Category
The 7.3728MHz SMD crystal with ±10ppm tolerance and 20pF load capacitance is optimized for consumer electronics timing systems. Its ±30ppm stability over -40°C to +85°C makes it suitable for IoT devices and communication modules. Designers should implement proper thermal management with 0.3mm copper ground planes and avoid static discharge during assembly. While offering high precision at 0.2445$ per unit in 1-piece quantities, extended industrial applications require additional validation beyond commercial temperature ranges.
