Crystals Procurement Notes

Verify the specific frequency tolerance and ESR requirements against your circuit design before ordering. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Ensure the operating temperature range meets the environmental conditions of your final application. Cross-reference the manufacturer's datasheet for soldering profile recommendations to prevent component damage during assembly.

Crystals Selection Notes

Select this component when a 27.12 MHz reference is required for low-cost, space-constrained designs. The 7 pF load capacitance must match the external capacitors in the oscillator circuit to maintain accuracy. Consider the ±30 ppm tolerance if higher precision is not critical. The 150 Ohm ESR value should be compatible with the driving strength of the host oscillator IC. Evaluate thermal stability needs against the specified -30°C to +85°C range.
