Through Hole Resistors are electrical components that limit the current flow in an electrical circuit. The most common type of Through Hole Resistor is a “fixed” wire-wound resistor, which consists of a coil of resistance wire wound around a cylinder or cylinder-shaped core. The material used for the core and/or the wire itself determines the amount of resistance provided. The type of wire also plays an important part in the selection of a suitable Through Hole Resistor for a particular application. Other types of Fixed Through Hole Resistors available include film resistors and carbon composition resistors.

The WW3FT250R is a wirewound, Through Hole Resistor that has a circular, four-terminal configuration. The device is constructed with a ceramic core, and a silver-plated copper alloy wire-wound around the core. The WW3FT250R is designed to provide a low-resistance path for current in an electrical circuit, thus allowing high current capacity at lower voltage levels.

The primary application of the WW3FT250R is for impedance matching in circuits that require moderate to high current levels and frequencies. These include power supplies, motor control circuits, audio amplification units, and even complex digital systems. The device has a rated operating temperature of -55°C to +150°C, and its cylindrical shape ensures a low contact resistance. In addition, the WW3FT250R has a high overload protection of 15W max, and is available in resistance values ranging from 0.01 Ohms to 10K Ohms.

The working principle of the WW3FT250R is similar to that of any other Through Hole Resistor. When current flows through the device, electrical resistance is generated due to the resistance wire inside the device. This resistance reduces the current flowing through the device, and the higher the resistance value, the lower the current that can pass through.

The WW3FT250R is designed to be used in applications where low power loss and high current capacity are required. It is also designed to withstand higher overloads than other Through Hole Resistors, and is perfect for use in harsh environments. As such, the WW3FT250R is an ideal choice for many types of cooling and low-resistance systems, as well as for applications involving high voltages and/or high frequencies.
