4309R-101-333

4309R-101-333 Description

The 4309R-101-333 from Bourns Inc. is an 8-resistor bussed network array housed in a compact 9-pin SIP (Single In-line Package). Designed for through-hole mounting, it offers a resistance value of 33kΩ per element with a tight tolerance of ±2%, ensuring consistent performance in precision circuits. The device operates within a ±100ppm/°C temperature coefficient range, with a low resistor-ratio drift of 50ppm/°C, making it stable across varying thermal conditions. Its 200mW power rating per element and REACH compliance further enhance its reliability for industrial and commercial applications. Packaged in a tube, the array measures 0.884" x 0.085" (22.45mm x 2.16mm) with a seated height of 0.195" (4.95mm), optimizing space efficiency on PCBs.
