STDCRG2-10M

Overview

The STDCRG2-10M is a surface-mount MHz crystal manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a nominal frequency of 10 MHz with a frequency tolerance of ±20ppm and stability of ±30ppm. The component features an 8pF load capacitance and an equivalent series resistance (ESR) of 200 Ohms. Designed for fundamental mode operation, it utilizes a 4-SMD, No Lead package measuring 3.20mm x 2.50mm x 0.90mm maximum height. It supports a commercial operating temperature range of -10°C to 70°C and complies with RoHS specifications.

Feature Summary

• Fundamental resonance mode operation for stable frequency generation
• Compact 4-SMD no-lead surface mount package design
• Compliance with RoHS environmental standards

Applications

• General purpose clock signal generation in electronic circuits
• Timing reference sources for microcontroller systems
• Communication interface synchronization modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tolerance variants. Confirm that the required operating temperature range of -10°C to 70°C aligns with the application environment. Cross-reference the 200 Ohm ESR value with the oscillator circuit design requirements to ensure proper startup characteristics.

Selection Notes

Select this component when a 10 MHz fundamental mode crystal with ±20ppm tolerance is required. The 8pF load capacitance must match the oscillator circuit design. Consider the 200 Ohm ESR limit for circuit compatibility. Ensure the -10°C to 70°C temperature range meets operational needs. The 4-SMD package suits space-constrained surface mount assemblies.

Part Context

This part belongs to the NX3225GA series of surface-mount crystals from NDK. It shares the standard 3.2x2.5mm footprint common to this family. The STDCRG2 designation indicates specific performance characteristics within the series, distinguishing it from other variants like STDCRS2 or STDCQS1 which may offer different temperature ranges or automotive qualifications.

Replacement Considerations

Public confirmed substitute part numbers include CX3225GB10000D0HEQZ1 from KYOCERA AVX and ABM8N-10.0000MHZ-8-D2Y-T3 from Abracon LLC. Verify electrical parameters such as ESR and load capacitance before substitution.
