TVS - Varistors, MOVs are used in electronic devices to protect the circuits against the invasive attack of electrical surges.

The CG0402MLC-05LG is one of the more powerful devices of this type offered by Littelfuse, and typically they protect a wide range of equipment from transient voltage surges, both during normal operation and under electrical fault conditions.

This particular varistor is a simple type of metal-oxide varistor, with the majority of its components being a nonlinear metal-oxide power semiconductor material. The MOV works by storing energy when exposed to large input voltage surges, and then releasing this energy into the system’s main power output.

The nonlinear semiconductor material used in these varistors typically consists of two sub-materials; zinc oxide and manganese oxide. As most people know, the two materials are held together in a sandwiched configuration, with one material acting as the positive contact and the other as the negative contact.

The operation of the CG0402MLC-05LG is based on the fact that the semiconductor material gets "energized" when exposed to an electrical current. This energized material absorbs some of the energy from the electrical surge, thus relieving stress on the system\'s components. The energy stored in the MOV is released into a power output line, which reduces the current in the power output lines and prevents any further damage to the system.

The CG0402MLC-05LG is also rated for an operating voltage of 200V and a maximum current rating of 2.5A. This means that it is usable in a variety of systems, both low power and high power.

In summary, it is clear that the CG0402MLC-05LG is a powerful and reliable varistor that can protect a large range of equipment from surges and electrical faults. Its use of a semiconductor material means that it is extremely effective in absorbing and releasing energy as required, thus providing superior protection for electronic equipment.
