility with the target microcontroller's oscillator input specifications.
