Chassis Mount Resistors: WFH330L27RJE Application Field and Working Principle

Chassis mount resistors are one of the most common electronic components found in virtually any electronic circuit. They are used to dissipate power and limit current flow, which greatly benefits the overall performance of the circuit. The WFH330L27RJE is an ultra precision resistor and is commonly used for medical equipment, automotive audio systems and communications equipment. This article describes its application field and working principle.

Application Field

The WFH330L271JR fits into the Ultra Precision Resistor family and is a metal film resistor that complies with IEC61558-2:2012. It is intended for use in applications where high stability and accuracy is required. It has a wide resistance range, from 1Ω to 10MΩ, and is suitable for use in medical equipment, automotive audio systems and communications equipment. Due to its high precision, it is able to actively monitor changes in the external environment and prevent them from causing performance issues in electronic circuits.

Working Principle

Chassis mount resistors work based on the basic ohm’s law. When current is supplied to the resistor, a voltage drop is created across it. This voltage drop results in energy being dissipated because some of it is converted to heat. Therefore, a chassis mount resistor can be used to limit the current that flows through the electrical circuit, thus safeguarding its components. It can also be used to reduce the power that is required and prevent overloads which may cause damage. By using a precision resistor, like the WFH330L27RJE, the voltage drop can be accurately determined, allowing the electrical circuit to be more efficient and reliable.

Conclusion

The WFH330L27RJE is an ultra precision resistor that is suitable for use in medical, automotive and communication applications. Its working principle is based on the ohm’s law, in which current passing through the resistor causes a voltage drop across it. This results in energy being dissipated as heat, which limits the amount of current that flows through the circuit. Finally, a precision resistor, like the WFH330L27RJE, allows the voltage drop to be determined with great precision, which ensures the maximum performance of the electronic circuit.
