Category
The Seiko Epson Q13FC13500002 is a 32.768kHz surface mount crystal optimized for precision timing in industrial and consumer electronics. Its ±20ppm tolerance and -40°C to +85°C operating range make it suitable for RTCs, BMS, and IoT devices. Critical design considerations include minimizing trace lengths, ensuring proper thermal management, and verifying voltage compatibility. While it offers superior accuracy and environmental robustness, its cost and limited frequency specialization may not suit applications requiring multi-frequency support or ultra-low cost solutions.
