Crystals Procurement Notes

Verify the exact physical dimensions and pin configuration against the official datasheet before integration, as visual representations may not reflect precise manufacturing tolerances. Confirm that the 4-SMD No Lead package aligns with your PCB footprint requirements. Ensure the 12pF load capacitance matches your circuit design specifications to maintain the stated ±10ppm accuracy. Contact the manufacturer or authorized distributors directly for current availability and lead times, as order volumes can impact delivery schedules.

Crystals Selection Notes

Select this component when a 48 MHz reference signal is required in a minimal footprint environment. The 50 Ohm ESR value should be compatible with your oscillator circuit's drive level constraints. Consider the KX-2 series characteristics if miniaturization is a primary design driver. Verify that the ±10ppm tolerance meets the system's frequency stability requirements over the intended operating temperature range. Ensure the passive nature of the crystal fits within the overall bill of materials strategy.
