Specialized Resistors are widely used in a variety of applications. One such example is the ERA-V27J680V resistor, a varistor that is designed to protect a circuit from power spike transients. This article will explore the application field and working principle of the ERA-V27J680V resistor.

The ERA-V27J680V resistor is a varistor designed for discrete applications, such as in circuits requiring transient overvoltage protection. The resistor is constructed from zinc oxide and is capable of withstand high current values. The ERA-V27J680V has a wide operating voltage ranging from 6.8V to 27V, and is rated for a current of up to 6A. The resistor also has a high surge-current capability, making it well-suited for protection against power spike transients.

The working principle of the ERA-V27J680V resistor is based on the concept of voltage dependent resistors. When the applied voltage is below its threshold level, the resistor acts as a normal resistor, with a nominal fixed resistance. Above this threshold, however, the resistance of the resistor decreases rapidly with increasing voltage, thus creating a varistor. This means that the ERA-V27J680V can absorb large amounts of current when the voltage exceeds its threshold, thus protecting the circuit from damage.

The ERA-V27J680V is primarily used in applications requiring transient overvoltage protection. Examples of such applications include power supplies, motors, and other devices that may be susceptible to damage from power surges. The resistor is also frequently used in low-voltage electronic circuits, such as microcontrollers, because of its low internal capacitance.

The ERA-V27J680V resistor is also well-suited for use in circuits requiring noise suppression. This is because the resistor is able to absorb any noise generated by the circuit before it reaches the sensitive parts of the circuit. In addition, the resistor has a high power rating, making it capable of handling large transient currents without damage.

The ERA-V27J680V resistor is also a very robust component, with a long operating life. The resistor is capable of withstanding a range of temperatures, from -40°C to +85°C, providing reliable protection over a wide range of operating conditions. The resistor also has a high fail-safe rating, meaning it can still operate even when its maximum working conditions have been exceeded.

In summary, the ERA-V27J680V resistor is a specialized resistor designed for use in discrete applications requiring transient overvoltage protection. The resistor is also capable of providing noise suppression and has a long operating life. The resistor is rated for a wide operating voltage range and a high surge-current capability. This makes the ERA-V27J680V resistor well-suited for use in a variety of applications.
