STDCRA2-16M

Overview

The STDCRA2-16M is a surface-mount crystal resonator manufactured by NDK. It operates at a fundamental frequency of 16 MHz with a load capacitance of 8 pF. The component exhibits a frequency tolerance of ±50 ppm and an equivalent series resistance (ESR) of 120 Ohms. It utilizes a 2-SMD, no-lead package configuration, measuring approximately 2.0 mm in length and 1.2 mm in width. The device is designed for base mode operation and supports a standard operating temperature range.

Feature Summary

• Compact 2-SMD footprint suitable for space-constrained designs
• Fundamental oscillation mode for stable clock generation
• RoHS compliant construction

Applications

• General-purpose microcontroller clock sources
• Consumer electronic timing circuits
• Industrial control system oscillators

Procurement Notes

Verify the specific package variant against the manufacturer's current datasheet to ensure compatibility with automated pick-and-place equipment. Confirm that the 120 Ohm ESR aligns with the oscillator circuit design requirements. Check for any recent updates to the RoHS compliance documentation or material declarations prior to finalizing procurement orders.

Selection Notes

Select this component when a small form factor is required alongside moderate frequency stability. The 16 MHz frequency is common for basic timing applications. Ensure the circuit can drive the 120 Ohm ESR without excessive loading. Compare against higher stability options if tighter tolerance is needed for the specific application environment.

Part Context

This part belongs to NDK's SMD crystal lineup, which emphasizes miniaturization and reliability. NDK manufactures these components using proprietary quartz cultivation technologies. The STDCRA2 series represents a compact solution within their broader portfolio of frequency control devices used in various electronic markets.

Replacement Considerations

Direct substitutes must match the 16 MHz frequency, 8 pF load capacitance, and 2-SMD package dimensions. Verify ESR compatibility to prevent start-up failures. Cross-reference with other manufacturers offering similar miniature crystals if supply constraints exist.
