CAY16-4991F4LF is a four-element isolated resistor array featuring convex terminations and ±1% resistance tolerance, designed for precision applications requiring multiple independent resistive elements. The device offers a resistance range from 10 ohms to 1 megohm with a temperature coefficient of ±200 PPM/°C and operates reliably across -55°C to 125°C. With a maximum working voltage of 50 V, power rating of 0.0625 W per resistor (0.250 W package total at 70°C), and tin-plated RoHS-compliant terminations, this array is well-suited for compact circuit designs in consumer electronics, instrumentation, and industrial control systems where space efficiency and resistance accuracy are critical.
