Chassis Mount Resistors

WFH90L5K0JE Application Field and Working Principle

Chassis mount resistors are a type of resistor installed on the open chassis of a metal frame, usually in some outdoor environment to withstand the temperature and vibration. The series of WFH90L5K0JE is such a chassis mount resistor with a unique application field and working principle.The most important application field for WFH90L5K0JE chassis mount resistors are in the automotive industry, where they are used to control engines, brakes, steering systems, and vibration dampening for certain vehicle components. This series of resistors is designed to work in harsh environment because of its exquisite construction and super durable shell which can resist vibration and humidity. It can also operate under high temperature up to 180℃ and provide excellent electrical isolation performance.The working principle of WFH90L5K0JE chassis mount resistors is based on ohm’s law. This series of resistors uses electrical resistance to create a voltage drop across its terminals. The electrical energy is dissipated in the form of heat energy when the current passes through the resistor. This means that the power dissipation is proportional to the square of the current. There are other factors that can affect the power dissipation such as environment temperature, type of materials used to construct the resistor, and the resistance value of the resistor which can be altered with a variable resistor.WFH90L5K0JE chassis mount resistors also come with a variety of features to adapt to different applications and environments. For example, this series of resistors comes with a wide operating temperature range and a variety of materials with different resistivity values. It also comes with a built-in thermal protection feature which prevents the resistor from overheating even under extreme conditions. In addition, this series of resistors also has good electrical noise suppression and electrostatic protection features, which makes it perfect for automotive applications.In summary, WFH90L5K0JE chassis mount resistors are specifically designed for applications in the automotive industry where they can withstand harsh conditions and provide excellent electrical isolation performance. Its operating principle is based on ohm’s law, and its features also provide safety for operation even in extreme conditions.
