CAT10-220J4LF is a chip resistor array containing four isolated resistors in an 0804 surface-mount package, each with a resistance value of 220 ohms and ±5% tolerance. The device features a thick-film resistive element on a high-purity alumina substrate with protective glass overcoat and tin-plated (RoHS-compliant) side terminations. It operates over a temperature range of -55°C to +125°C with a maximum working voltage of 25 V, a power rating of 0.0625 W per resistor, and a temperature coefficient of resistance of ±250 ppm/°C. The array is suitable for most soldering processes and is supplied on paper tape on plastic reel in quantities of 10,000 pieces per reel, making it ideal for automated assembly in applications requiring multiple isolated resistor networks.
