METAL OXIDE VARISTOR, NV SERIES
Tama is supplying Transient Voltage Surge Suppressors, Metal Oxide Varistor, NV series. Multilayer Chip, Disc and Compound
types are available. UL recognized. Wide applications : Computer, Office equipment, Telecommunication equipment, Test and
Measurement equipment, Audio and Visual equipment, Other consumer products, etc.
In selecting the Varistor
For most applications, please select a five-step process.
1. Determine necessary steady-state voltage rating.
2. Establish transient enegy absorbed by varistor.
3. Calculate peak transient current through varistor
4. Determine power dissipation requirements
5. Select a model to provide required voltage-clamping
characteristic
