Crystals Procurement Notes

Verify the specific suffix 'IAR' against the manufacturer's current datasheet to confirm packaging and material specifications. Cross-reference the part number with official CTS documentation to ensure compatibility with design-in requirements. Confirm that the 10 pF load capacitance matches the target circuit's oscillator configuration before procurement.

Crystals Selection Notes

Select this component when a 16 MHz fundamental frequency with ±10 ppm tolerance is required. Ensure the application circuit supports a 10 pF load capacitance to maintain specified frequency accuracy. Verify that the 120 Ohm ESR aligns with the oscillator driver strength capabilities of the host device.

Crystals Part Context

This part belongs to the CTS 402 Series of general-purpose crystals. The series offers various frequencies and packages optimized for consumer and industrial electronics.
