High voltage surge resistors
FEATURES
•
Excellent anti-surge characteristics
•
Stable characteristics to moisture
resistance even in high resistance
range.
SR25/37/37L/52
APPLICATIONS
•
CRT-RGB witch is used TV,monitor
•
Devices which need protection
surge voltage between power
preliminary and secondary.
DESCRIPTION
A metal glazed film is deposited on a
high grade ceramic body. After a
helical groove has been cut in the
resistive layer, tinned electrolytic
copper wire are welded to the end-
caps. The resistors are coated with a
brown and blue non flammable
lacquer which provides electrical ,
mechanical, and climatic protection.
