4420P-2-472LF

4420P-2-472LF Description

The 4420P-2-472LF from Bourns Inc. is a high-performance 19-resistor bussed network designed for precision surface-mount applications. With a 4.7kΩ resistance per element and a tight ±2% tolerance, this device ensures reliable signal conditioning and voltage division in compact PCB designs. Housed in a 20-pin SOIC package (12.95mm x 7.50mm), it features a low-profile 2.90mm seated height, making it suitable for space-constrained environments. The ±100ppm/°C temperature coefficient and 50ppm/°C resistor-ratio drift enhance stability across operating temperatures, while the 160mW power rating per element supports robust performance in demanding circuits.
