Through hole resistors come in a variety of shapes and sizes. In general, they consist of a small metal body which is connected to two metal leads. In applications where reliability is critical, or when two or more resistors must be electrically and/or mechanically interconnected, through hole resistors are often the best choice. The WNB10RFE is a type of through hole resistor that is primarily used for power quality applications.

The WNB10RFE is one of the toughest and most reliable through hole resistors available. It is characterized by a wide operating temperature range, high resistance stability under extreme temperature conditions, and excellent linearity and accuracy. The resistor body is constructed of nickel plated copper, and the leads are made of stainless steel which provides excellent corrosion resistance. The resistor has an epoxy coating which not only provides protection from vibrations, but also keeps moisture and dust away from the resistive element.

Applications of the WNB10RFE are typically found in power conditioning and control systems, high voltage power supplies, and in motor control circuits. It is often used to replace other type of power resistors such as wire-wound resistors, where increased reliability and accuracy are desired. The WNB10RFE is also frequently used in the design of power factor correction (PFC) systems due to its high load stability and accuracy.

The working principle of the WNB10RFE is based on the basic principles of electrical resistance. When an electric current passes through the resistor’s metallic body, some of the energy in the current is converted into heat energy. This heat energy is dissipated through the resistor’s body, resulting in a decrease in electrical energy. The amount of energy lost is determined by the resistor’s resistance value.

In order to ensure that the resistor values remain stable over a wide temperature range, the heat dissipated by the resistor needs to be managed carefully. This is accomplished through a combination of special heat dissipating materials, such as metal oxide layers, and an epoxy encapsulation. The special materials, when combined with the epoxy coating, provide excellent thermal dissipation while still maintaining the resistor’s electricalproperties.

The WNB10RFEthrough hole resistor is an excellent choice for power quality applications. It offers reliable performance under a wide range of temperatures and conditions, and its epoxy coating provides excellent protection from vibration and extreme environmental conditions. The WNB10RFE offers superior resistance stability and accuracy, making it a reliable choice for high voltage power supplies, power conditioning, and motor control systems, as well as for PFC systems.
