4309R-101-820 Description

The 4309R-101-820 from Bourns Inc. is an 8-resistor bussed network array designed for precision applications in through-hole mounting configurations. With a compact footprint of 0.884" x 0.085" (22.45mm x 2.16mm) and a low-profile height of 0.195" (4.95mm), this component is ideal for space-constrained PCB designs. Each resistor in the array features a 82Ω resistance with a tight ±2% tolerance, ensuring consistent performance across demanding circuits. The device operates within a ±100ppm/°C temperature coefficient range, with a 50ppm/°C resistor-ratio drift, making it suitable for stable, temperature-sensitive environments. Packaged in a 9-pin SIP (Single In-line Package) and supplied in tubes, the 4309R-101-820 is REACH-compliant and classified under ECCN EAR99 for global compatibility.

4309R-101-820 Features

• High-Density Integration: Combines 8 resistors in a single SIP package, reducing board space and assembly complexity.
