DC Application Varistor Design Guide. 3 www.littelfuse.com. About the AUMOV Series Varistor. The AUMOV Series Varistor is designed for circuit protection in low voltage (12VDC, 24VDC and 42VDC) automotive systems. This series is available in five disc sizes with radial leads with a choice of epoxy or ...

GDTs, MOVs & Fuses: Selecting the Appropriate Circuit Protection ...
MOVs can be placed in series with GDTs. ▫ MOV will help cut off the follow current and allow GDT to turn off. ▫ During surge event, MOV will clamp and conduct first into a low impedance state ; then GDT will break-over and create the arc. ▫ When

Modeling Metal Oxide Varistors (MOV) in Short Circuit ... - Siemens
An important design issue of series capacitors in transmission lines is their overvoltage protection. A widely used protection scheme based on metal (zinc) oxide varistors (MOV) has proven to be very effective and reliable. MOVs present a nonlinear resistance characteristic that is approximated by fundamental frequency ...

The burning issue of metal oxide varistors and how to stop thermal ...
I was saw the three blue disc MOVs soldered across the L-PE, N-PE and L-N, but no short circuit or thermal protection. The BS standards in socket strip design has no reference to the MOV inside, my socket strip had no neon/ indicator light either so I could not tell if the power was on or not and I could not tell if the MOV was ...

temperature sensor
Temperature Sensor

Temperature sensing is a different sensing resistor chip package inside the probe, commonly used temperature sensitive components are: thermocouple, platinum resistance, thermistor and so on. Temperature sensing customers in the design and styling, we need to select sensitive chip used, the probe dimensions and material, type and temperature of the wire. After the chip welding wire, After the probe is filled and encapsulated, a complete sensor device is formed, and the production process takes several hours. My products through: SJ 20722-1998, GJB 7396-2011, GJB 2433A-2011, ISO / TS16949: 2009 certification. ......Including: ntc temperature sensor, ptc temperature sensor, Pt100 temperature sensor, water temperature sensor, car sensor, ds18b20 sensor.

Thermistors are a class of sensitive components, divided into positive temperature coefficient thermistor (PTC) and negative temperature coefficient thermistor (NTC) according to temperature coefficient. Typical characteristics of the thermistor are temperature sensitive and exhibit different resistance values at different temperatures. Our thermistors accord: JB / T9476-1999, JB / T 9474-1999 standard ...... include: ntc, ptc, SMD thermistors, thermistor power type, resettable fuse, Motor protection thermistor, etc.

Varistors are resistor device having a nonlinear volt-ampere characteristics, mainly used for over-voltage clamping circuit when subjected to pressure, the excess current sink to protect sensitive devices. The main material is the metal oxide (MOV, Metal Oxide Varistor), which contains ceramic particles consisting of zinc oxide particles and a small amount of other metal oxides or polymer spacings. Varistor referred to as VDR, varistor called "surge absorber", sometimes referred to as "surge suppressor. Now widely used "zinc oxide" (ZnO) varistor, its main material has divalent elements zinc (Zn) and hexavalent elemental oxygen (O) formed.

resettable fuse
Resettable fuse
Resettable fuse is an over-current electronic protection components, can replace the ordinary current fuse. Traditional fuse over-current protection, can only be protected once, burned to be replaced, while the Resettable fuse with overcurrent / overheat protection, automatic recovery dual function. Polymer polymer PPTC and ceramic CPTC two kinds of Resettable fuse two, according to the package can be divided into two types, lead plug-in and SMD two. Can also be divided according to the voltage 600V, 250V, 130V, 120V, 72V, 60V, 30V, 24V, 16V, 6V and so on. ..... Product Certification: CCC, CQC, ce, UL, ROHS, TUV, VDE, RU, pse, FCC, IEC and CB ...
