Category
The 16MHz HC-49S-SMD crystal with ±20ppm tolerance is optimized for timing applications requiring high precision in consumer and industrial electronics. Its surface mount design ensures compact integration while maintaining stability across -20°C to +70°C. The RoHS-compliant component is cost-competitive for mass production but lacks extended temperature ranges or integrated features, making it suitable for general-purpose timing needs but requiring external compensation in extreme environments.
