About Power wirewound resistors

Power wirewound resistors are resistors that are made by winding a wire, typically made of a high-resistance material such as nickel-chrome or manganin, around a core. These resistors are designed to handle high power levels, typically in the range of watts to kilowatts. They are often used in power electronic circuits, such as in power supplies, motor drives, and other high-power applications.


Power wirewound resistors are characterized by their power rating, which is the maximum amount of power that they can dissipate without overheating. They are also rated for their resistance value, tolerance, and temperature coefficient of resistance (TCR).


Power wirewound resistors are available in a range of physical sizes, from small axial leaded resistors to large chassis-mounted resistors. They are also available in a range of resistance values, from a few ohms to several megaohms.


Power wirewound resistors have several advantages over other types of resistors, including their high power handling capability, high precision, and low inductance. However, they are generally more expensive and larger in size compared to other types of resistors.
