4309R-101-102 Description

The 4309R-101-102 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 features a 1kΩ resistance per element with a tight ±2% tolerance, ensuring reliable performance in precision circuits. The array operates within a ±100ppm/°C temperature coefficient and offers a 50ppm/°C resistor-ratio drift, making it stable under thermal stress. With a 200mW power rating per element and a 4.95mm max seated height, it balances power handling and space efficiency. The 4300R series is REACH-compliant and ideal for industrial and commercial applications requiring consistent resistance matching.
