4609X-101-223LF – BOURNS

Overview

The Bourns 4609X-101-223LF is a high-density, bussed resistor network designed for precision signal conditioning and impedance matching in demanding electronic systems. Its critical operational characteristic is the tight ±2% resistance tolerance across all eight elements, ensuring consistent current division and voltage scaling. A key design consideration for engineers is managing the thermal dissipation; while each element is rated at 200mW, careful PCB layout and airflow are essential to prevent exceeding this limit in high-density applications, thereby maintaining the ±100ppm/°C temperature coefficient and overall circuit integrity.
