STDCRG1-20M

Overview

STDCRG1-20M is a surface-mount MHz crystal manufactured by NDK, belonging to the NX3225GA series. It operates at a fundamental frequency of 20 MHz with a load capacitance of 8 pF. The component features a frequency tolerance of ±20 ppm and a frequency stability of ±30 ppm. It utilizes a 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm and a maximum height of 0.90mm. The equivalent series resistance is specified at 50 Ohms. The device supports base harmonic operation and is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Compact 4-SMD surface-mount design suitable for space-constrained applications
• High frequency stability within industrial temperature ranges
• Compliant with RoHS3 environmental standards

Applications

• Industrial control systems requiring stable clock signals
• Consumer electronics utilizing 20 MHz reference frequencies
• Automotive infotainment and communication modules

Procurement Notes

Verify the specific suffix configuration against the official NDK datasheet to ensure compatibility with target circuit parameters. Confirm that the 8 pF load capacitance matches the oscillator circuit requirements. Check for updated REACH compliance documentation prior to final procurement decisions.

Selection Notes

Select this component when a 20 MHz fundamental mode crystal is required in a 3.2x2.5 mm footprint. Ensure the system oscillator can support the specified 50 Ohm ESR. Consider the -40°C to 85°C temperature range against application demands. Verify that the ±20 ppm tolerance meets the timing accuracy requirements of the host microcontroller or processor.

Part Context

The STDCRG1-20M belongs to the NX3225GA series of SMD crystals from NDK. This series is designed for general-purpose applications requiring reliable frequency generation. The part shares the physical footprint with other variants in the NX3225GA family but differs in electrical specifications such as frequency and tolerance.

Replacement Considerations

STDCRG2-20M is a documented substitute with identical 20 MHz frequency and 8 pF load capacitance. Verify if the slight differences in height or ESR between the RG1 and RG2 suffixes impact the specific PCB layout or oscillator circuit design.
