Crystals Procurement Notes

Verify the specific ordering suffix IVR to ensure correct packaging quantity and reel specifications. Confirm that the load capacitance matches the target circuit design requirements. Check the manufacturer datasheet for detailed mechanical dimensions and soldering profile recommendations to ensure proper surface mount assembly. Ensure the operating temperature range aligns with the final product's environmental conditions.

Crystals Selection Notes

Select this component when a small form factor is critical for PCB space constraints. The 20MHz frequency is suitable for microcontroller clock sources or RF reference signals. Consider the ±10ppm tolerance if high precision is required for communication protocols. Evaluate the 7pF load capacitance against the oscillator circuit's internal capacitance to achieve accurate frequency output.

Crystals Part Context

This part belongs to the CTS IoT Enhanced Quartz Crystal series, which focuses on miniaturization and performance for connected devices. It competes with other surface mount crystals in the 3225 package style. The 403WF series is distinct from through-hole or larger SMD variants, offering a balance between size and electrical stability for modern compact electronics.

Crystals Replacement Considerations

Substitutes must match the 20MHz frequency, 3.2x2.5mm package, and 7pF load capacitance. Verify that alternative parts offer comparable stability and tolerance ratings. Ensure the replacement component supports the same operating temperature range and mounting type.
