The Bourns CAY16 series chip resistor arrays are designed for applications requiring multiple isolated resistors in a small footprint. These arrays offer resistance values ranging from 10 ohms to 1 megohm, with tolerance options of ±1% and ±5%. They are RoHS compliant and feature convex terminals for reliable soldering. The CAY16-221J4LF specifically provides a compact solution for power management, signal termination, and other circuit functions where precise resistance is critical. Their small size and multiple element design make them ideal for space-constrained applications in consumer electronics, industrial equipment, and automotive systems.
