CAT16-510J4LF is a four-element isolated chip resistor array featuring concave terminations and RoHS-compliant tin-plated (LF) leads. The device contains four isolated resistors with a nominal resistance value of 51 ohms (decoded from "510" in the part number), ±5% tolerance, and is housed in a 1206 package size. It delivers 0.0625 W per resistor at 70°C with a maximum working voltage of 50 V and operates reliably across the temperature range of -55°C to 125°C, with a temperature coefficient of ±200 PPM/°C. The array is ideal for applications requiring multiple isolated resistor functions in compact form factors, such as signal conditioning, impedance matching, and circuit protection in consumer electronics, industrial control systems, and telecommunications equipment.
