Typical Response Time
Select varistor Varistor is a pressure limiting protection device. Can absorb excess voltage, protection of sensitive components in the circuit. There are many reasons for choosing a varistor.The response time of the varistor is ns level, its response speed, to meet the electronic circuit over-voltage protection requirements. Varistor is mainly used in transient overvoltage protection, similar to the voltammetric characteristics of a semiconductor regulator. Its protection characteristics, impact resistance characteristics of long life, working voltage life, stable performance. Varistor is widely used in household appliances and other electronic products, for over-voltage protection, lightning protection, suppression of inrush current, absorption peak pulse, voltage limiter, high voltage interrupter, noise reduction, the protective effect of semiconductor components and the like. What is the varistor The main material of the varistor is the metal oxide (mov), it contains ceramic blocks consisting of zinc oxide particles and a small amount of other metal oxides or polymers. A resistive device having a non-linear voltammetric characteristic, varistor referred to as vdr, the varistor is called a "surge absorber" sometimes referred to as "surge suppressor. Now the "zinc oxide" (zno) varistor, its main material has divalent elements zinc (zn) and hexavalent element oxygen (o) formed. Mainly used in the circuit to withstand overvoltage when the voltage clamp, absorb the excess voltage to protect sensitive devices. Characteristics of varistor Variable resistance voltage range: 18v-1800v A variety of surge capacity: standard, high surge, Ultra-high surge High current handling and energy absorption capacity Monomer flow can reach 70ka or even higher Fast response time fast Low leakage current Applications: power systems, surge suppressors, security systems, motor protection, automotive electronics systems, household appliances.

Zinc oxide is a versatile inorganic compound widely recognized for its numerous industrial and consumer applications. It is primarily known for its use as a white pigment in paints, sunscreens, and cosmetics, owing to its excellent UV-blocking properties and opacity. In addition to its role in pigmentation and sun protection, zinc oxide is utilized in the rubber and ceramics industries as a reinforcing agent and in the manufacturing of various chemical products, including zinc-based chemicals and pharmaceuticals. Its versatility, non-toxic nature, and ability to offer both aesthetic and functional benefits make zinc oxide a valuable and widely used compound in diverse fields.

We offer a wide plethora of Zinc in many forms including LME registered and non registered Special High Grade Ingots and Jumbos, cathodes, dust, foil, granules, powder, pieces, anodize activated powder, shot, and a mossy form. Zinc is a bluish-white, lustrous metal. It is brittle at ambient temperatures but is malleable at 100 to 150°C. It is a reasonable conductor of electricity, and burns in air at high red heat with evolution of white clouds of the oxide. Plating thin layers of zinc on to iron or steel is known as galvanizing and helps to protect the iron from corrosion.
