WFH90L2K7JE

Chassis Mount Resistors

The WFH90L2K7JE is a type of chassis mount resistor that is commonly used in electronic equipment and components. It is an inexpensive and reliable device that can be easily installed without any complicated procedures. The WFH90L2K7JE is a resistor with a maximum power rating of 90 watts and a resistance value of 2K7 Ohms. It is an axial mount resistor and is typically mounted on a chassis using two simple screws or sometimes four, depending on the size of the resistor and the type of chassis.

Application Field:

The WFH90L2K7JE is mainly used in the electronics industry for applications where circuit protection is necessary. It is used to protect the circuit from possible damage caused by over-current, short circuits, and other hazardous conditions. This resistor can also be used to control the current flow in a circuit, which helps to reduce the power wasted due to voltage drop and current loss.The WFH90L2K7JE is also used in LED lighting applications, as it helps to maintain the voltage and current to the LED fixtures, which result in higher efficiency and better performance of the LED lighting system. It is also used as a voltage divider, which means it divides the voltage into two parts, one part is the load current and the other part is the supply voltage.

Working Principle

The WFH90L2K7JE works in a simple way. When a current flows through the resistor, a proportionate amount of voltage is dropped across it. This voltage drop is proportional to the amount of current flowing through the resistor. The resistor dissipates the power from the current as heat energy, which then dissipates into the air surrounding the resistor. The heat that is generated is proportional to the amount of current flowing through the resistor, and thus can be used to control the current in the circuit.

The WFH90L2K7JE is a very reliable and cost-effective resistor that is used in many electronic applications. It is easy to install and maintain, and it can provide sufficient protection for a circuit against over-current and short circuits. The resistor can also be used to regulate the current in a circuit, which helps to reduce the amount of power wasted due to voltage drop and current loss.
