4310M-101-221 Description

The 4310M-101-221 from Bourns Inc. is a high-performance resistor network designed for precision applications. This 9-resistor bussed array features a 220Ω resistance per element with a tight ±2% tolerance, ensuring reliable signal conditioning and voltage division. Encased in a 10-pin SIP (Single In-Line Package), it offers a compact footprint of 0.984" x 0.085" (24.99mm x 2.16mm) and a seated height of 0.250" (6.35mm), making it suitable for space-constrained PCB designs. With a ±100ppm/°C temperature coefficient and 50ppm/°C resistor-ratio drift, it delivers stable performance across varying thermal conditions. The 250mW power rating per element and through-hole mounting ensure durability in demanding environments.
