Rod resistors are a cylindrical type resistor that are used in both RF and microwave applications. They are thin film in nature and can be made of alumina, beryllium oxide, or aluminum nitride.The resistance range for rod resistors is generally from 10 ohms up to 500 ohms, and the resistive tolerances are generally 1%, 2%, or 5% with power ranges up to 75 Watts.
