4816P-2-473LF – BOURNS

Overview

The Bourns 4816P-2-473LF is a high-density 15-element bussed thick film resistor array designed for precision signal conditioning and impedance matching in demanding electronic systems. Its key operational characteristic is the consistent 47kΩ resistance value per element, coupled with a tight ±2% tolerance and 80mW power rating per element, ensuring predictable performance. A critical design consideration is the trade-off between element density and thermal dissipation; while compact, engineers must carefully manage power dissipation to prevent exceeding the per-element rating, which could lead to parametric drift or premature failure, especially in high-temperature automotive environments.
