Through Hole Resistors, a commonly used electrical component, are a pre-manufactured device placed across a device or circuit to reduce current or ensure proper operation. One type of Through Hole Resistor is the WNAR75FE, which is an industrial power metal glazed resistor that is specifically designed to provide protection from overvoltage and overcurrent. Its application field and working principle will be discussed in greater detail in this article.

The WNAR75FE typically comes with a variety of features, such as a large power rating, an encapsulated construction, and adjustable tracking resistant operation. With a power rating of 100W, the WNAR75FE can be used in a wide range of applications that require heavy-duty power handling. Its encapsulated device is also highly resistant to moisture and other environmental factors. Furthermore, the WNAR75FE also comes with an adjustable tracking resistor operation feature that enables it to maintain a precise voltage level during operation.

In terms of its application field, the WNAR75FE is often used in industrial environments and power supplies. Its 100W power rating makes it suitable for use in motor controls, HVAC equipment, UPS systems, and other high-power circuits. In addition, the WNAR75FE also has the capability to protect against transient surges and voltage drops. This makes it ideal for use in electrical installations where the voltage is not stable or may experience sudden changes.

Regarding its working principle, the WNAR75FE operates like other metal glazed resistors, where its resistance is determined by the metal glaze (impedance) on its surface. The resistance of the WNAR75FE is adjustable, depending on the amount of glaze that is applied and the temperature of the environment in which it is being operated. This adjustable resistance allows the WNAR75FE to provide the resistance needed for protection against overvoltage and overcurrent.

In conclusion, the WNAR75FE is a metal glazed resistor specifically designed to provide protection from overvoltage and overcurrent in high-power applications. This device is capable of withstanding high currents and peak voltages and is suitable for use in a variety of industrial and power supply applications. Its adjustable resistance allows it to maintain a precise voltage level, which helps to protect the circuit from surges and voltage drops. The WNAR75FE is an invaluable component to have in any electrical system and should be installed properly for optimal protection.
