4311R-101-472

4311R-101-472 Description

The 4311R-101-472 from Bourns Inc. is a high-performance 10-resistor bussed network housed in an 11-pin SIP package, designed for precision through-hole applications. With a 4.7kΩ resistance per element and a tight ±2% tolerance, this device ensures reliable signal conditioning and voltage division in demanding circuits. Its ±100ppm/°C temperature coefficient and 50ppm/°C resistor-ratio drift enhance stability across operating temperatures, making it ideal for environments with thermal fluctuations. The compact 1.084" x 0.085" (27.53mm x 2.16mm) footprint and 0.195" (4.95mm) seated height allow efficient PCB space utilization. Packaged in tubes, it supports streamlined assembly processes.
