CAT16-105J4LF 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 value of 1 megohm (105 code) and ±5% tolerance, offering a resistance range from 10 ohms to 1 megohm. 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, maintaining a temperature coefficient of ±200 PPM/°C. The 1206 package size and convex/concave terminal options make it suitable for space-constrained applications in consumer electronics, industrial control systems, and telecommunications equipment where multiple isolated resistor networks are required.
