4309R-101-102LF

4309R-101-102LF Description

The 4309R-101-102LF 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 range, with a resistor-ratio drift of 50ppm/°C, making it stable under thermal stress. Its 200mW power rating per element and 4.95mm seated height suit space-constrained applications. Compliant with ROHS3 and REACH standards, it is ideal for industrial and consumer electronics requiring robust, long-term reliability.

4309R-101-102LF Features

• High-Density Integration: 8 resistors in a 22.45mm x 2.16mm footprint, reducing PCB space.
