STDCRG2-16M

Overview

The STDCRG2-16M is a surface-mount crystal resonator manufactured by NDK, belonging to the NX3225GA series. It operates at a fundamental frequency of 16 MHz with a load capacitance of 8 pF. The component features a frequency tolerance of ±20 ppm and stability of ±30 ppm. It has an equivalent series resistance (ESR) of 80 Ohms and supports base harmonic operation. Designed for -40°C to +85°C environments, it utilizes a 4-SMD, no-lead package measuring 3.20mm x 2.50mm x 0.90mm maximum height.

Feature Summary

• Compliant with RoHS specifications and classified under EAR99 export control.
• Engineered for surface mount installation in compact electronic assemblies.
• Operates in fundamental mode suitable for standard clocking applications.

Applications

• General-purpose digital circuit timing
• Microcontroller clock sources
• Consumer electronics signal generation

Procurement Notes

Verify that the specific order matches the NX3225GA series designation and 16 MHz frequency requirement. Confirm package dimensions align with PCB footprint constraints. Ensure environmental ratings meet operational temperature needs. Check for updated product change notifications regarding manufacturing origin or material composition before finalizing procurement plans.

Selection Notes

Select this component when a 16 MHz fundamental frequency is required within a 3.2x2.5 mm SMD form factor. Consider the 80 Ohm ESR value for oscillator circuit design compatibility. Evaluate the ±20 ppm tolerance against system clock accuracy requirements. Verify that the 8 pF load capacitance matches the host circuit's design parameters.
