V48MLA1210LNHAUTO is a EPV type metal oxide varistor (MOV) designed specifically to protect direct current circuits such as automotive, communications, industrial, and solar applications. The device is constructed from a proprietary formulation of non-linear metal oxide material encapsulated in a cylindrical-shaped case. When subjected to excessive electrical stress, such as voltage spikes or transient overvoltages, the MOV conducts current away from the protected circuit.

The V48MLA1210LNHAUTO is built to handle a continuous voltage rating of +/-50 V (DC) and a 400 V clamping voltage, as well as a 100 A nominal current rating. This unit features a wide temperature range: -55°C to +125°C and a wide frequency range: 0 to 1 MHz. The unit is supplied in a flat, low profile package, which makes it easier to integrate into applications that need both space and protection.

This type of varistor can be used to protect automotive, communications, industrial, and solar applications. In automotive applications, it is used to protect components from damage due to current surges caused by voltage transients, such as those resulting from jump starting a car battery. In communications, it can be used to protect electronic components from damage due to overvoltage due to lightning strikes. In industrial and solar applications, V48MLA1210LNHAUTO is used to protect DC power supplies, as well as critical circuit components, from damage due to power interruptions, overvoltages, and other sources of potential damage.

The working principle behind V48MLA1210LNHAUTO is based on the fact that metal oxide varistors are non-linear in nature. When subjected to a high voltage, such as an overvoltage, the resistance of the MOV is reduced. As the voltage rises, the resistance of the MOV decreases, providing a path for the excess current to dissipate, which in turn protects the delicate electronics from damage. This is known as the “clamping effect.”

The V48MLA1210LNHAUTO is designed to provide reliable protection against overvoltage damage in a variety of automotive, communications, industrial, and solar applications. Its wide temperature range and low profile design make it an ideal choice for these types of applications. By using this type of varistor, components are protected against damage caused by voltage surges, lightning strikes, overvoltages, and power interruptions, which can save time and money by preventing costly repairs and replacement.
