Crystals Procurement Notes

Verify the specific suffix 'HKR' corresponds to the tape-and-reel packaging format containing 3,000 units per reel as documented. Confirm that the 8 pF load capacitance matches the target circuit design before integration. Ensure compliance with RoHS3 standards if environmental regulations apply to the final assembly. Cross-reference the 70 Ohm maximum ESR against the oscillator circuit specifications to guarantee reliable startup conditions.

Crystals Selection Notes

Select this component when a 16 MHz fundamental mode crystal is required for IoT or industrial environments. The wide temperature range makes it suitable for harsh conditions where standard commercial parts may fail. The 8 pF load capacitance must align with the host system's external capacitors. Consider the 4-SMD package size for board space optimization compared to larger through-hole alternatives.

Crystals Part Context

This component belongs to the CTS 403W series, which focuses on enhanced quartz crystals for modern embedded systems. The series addresses the need for reliability in connected devices. The 403WF16015HKR specifically targets the 16 MHz frequency point within the 3.2mm x 2.5mm form factor. It represents a shift toward smaller, more robust timing solutions for next-generation hardware.
