Through Hole Resistors are one of the most common and important components of any circuit. The WHCR75FET is an example of such a resistor. It is a four-terminal through hole resistor and is designed to have a maximum rated power of 75 watts. It also features a low thermal resistance and a high mean time to failure (MTTF). This article will look at the application fields and working principle of the WHCR75FET.

The WHCR75FET is designed primarily for power circuit applications. It is capable of operating in a wide range of temperatures, from −55°C to 175°F, and is also moisture and temperature resistant. It is used in a wide range of applications, including power supply filtering, power line regulation, and current sense-resistor networks. Its low thermal resistance makes it ideal for controlling power distribution and protection of sensitive analog and digital electronic equipment.

The WHCR75FET employs several unique physical configurations that help it perform its various functions. These include a center tapped four electrode design, which helps minimize the effects of power line noise and supply ripple; a solid copper core covered by a flame retardant ceramic coating, which helps to provide thermal stability; and a stainless steel case, which helps to prevent corrosion. The resistors also feature crimped end contacts for a reliable connection.

The WHCR75FET works on the principle of thermal resistance. Thermal resistance is the opposition to the transfer of heat. In a resistor, it caused by the material of the resistor and the temperature of its components. Thermal resistance is measured in degrees Celsius. In the case of the WHCR75FET, it has a higher thermal resistance than most other resistors, making it ideal for handling power in high-temperature environments.

When the WHCR75FET is applied in a circuit, it works by converting the applied voltage into a current. The current then passes through the four electrodes, which are temperature-resistant. The current is then limited by the resistor’s thermal resistance and is converted into voltage, which in turn is then regulated by the resistor’s power rating. This process is known as a voltage regulator. In applications where the current is too great for the WHCR75FET to handle, it will shut down, thus protecting the circuit.

Overall, the WHCR75FET is a reliable and effective through hole resistor. Its unique design, thermal resistance, and power rating make it an ideal choice for controlling power in a wide range of applications. It is also resistant to moisture and temperature, making it appropriate for use in a wide range of environments. Therefore, if you are looking for a dependable resistor for your power circuit needs, the WHCR75FET is an excellent one to consider.
