Crystals Procurement Notes

Verify the specific ordering suffix and tape/reel specifications against the official manufacturer datasheet prior to procurement. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint. Ensure the selected variant meets the required ±30 ppm tolerance and 60 Ohm ESR parameters for the intended circuit design. Cross-reference the active status and longevity data directly from Suntsu Electronics documentation to avoid obsolescence risks.

Crystals Selection Notes

Select this component when a precise 40 MHz reference signal is required for digital logic or communication interfaces. The 12 pF load capacitance must match the oscillator circuit requirements specified in the host microcontroller or FPGA datasheet. Consider the 60 Ohm ESR value to ensure proper oscillation startup conditions. The wide temperature range makes it suitable for harsh environments where standard commercial grade parts may fail.
