4420P-2-820

4420P-2-820 Description

The 4420P-2-820 from Bourns Inc. is a high-performance 19-resistor bussed array designed for precision surface-mount applications. With a resistance value of 82Ω 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 varying thermal conditions. Encased in a 20-pin SOIC package with dimensions of 12.95mm x 7.50mm (0.510" x 0.295"), it offers a low-profile seated height of 2.90mm (0.114"), making it suitable for space-constrained designs. The 160mW power rating per element and MSL 1 (Unlimited) moisture sensitivity further underscore its robustness for industrial and commercial use.
