Varistors, also known as voltage dependent resistors (VDRs), are unidirectional semiconductor devices designed to help protect systems from transient voltages. They work by providing a low impedance path to ground when a voltage spike occurs in the system. The function of varistors is to protect sensitive electronic components from damage which may occur due to transient electrical overshooting and energy changes, making them a critical component in any electrical or electronics system.

AMCV-0402-5R5-C180N-T is a common type of varistor, designed to fit a 0402 package, with a 5.5-V maximum clamping voltage across a 180-ohm resistance. It has a maximum holding current of 70mA and can withstand clamp voltages between 40V and 200V. There are also several other versions of this varistor available, including a 5V max and 220V max versions.

AMCV-0402-5R5-C180N-T is primarily used in over-voltage and transients protection applications. In particular, it can be used in telecommunications and networking equipment to safeguard against inadvertent overvoltage events that may occur from power spikes, lightning strikes, and other sources. It is also suitable for use in consumer devices, such as laptops, desktops, tablets, phones, and other consumer electronics.

This varistor type works by allowing a small amount of current to flow through the resistor when the protected circuit is exposed to a transient voltage. When the voltage spike exceeds a certain threshold, the varistor responds by suddenly increasing its resistance. This in turn causes the two end terminals of the varistor to switch abruptly from low impedance to high impedance mode, effectively “shorting” the transient voltage. This process limits the amount of current that can be pushed into the protected circuit, thus helping to prevent any damage or disruption caused by the transient voltage.

AMCV-0402-5R5-C180N-T is an effective and affordable device designed to provide reliable and effective protection from transient voltage events. It is small and compact, making it suitable for use in a wide variety of electronic products, including mobile phones, tablets, laptops, and other consumer devices. This makes it a popular choice for designers looking to ensure optimal electronic protection in all their products.
