Varistors, or Variable-Resistance Transient Suppressors, are designed to protect electronic equipment against voltage transients. MLVA02V05C033-R is a type of Varistors developed by Littelfuse. It is a multilayer metallized varistor with an operating voltage of 250 volts. This product is used for surge protection in AC line applications.

The MLVA02V05C033-R varistor is a nonlinear, bidirectional, voltage-dependent, symmetrical component that provides a low impedance path when the voltage exceeds its designated voltage breakdown rating. These varistors are designed for AC line protectors in appliances, lighting fixtures, and motor’s protection circuits. It also provides passing overvoltage protection and clamping under ovservoltage protection.

The operating principle of MLVA02V05C033-R is based on the nonlinear property. When the amplitude of an impulse is above the breakdown voltage, the varistor will start conducting current and a low impedance path will be formed, allowing large amount of surges to bypass from line-to-ground.

The varistor features a rated operating voltage of 250V, peak impulse current of 1.0 kA, and clamp time of 4 ns. This product can be used in a wide range of AC line applications. It has an acceptable surge current up to 2.5 kA and provides reliable over-voltage protection for AC circuits. It also provides excellent protection against fast transients, such as those due to lightning strikes. This protection is increased by the use of a varistor with a low clamping ratio, such as the MLVA02V05C033-R.

In addition, the varistor features a high surge energy rating up to 140 joules, which makes it ideal for high-current surge events. Its maximum operating temperature is 125°C, making it suitable for high temperature environments and for long-term protection. The varistor also features low leakage current and high peak current capability. The high over-voltage protection capability and low capacitance makes it suitable for high voltage applications.

In conclusion, the MLVA02V05C033-R is a varistor that provides low impedance over-voltage protection for AC line applications. It features a high surge energy rating, low leakage current, and high peak current capability. It is ideal for high voltage applications where fast transients, such as those due to lightning strikes, need to be protected against. It is suitable for use in a wide range of AC line applications, and is capable of providing reliable over-voltage protection.
