ERZ-C20EK471Y is a Type 2 Varistor belonging to the TVS - Varistors, MOVs family. It has a thermoplastic encapsulation and uses surface mount technology.
Varistors are voltage-dependent nonlinear resistors (VDRs). They are used to provide protection in circuits, and can also be used as a form of damping. The value of the resistance of the varistor depends on its voltage rating, and it is also known as a voltage-dependent resistor due to its non-linear behavior. Varistors are used extensively in electrical circuits to protect against voltage spikes, radio frequency interference (RFI) and overvoltages.
The ERZ-C20EK471Y Varistor has a rated voltage of 20V, a thermal stability rating of -30 to +85°C, an electrical stability threshold rating of 7.2V, and a peak pulse voltage rating of 6.5V. It has a capacitance range of 1-6 pF and a capacitance tolerance rating of 0.5pF.
The working principle behind a varistor is simple. When a voltage arrives that is below the varistors rated voltage compared to ground, the varistor is essentially an open circuit, with very little current passing through it. When the voltage is raised above the rated voltage, the varistor then acts like an ohm’s law resistor, allowing current to pass through it to ground.
As soon as voltage drops below the rated voltage of the varistor, the current flows in the opposite direction, away from ground, causing no harm. This provides protection from voltage spikes and RFI in circuits. The ERZ-C20EK471Y Varistor works in exactly the same way, and can be wired into circuits with other components to provide protection.
The applications for ERZ-C20EK471Y Varistor are vast and include protection of AC lines, DC control circuits, electronic circuits, and audio and video systems. Varistors of this type are often used in applications such as medical equipment, telecommunications, industrial automation and consumer electronics, where protection from voltage spikes and RFI is paramount.
In summary, the ERZ- C20EK471Y Varistor is a Type 2 Varistor belonging to the TVS - Varistors, MOVs family. It has a thermoplastic encapsulation and uses surface mount technology. Its rated voltage is 20V, with a thermal stability rating of -30 to +85°C, an electrical stability threshold rating of 7.2V, and a peak pulse voltage rating of 6.5V. It has a capacitance range of 1-6 pF and a capacitance tolerance rating of 0.5pF. Its main purpose is to provide protection from voltage spikes and RFI in circuits, and is used in applications such as medical equipment, telecommunications, industrial automation and consumer electronics.
