Varistors, also known as Voltage Dependent Resistor (VDR) or Voltage Sensitive Resistor (VSSRs), are non-linear devices. They come in many different shapes, materials and sizes and are used for applications ranging from surge protection to impedance matching. A varistor acts as a voltage-variable resistor and its resistance decreases as the applied voltage increases. The V10E320PL1B is a 10mm disc-shaped varistor specifically designed to provide surge protection in commercial and industrial applications. In the simplest terms, the V10E320PL1B Varistor operates like a fuse or circuit breaker. Once the varistor reaches its rated breakdown voltage, it short-circuits, diverting the surge current away from the sensitive components and redirecting it to the common line. This helps protect equipment from damaging transient voltages. It is important to select the right varistor for the application, as different varistors have different voltage ratings and current ratings which are tailored for the application.The V10E320PL1B has a long history of reliable performance in surge protection applications. It is constructed of semi-insulating sintered zinc oxide, with two 17.5mm diameter terminals. It has a breakdown voltage of 320 V (±10%), a maximum current rating of 4KA (8/20μs impulse current waveform), and a maximum energy rating of 32J (8/20μs impulse current waveform). With its small size and low profile, it is suitable for use in low-profile circuit boards.The V10E320PL1B is typically used in low-voltage electronic applications such as consumer electronics, automotive electronics, and industrial-grade equipment. In consumer electronics, it is often integrated into AC/DC power supplies, PC boards, household appliances, and entertainment systems to protect against lightning strikes or power surges. In automotive electronics, it helps protect car alarm systems, navigation systems, and other electronics from rising voltage levels caused by engine start-up, jump-starting, or short circuits. In industrial applications, the V10E320PL1B can be used to protect high-end industrial equipment such as cranes, power controllers, and automation systems from voltage spikes.The working principle and application fields of the V10E320PL1B can be summed up as follows: it is a 10 mm disc-shaped varistor designed to provide surge protection in commercial and industrial applications by short-circuiting once the varistor reaches its rated breakdown voltage of 320 V. It is primarily used for low-voltage applications such as consumer electronics, automotive electronics, and industrial supplies but is also suitable for high-end industrial applications where a high level of surge protection is required.
