<p>The prototype of all varistors is the V42MLA1206H, an essential device for protecting circuit boards from high voltage, over current and other form of electrical transients. It is a zinc oxide based non-linear Varistor with a working voltage range of -50V to +200V and a capacitance range of 0.05pF to 3.3nF.</p><p>Varistors are popular due to their ability to protect against overvoltage, overcurrent and short circuit conditions. A typical application of the V42MLA1206H would be the protection of a circuit board when exposed to power surges or lightning strikes. The device works by clamping any excessive voltage that is applied to the circuit board, preventing damage to the components. The V42MLA1206H is available in a range of capacitance and voltage ratings and can be easily installed on a circuit board.</p><p>The basic working principle behind the V42MLA1206H Varistor is that of a voltage dependent resistor. In this case the resistance is increased as the voltage across it increases. This in turn increases the amount of current being diverted away from the circuit when an overvoltage condition is applied.</p><p>The V42MLA1206H Varistor has a number of benefits when compared to other types of Varistors. These include low leakage current, high response time, and particularly low power dissipation. This device is geared toward low current applications, where it offers excellent protection against overvoltage, overcurrent and short circuits. It has a high voltage withstand capability as well as a wide operation temperature range.</p><p>The V42MLA1206H Varistor is an ideal solution for low voltage application, offering protection against overvoltage, overcurrent and short circuit conditions. It is a reliable device that is used in a number of industrial and commercial applications. It is capable of quickly responding to transient voltage changes, making it an ideal choice for minimizing any potential damage to a circuit board or system due to such events.</p>
