ERZ-E08B221CS Application Field and Working Principle

TVS- Varistors, MOVs are a type of electrical component that helps protect sensitive electronic components from electrical transients. The ERZ-E08B221CS is a type of varistor that can help prevent electrical shorts and spikes that can damage the sensitive components in modern electronic equipment. In this article, we will discuss the application field and the working principle of the ERZ-E08B221CS.

Application Field:

The ERZ-E08B221CS is a two-terminal non-linear electronic component that is used to protect against electrostatic discharge, voltage transients, and overvoltage conditions. It is most commonly used in the safety circuit of electronic and communication equipment.

The ERZ-E08B221CS can also be used in applications where signal protection is required, such as in power supplies, data processing systems, and computers. It can also be used in consumer electronics such as TVs, cell phones, and other devices.

Working Principle:

The ERZ-E08B221CS is a two-terminal non-linear electronic component. It is a metal-oxide varistor (MOV) with a special design. The two terminals of the varistor consist of a zinc-oxide pellet between two layers of an electrically conductive material. The two terminals are connected together by an internal oxide layer. This layer helps increase the resistance of the MOV and provides insulation between the two terminals.

When the voltage across the terminals of the ERZ-E08B221CS exceeds the varistor\'s breakdown voltage, it causes a current to flow through the device. This current creates a heat that vaporizes the oxide layer, increasing the resistance of the MOV and limiting the flow of current.

The ERZ-E08B221CS is designed to meet stringent safety requirements and is UL listed. The electrical ratings of the varistor are 2.5µA, with a maximum peak surge current rating of 20A and a peak pulse power of 400W.

The ERZ-E08B221CS is a robust and reliable component that can help protect your sensitive electronic components from damaging electrical transients. It is an ideal choice for safety circuits and power supplies. It is also an economical solution for protecting against electrostatic discharge, voltage transients, and overvoltage conditions.
