Crystals Procurement Notes

Verify the specific suffix 'XIAR' against official CTS documentation to confirm packaging and tape specifications. Ensure compatibility with existing circuit load capacitance requirements. Confirm RoHS compliance status through current manufacturer declarations. Validate that the fundamental mode operation aligns with the target oscillator design parameters before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 54 MHz fundamental frequency is required in a compact SMD form factor. The 10 pF load capacitance must match the oscillator circuit's total capacitive load. Consider the 60 Ohm ESR value for drive level sensitivity. This part is suitable for applications requiring ±10 ppm initial tolerance within the specified industrial temperature range.

Crystals Part Context

This model belongs to the CTS 402 Series, which provides sub-miniature surface mount crystals. The series covers frequencies from 16 MHz to 96 MHz in a standardized 2.0 x 1.6 mm package. The 402F5401XIAR specifically addresses the need for precise timing in space-constrained modern electronics.
