Crystals Procurement Notes

Verify the specific ordering suffix 'CKT' to confirm the tape and reel packaging configuration. Ensure the selected variant matches the required 8pF load capacitance and 60 Ohm ESR specifications for the target circuit design. Cross-reference the manufacturer part number against official CTS documentation to validate authenticity and current production status before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency with 8pF load capacitance is required. The 4-SMD footprint suits applications with limited board space constraints. Verify that the ±30 ppm tolerance meets the system's timing accuracy requirements and that the -20°C to +70°C temperature range aligns with the operational environment.

Crystals Part Context

This component belongs to the CTS 402 Series of surface-mount crystals. The series offers various frequencies and package sizes designed for general-purpose timing applications. The 402F40033CKT specifically addresses the need for a 40 MHz reference in compact SMD form factors, providing a balance between performance and physical size for modern electronics.

Crystals Replacement Considerations

Direct substitutes include the 402F40033CAR and 402F40033CJR variants from CTS-Frequency Controls. These alternatives share identical electrical parameters but may differ in packaging or minor mechanical attributes. Verify pin compatibility and load capacitance matching before implementing any cross-brand replacements.
