Overview
The Yageo CFR-50JB-52-2K2 is a standard through-hole axial carbon film resistor rated at 2.2 kilohms with a 1/2W (0.5W) power dissipation and ±5% tolerance. This resistor is widely used in analog circuits, signal conditioning, and general-purpose electronics. The carbon film construction offers a proven balance of cost-effectiveness and performance, making it suitable for educational projects, prototyping, and production repair work.
