Varistors, Surge Absorber/Metal Oxide Varistors NV Construction
1. Insulation coating
2. Electrodes
3. Varistor element
4. Lead wire
 
 
Features
 
• Varistors own two- way symmetries and can absorb positive and negative surges.
• Flame retardant epoxy resign (UL94V-0) is employed for the
outer coating.
• The max peak current has developed about 2 times and the max.energy about 1.5 times in comparison with the existing products.
• Products with lead free inner connect solder meet EU-RoHS requirements .
 
Applications
 
• Measures for inductive lightning surges of those equipment that are connected to d.c.and a.c.lines.
• Absorption of surge voltages from inductive load of motors,relays,etc. and protection of semiconductor elements from excessive voltages.
