4420P-2-393

4420P-2-393 Description

The 4420P-2-393 from Bourns Inc. is a high-performance 19-resistor bussed array designed for precision surface-mount applications. With a 39kΩ resistance per element and a tight ±2% tolerance, this component ensures reliable signal conditioning and voltage division in compact circuits. Its ±100ppm/°C temperature coefficient and 50ppm/°C resistor-ratio drift enhance stability across operating temperatures, making it suitable for environments with thermal fluctuations. The device is housed in a 20-pin SOIC package with dimensions of 12.95mm x 7.50mm (0.510" x 0.295") and a low-profile 2.90mm (0.114") seated height, ideal for space-constrained designs.

4420P-2-393 Features

• 19-resistor bussed network with 160mW power rating per element for robust performance.
• 39kΩ resistance and ±2% tolerance ensure precision in analog and digital circuits.
