Crystals Procurement Notes

Verify the specific suffix 'IKT' corresponds to tape-and-reel packaging requirements. Confirm that the 8pF load capacitance matches the target circuit design. Check current availability status as distribution channels may indicate discontinuation or limited stock. Ensure compatibility with standard reflow soldering profiles for 4-SMD packages.

Crystals Selection Notes

Select this component when a 20MHz fundamental crystal is required in a small 2.0x1.6mm package. The 8pF load capacitance must align with the oscillator circuit's stray capacitance. Consider the 100 Ohm ESR for oscillator startup reliability. Verify that the ±10ppm initial tolerance meets system accuracy requirements.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. It shares dimensional characteristics with other variants in the series but differs in frequency and load capacitance. The 402 series provides options for various frequencies within the same compact form factor, facilitating board space optimization across different product designs.
