Procurement Notes

Verify the specific suffix codes against official NDK documentation to ensure correct tolerance and packaging specifications. Confirm RoHS compliance status through current manufacturer declarations. Check for any recent series updates or pinout variations before finalizing procurement orders to avoid integration issues.

Selection Notes

Select this component when a 16 MHz reference with ±10 ppm initial tolerance is required. Ensure the target circuit design accommodates a 10 pF load capacitance and 80 Ohm ESR. Verify that the 3.2x2.5 mm footprint fits the available board space and that the operating temperature range meets the environmental requirements of the end application.

Part Context

This part belongs to NDK's standard SMD crystal lineup, utilizing their proprietary artificial crystal cultivation technology.
