4420P-2-473

4420P-2-473 Description

The 4420P-2-473 from Bourns Inc. is a high-performance 19-resistor bussed network in a compact 20-pin SOIC package, designed for precision surface-mount applications. It features a 47kΩ resistance per element with a tight ±2% tolerance, ensuring reliable signal conditioning and voltage division. The device operates within a ±100ppm/°C temperature coefficient and offers a 50ppm/°C resistor-ratio drift, making it stable across varying thermal conditions. With a 160mW power rating per element and a low-profile 0.114" (2.90mm) height, it suits space-constrained designs. Compliant with REACH and MSL 1 (Unlimited), it is ideal for automated assembly.
