Category
The C7570539 20MHz SMD crystal provides a cost-effective solution for timing applications requiring ±20ppm accuracy within -40°C to +85°C. Its 12pF load capacitance suits standard oscillator circuits, with design considerations emphasizing short trace routing and thermal management. The RoHS-compliant Surface Mount package supports high-volume production but lacks extended temperature grades for harsh environments.
