CAY16-560J4 – BOURNS

Overview

The Bourns CAY16-560J4 is a 4-element isolated resistor array designed for precision signal conditioning and impedance matching in compact electronic assemblies. Its critical operational characteristic lies in its consistent 56 Ohm resistance value across all elements, crucial for maintaining signal integrity in high-speed data lines. A key design consideration for engineers is the inherent trade-off between the 250 mW power dissipation per element and the need for thermal management in densely populated PCBs; exceeding this limit can lead to parametric drift and premature component failure, underscoring the importance of careful layout and thermal simulation.
