Through hole resistors are a type of resistor that are fixed to a circuit board or another substrate. A hole is bored through the hole and a metal tab, known as a lead, is inserted into the hole. It is then soldered into place by an electrical technician. The leads vary in length dependent on the size of the resistor and the application. The WW3FT220R is a type of through-hole resistor designed specifically for high power applications with its surface mount equivalent being the SMD.The WW3FT220R surface mount resistor is designed for a wide range of applications. It has an operating temperature range of -40°C to +105°C and a maximum voltage rating of 65V. It is also rated for a current of 22 amperes. It has an impressive power rating of 33 watts and can be used in many high-power electrical applications.The resistor works slightly differently to other resistors, as it is designed to limit the amount of current flow to the desired level, rather than absorb the current. This requires a more complex design, as the resistor needs to convert linear currents into heat. The resistor needs to be able to dissipate heat quickly and not be affected by temperatures that would degrade the performance of other resistors.The WW3FT220R resistor works by passing electrical current through a resistive material, usually an alloy such as nickel-chromium or copper-manganese. As the current flows through the resistive material, it experiences a resistance that reduces the current of the flow, thus providing the desired current limit.At high currents, the resistor becomes warmer, due to the energy being converted into heat. As the resistor is encased in a hermetically sealed package, the heat is not able to escape. In order to maintain high performance, the resistor needs to be kept cool, usually with a heat sink. The heat sink dissipates the heat away from the resistor, ensuring that it operates at a safe temperature and has a long life.WW3FT220R resistors can be used in a range of applications, including automotive, power supplies, lighting and industrial. The resistor is also designed to have a low inductance, making it suitable for applications such as power entry points, gate drives and DC-DC converters. Due to their high power rating and wide operating temperature range, they are often used in the power electronics industry.In summary, the WW3FT220R resistor is a type of through-hole resistor designed specifically for high power applications. It works by passing electrical current through a resistive material and then dissipating the heat away from the resistor. This ensures that the resistor is able to operate at its maximum power rating and has a long life. The resistor is also suitable for a range of applications, including automotive, power supplies, lighting and industrial.
