Category
The C7570515 32.768kHz surface mount crystal provides stable timing solutions for low-frequency applications with ±20ppm tolerance and 6pF load capacitance in a compact MC-146 package. Ideal for real-time clocks and battery-operated devices, it requires careful soldering techniques and operates within -40°C to +85°C. Alternative models offer similar frequencies but with different tolerance ranges, while design considerations emphasize thermal management and layout stability. Marketed as a cost-effective timing solution with RoHS compliance, it serves medical devices and IoT applications but lacks extended temperature variants and has a minimum order requirement.
