MSR25/37/37L/52
APPLICATIONS
•
CRT-RGB witch is used TV,monitor
•
Devices which need protection
surge voltage between power
preliminary and secondary.
DESCRIPTION
The multi layer metal film is 3 layers
deposited on a high grade ceramic
body. After that helical groove has
been cut by laser at 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.
