4309R-101-152 Description

The 4309R-101-152 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 1.5kΩ resistance per element with a tight ±2% tolerance, ensuring consistent performance in precision circuits. The array operates within a ±100ppm/°C temperature coefficient and offers a resistor-ratio drift of 50ppm/°C, making it stable across varying thermal conditions. With a 200mW power rating per element and a low-profile 4.95mm seated height, it balances power handling and space efficiency. Packaged in tubes, this REACH-compliant, EAR99-classified component is ideal for industrial and commercial applications requiring reliable resistor networks.
