Iron oxides and oxyhydroxides are widespread in nature and play an important role in many geological and biological processes. They are used as iron ores, pigments, catalysts, and in thermite, and occur in hemoglobin. Iron oxides are inexpensive and durable pigments in paints, coatings and colored concretes.
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.
