Crystals Procurement Notes

Verify the specific suffix IJR against the manufacturer's official datasheet to confirm pin configuration and tape/reel specifications. Ensure the required load capacitance matches the target circuit design before procurement. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the ESR value with oscillator driver strength requirements to prevent over-driving or failure to start.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required with ±20 ppm stability. The 9 pF load capacitance must align with the host oscillator circuit's capacitive load. Consider the 60 Ohm ESR for drive level sensitivity. The 4-SMD package size suits space-constrained designs requiring surface mount technology compatibility.
