CAT16-223J4LF is a 4-element chip resistor array featuring concave terminations and tin-plated (RoHS compliant) leads. The device contains 4 isolated resistors with a nominal resistance value of 22 kO (decoded from "223" = 22 × 10³ ohms) and ±5% tolerance. It operates over a temperature range of -55°C to 125°C with a temperature coefficient of ±200 PPM/°C, and supports a maximum working voltage of 50 V and maximum overload voltage of 100 V. The package provides a power rating of 0.250 W at 70°C (0.0625 W per individual resistor), making it suitable for compact circuit designs requiring multiple matched resistors in applications such as signal conditioning, impedance matching, and precision measurement circuits.
