Through Hole Resistors are a class of resistors that are used in electrical circuits to reduce the voltage of current flowing through it. WVM5JBR510 is a through-hole resistor that can provide excellent performance for applications requiring a reliable over-voltage protective device.

Application Field

The WVM5JBR510 is a precision-engineered resistor designed for use as an over-voltage protection device in applications such as automotive, industrial, and consumer electronics. This type of resistor is primarily used to limit the maximum voltage that can be delivered to a circuit. It can also be used in power supply voltage regulation, over-voltage protection of communication equipment, and other applications requiring reliable over-voltage protection.

Working Principle

The WVM5JBR510 is designed to automatically limit the voltage to the expected levels when the voltage exceeds the preset values. It is constructed with a PTC element and a resistor element series connected in parallel. When the input voltage exceeds the preset range, the PTC element will conduct current, thus reducing the voltage and providing over-voltage protection for the circuit.

The resistor element is designed to control the rate of voltage drop for a specific setting. It is composed of two parts with the first one being the resistor matrix and the second one being the equivalent resistance. The resistor matrix is composed of a series of resistors interconnected in a certain order such that when the input voltage exceeds the predetermined value, the voltage drop is controlled by the resistor matrix. The equivalent resistance is used to define the output voltage for a given input voltage.

The WVM5JBR510 works in combination with a protection circuit for protection and current regulation. In this setup, the resistor element will trigger a current limiting protection circuit when the input voltage exceeds the preset range. The current limiting protection circuit ensures that the current is limited to the allowable levels.

Conclusion

The WVM5JBR510 through-hole resistor is an ideal device for applications that require reliable over-voltage protection. Its precision-engineered construction and carefully designed components ensure that it can provide precise voltage regulation and over-voltage protection. It is a cost-effective solution for applications in automotive, industrial, and consumer electronics industries.
