STDCRG2-30M

Overview

The STDCRG2-30M is a surface-mount quartz crystal manufactured by NDK. It operates at a fundamental frequency of 30 MHz with a load capacitance of 8 pF. The component exhibits a frequency tolerance of ±20 ppm and stability of ±30 ppm. Equivalent series resistance is specified at 50 Ohms. It utilizes a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a maximum height of 0.90 mm. The device supports base harmonic operation within a temperature range of -10°C to 70°C.

Feature Summary

• Compact 4-SMD surface-mount design for automated assembly
• Fundamental mode resonance for precise timing control
• RoHS compliant construction for environmental safety

Applications

• Microcontroller clock generation circuits
• Communication interface timing references
• Embedded system oscillator modules

Procurement Notes

Verify the specific suffix codes against the official NDK datasheet to ensure exact electrical parameters match the design requirements. Confirm that the ordering suffix corresponds to the intended packaging format, as variations exist between tape-and-reel and cut-strip options. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when a 30 MHz fundamental frequency with 8 pF load capacitance is required for space-constrained designs. Ensure the operating environment remains within the -10°C to 70°C range. Verify that the circuit impedance matches the 50 Ohm ESR specification. Consider the 4-SMD footprint dimensions for PCB layout compatibility and thermal management requirements during the initial design phase.

Part Context

This part belongs to the STD-CRG-2 series from NDK, designed for general-purpose timing applications. It shares the NX3225GA form factor with other variants in the family. The series provides standardized surface-mount solutions for consumer electronics and industrial equipment requiring reliable frequency reference sources without the need for additional housing or mounting hardware.
