Chassis mount resistors are widely used for controlling of power and voltage in an electronic system. The WFH90L4R7KE is a type of chassis mount resistor that is suitable for low-power applications as well as high-power ones. It has a tolerance of 1%, making it very accurate for controlling power/voltage/current within a particular range.
The WFH90L4R7KE has a very efficient design, allowing for a low-profile design and minimal heat generation which makes it suitable for high-power applications. This design also offers excellent temperature capabilities and a low forward voltage drop which enhances its performance.
The working principle of the WFH90L4R7KE is based on the fact that it has two build in resistors that work in tandem. The first resistor is the static resistor, which is used to provide the necessary resistance to the circuit. The other resistor is an active (variable) resistor, which is used to adjust the voltage applied to the circuit. The two resistors are connected in series and can be adjusted separately to provide the desired result. This allows for precise power and voltage control within the circuit.
The application field of the WFH90L4R7KE is quite vast, as it can be used for controlling the power/voltage/current in various electronic and electrical systems. It is commonly used in automotive industry, consumer electronics, industrial process control, and various other sectors. It offers an optimal solution for precision power and voltage control as it is able to handle a wide range of power/voltage levels.
The WFH90L4R7KE is a highly reliable and accurate chassis mount resistor that can be used in a variety of power/voltage/current control applications. It has a compact design which allows for a low profile and minimal heat generation, making it highly suitable for high-power applications. Additionally, it offers excellent temperature capabilities and a low forward voltage drop, which makes it suitable for precision power and voltage control.
