The CAT16-000J4LF is a 4-element zero-ohm jumper chip resistor array with concave terminations designed for high-density PCB routing and signal bridging applications. Each element provides less than 0.05 ohm resistance with ±5% tolerance, rated at 0.0625 W per resistor and 0.250 W package power at 70 °C. The device operates across a temperature range of -55 °C to 125 °C with a temperature coefficient of ±200 PPM/°C, maximum working voltage of 50 V, and maximum overload voltage of 100 V. The array features tin-plated (RoHS compliant) terminations in a 1206 package size and is commonly used for PCB jumper connections, circuit modifications, and signal routing in consumer electronics, industrial control systems, and telecommunications equipment.
