4309R-101-181 Description

The 4309R-101-181 from Bourns Inc. is a high-performance 8-resistor bussed network designed for precision applications in electronic circuits. With a resistance value of 180Ω per element and a tight ±2% tolerance, this device ensures reliable signal conditioning and voltage division. Housed in a 9-pin SIP (Single In-line Package), it features a compact footprint of 0.884" x 0.085" (22.45mm x 2.16mm) and a low-profile 0.195" (4.95mm) seated height, making it suitable for space-constrained designs. The ±100ppm/°C temperature coefficient and 50ppm/°C resistor-ratio drift enhance stability across operating temperatures, while the 200mW power rating per element ensures durability in demanding environments.
