Overview
The AICO Electronics CF 1/2 carbon film resistor is a precision fixed resistor designed for general-purpose and industrial electronic applications. With a resistance value of 2.4 ohms and a 0.5W (1/2 watt) power rating, this component delivers stable performance across a wide range of circuit configurations. The ±5% tolerance ensures reliable current limiting, voltage division, and load balancing in power supplies, amplifiers, and control circuits. This bulk offering of 1,000 units per box provides excellent value for production environments, repair facilities, and stock replenishment.
