Category
The C7570508 is a cost-effective 20MHz SMD crystal optimized for consumer electronics and communication systems. Its ±20ppm tolerance and 12pF load capacitance meet basic timing requirements with reliable performance in -20℃ to +70℃ environments. Soldering must avoid thermal damage while thermal management requires proper copper plane integration. Alternative models offer similar parameters but with trade-offs in tolerance or package dimensions.
