CAT10-101J4LF is a chip resistor array containing four isolated resistors in an 0804 surface-mount package, designed for high-density circuit integration. The device features E24 series resistance values ranging from 10 ohms to 1 megohm with ±5% tolerance, a maximum working voltage of 25 V, and a temperature coefficient of resistance (TCR) of ±250 ppm/°C. Each resistor is rated for 0.0625 W at 70°C, with a total package power rating of 0.250 W, and operates reliably across the temperature range of -55°C to +125°C. The array utilizes thick-film construction on a high-purity alumina substrate with protective glass overcoat and tin-plated (RoHS-compliant) terminations, making it suitable for automated assembly and most soldering processes. This component is ideal for applications requiring multiple isolated resistors in compact form factors, such as signal conditioning, impedance matching, and biasing networks in consumer electronics, industrial controls, and telecommunications equipment.
