Crystals Procurement Notes

Verify the specific suffix 'IJT' against official CTS datasheets to confirm tape-and-reel packaging and exact parameter alignment. Ensure compatibility with existing PCB footprints measuring 2.00mm by 1.60mm. Confirm that the 9pF load capacitance matches the oscillator circuit design requirements before integration.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required with tight ±10ppm tolerance. The 402 series provides a balance of size and performance. Verify that the 60 Ohm ESR is compatible with the host oscillator's drive level specifications to prevent over-driving or failure to start.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series is characterized by small form factors and reliable performance for general-purpose timing applications. The 402F37412IJT specifically utilizes the standard 4-SMD footprint common in modern consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes include other 402 series variants with matching 37.4 MHz frequency and 9pF load capacitance. Cross-reference with 402F37412IJR for reel vs. tray packaging differences if applicable. Ensure any replacement maintains the same ±10ppm tolerance and 60 Ohm ESR specifications.
