Crystals Procurement Notes

Verify the specific suffix 'XIJT' against official CTS documentation to confirm packaging type and tape/reel specifications. Ensure compatibility with the target circuit's load capacitance requirements, as this component specifies 9pF. Check for moisture sensitivity level constraints during storage and handling prior to soldering. Confirm that the operating temperature range meets the environmental demands of the final application.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental frequency is required with tight ±10 ppm stability. The 9pF load capacitance must match the oscillator circuit design to ensure accurate frequency performance. Consider the 60 Ohm ESR value for drive level limitations. The small 2.00mm x 1.60mm footprint is suitable for space-constrained PCB layouts requiring surface mount technology.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series provides various frequencies and packages for general-purpose timing applications. The 402F3841XIJT specifically addresses the need for stable clock signals in digital electronics using a standard SMD form factor.

Crystals Replacement Considerations

Consult official CTS cross-reference guides for direct substitutes. Verify that any replacement matches the 38.4 MHz frequency, 9pF load capacitance, and 4-SMD package dimensions. Ensure equivalent electrical parameters such as ESR and stability are maintained.
