WW3FTR220 Application Field and Working Principle Through hole resistors are components used to measure resistance in an electric circuit. The WW3FTR220 resistor, in particular, is a power resistor manufactured by the Belgium-based W+W company and is used in various applications across many industries. This article outlines the application fields, working principle and benefits of the WW3FTR220. Application FieldsThe WW3FTR220 resistor is most commonly used in applications that require a high degree of precision in electrical control and measurement. The resistor can handle a maximum power of 220 watts and a maximum frequency of up to 8 kHz, which makes it suitable for use in applications like electronic fuel injection systems, oscillator circuits, high power motor control, printing machines, audio amplifiers, switching power supplies, telecommunications equipment, and automotive systems. Furthermore, the resistor also has a wide temperature range of -65 °C to +135°C, meaning it is suitable for use in high-temperature environments.Working PrincipleThe unique design of the WW3FTR220 resistor makes it particularly suitable for use in power applications. The resistor comprises two parts: the first is the metal oxide film, which is a thin layer of resistive material, and the second is a ceramic body, which acts as a protective casing. When voltage is applied to the resistor, it creates a voltage drop across the metal oxide film. This voltage drop creates heat, which is dissipated by the ceramic body. This means that the resistor is able to work efficiently even when dealing with high currents and powers. BenefitsThe WW3FTR220 is a high-precision resistor that can handle heavy power loads efficiently. It is also an economical solution as it offers excellent power dissipation, good precision and accuracy, and resistance stability over its operating temperature range. Furthermore, the resistor also offers excellent long-term reliability, which means it can be used in applications where precision and power are needed for long-term use. Overall, the WW3FTR220 is an ideal choice for applications where accuracy and control are required for long-term use. It is a cost-effective solution that can handle heavy power loads with precision and accuracy over its wide temperature range. Furthermore, its long-term reliability and stability make it a reliable option for various industries.
