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. |
