Varistors, more commonly known as voltage-dependent resistors (VDRs), are one of the three components that make up the TTVS family. They have the ability to massively increase their electrical resistance when they are subjected to surges in voltage, thus protecting the electronic circuitry they’re connected to from the affects of such surges. MOVs, on the other hand, are metal oxide varistors, which act somewhat in the same way as a varistor, though they are specialised to protect against electrical surges of a particular momentary duration.

The B72547E3200K000 is a metal oxide varistor, or MOV, that is specifically designed to protect electronic circuitry against momentary Voltages of up to 3,200V, and maximum energy dissipation of 1,000 Joules. This makes it well-suited to the rigours of electricity in high-end industrial, engineering and medical settings, where surges of power are often unavoidable, and the resulting damage could prove disastrous. It is a thermally and mechanically stable device, meaning it maintain its resistance over a broad range of operating temperatures, as well as its physical properties.

The B72547E3200K000 performs two main functions. The first is that it greatly reduces voltage peaks by clamping the excess energy to ground. This is done by the varistor and MOVs within, which both provide a grounded resistance pathway for excess current—much in the same way as a circuit-breaker does. This reduces the chance of any catastrophic or otherwise damaging surges being passed through the circuitry, as the device will effectively “trip” and draw it away from the power source. The second function it serves is as a network filter, where it reduces the amount of noise and interference over the line in order to ensure stability when transmitting data.

In terms of size, the B72547E3200K000 is a cylindrical device that measures 7.5mm x 10mm. It has a rated current of 40A, which means it is capable of handling any surge current up to that amount—ensuring any damage is kept to a minimum. It is manufactured with very high quality standards, meaning that it is free of any impurities and possesses excellent electrical and thermal characteristics. As such, it makes for an ideal choice in demanding applications, such as lighting systems and uninterruptable power supplies.

In conclusion, the B72547E3200K000 is a high-end, reliable and effective metal oxide varistor, or MOV, which is designed to protect sensitive electronic circuitry from the affects of momentary voltage peaks up to 3,200V. The device is thermally and mechanically stable, has a rated current of 40A and is suitable for a variety of demanding industrial, engineering and medical applications. As such, it is an excellent choice for those seeking reliable and effective protection from unpredictable surges in power.
