CAY16-220J4LF is a 4-element chip resistor array featuring convex terminations and tin-plated (RoHS compliant) leads. Each resistor element is rated at 220 ohms with ±5% tolerance, offering a resistance range from 10 ohms to 1 megohm across the series. The device is rated for 0.0625 W per resistor at 70°C with a maximum working voltage of 50 V and operates reliably across a temperature range of -55°C to 125°C, with a temperature coefficient of ±200 PPM/°C. The array is housed in a 1206 package size and is designed for high-reliability applications requiring multiple isolated resistor elements in a compact form factor. Common applications include signal conditioning, impedance matching, and circuit biasing in consumer electronics, industrial equipment, and telecommunications systems.
