4609X-101-472LF – BOURNS

Overview

The Bourns 4609X-101-472LF is a high-performance 8-element bussed resistor network designed for precision signal conditioning and impedance matching. Its critical operational characteristic lies in the tight ±2% resistance tolerance across all elements, ensuring consistent current division and voltage scaling in complex circuitry. A key design consideration for engineers is managing the thermal dissipation; while each element is rated for 200mW, exceeding this in high-density applications can lead to increased resistance drift and reduced network lifespan, necessitating careful PCB layout and airflow analysis.
