Varistors, or voltage dependent resistors (VDRs), are a type of electronic component that limit electric current and protect devices from electrical overvoltage. They work by limiting the voltage across an electric circuit, protecting sensitive devices in the circuit from voltage spikes. The B72210S0551K101 is a varistor specifically designed to protect against electrostatic discharge (ESD) or transient voltage spikes. In this article, we will discuss the application fields and working principles of this varistor.
The B72210S0551K101 varistor is designed to handle transient voltage spikes, making it particularly well-suited for a wide range of applications. Historically, this type of varistor has been used in the electronics industry, from automotive to consumer electronics and even military and aerospace applications. In the automotive industry, the B72210S0551K101 is used to prevent ESD damage to sensitive electrical components and to protect against transients caused by lightning strikes. In consumer electronics, it is used to protect components against voltage spikes caused by switching power supplies, power adapters or wall adapters.
Another application in which the B72210S0551K101 finds widespread use is in mil/aero applications. This type of varistor is used to provide surge protection against accidental electrical components being connected or disconnected from aircraft systems or other military vehicles. In addition to surge protection, the B72210S0551K101 also finds use in military and aerospace as a lightning protection device, ensuring that sensitive electronic components are not damaged by transient voltage spikes.
The working principle of the B72210S0551K101 varistor is fairly straightforward. It is an electronic component that is designed to absorb energy from electrical or electrostatic overvoltage events. When an excess voltage passes through the component, it activates the MOVs (Metal Oxide Varistors) which have been designed to absorb and dissipate the energy of the transient voltage spike.
The MOVs are composed of metal oxide or zinc oxide discs sandwiched between two metal electrodes. When the voltage exceeds the voltage rating of the varistor, the MOVs become conductive, allowing excess voltage to be diverted from the circuit. The dissipated energy is then transformed into heat, thus protecting sensitive components within the circuit.
The B72210S0551K101 varistor is specifically designed to provide superior protection against electrostatic discharge (ESD) or other transient voltage spikes in a variety of different application fields. This varistor uses a combination of metal oxide varistor (MOV) and zinc oxide varistor (ZOV) discs to provide reliable surge protection. It is also highly reliable, and is not prone to damage from overvoltage. As such, it is widely used in automotive, consumer electronics, military and aerospace applications.
