4609X-101-102 – BOURNS

Overview

The Bourns 4609X-101-102LF is a high-performance 8-element resistor network designed for applications demanding precise and stable resistance values. Its primary function is to provide a compact, integrated solution for multiple discrete resistors, offering a significant advantage in board space and assembly cost. A critical design consideration for such networks is the impact of thermal coupling between elements; while each element is rated at 200mW, in dense, high-power applications, careful layout is essential to prevent premature derating due to shared heat dissipation within the 9-SIP package.
