Crystals Procurement Notes

Verify the specific suffix 'IDT' against official CTS documentation to confirm tape-and-reel packaging and exact electrical tolerances. Ensure compatibility with the target PCB footprint, specifically the 4-SMD no-lead outline. Cross-reference moisture sensitivity levels and reflow soldering profiles with manufacturing requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 40 MHz reference with ±20 ppm stability is required in a compact surface-mount form factor. The 18 pF load capacitance must match the oscillator circuit design specifications. Consider the 60 Ohm ESR value for impedance matching purposes. Verify that the operating temperature range meets the environmental constraints of the intended application environment.

Crystals Part Context

This part belongs to the 402 series of surface-mount crystals from CTS-Frequency Controls. The series offers various frequencies and package sizes optimized for consumer and industrial electronics. The 402F40022IDT specifically addresses the need for stable timing in space-constrained designs requiring fundamental mode resonance.

Crystals Replacement Considerations

Direct substitutes include the 402F40022IDR variant, which shares identical electrical characteristics but may differ in packaging configuration. Verify pinout compatibility and mechanical dimensions before swapping components to ensure proper board integration.
