LACQUER-ENCAPSULATED CARBON FILM RESISTER

摘要

The lacquer-encapsulated carbon film resistor comprises (a) a ceramic substrate; (b) a carbon film deposited over the entire surface of (a); (c) an insulating layer of Si3N4 deposited over the entire surface of the carbon film, only the electrical connection portions of the carbon film being uncoated; (d) metal electrode caps positioned tightly against the carbon film at the electrical connection portions; (e) current conductors welded to the caps to serve as leads, and (f) a layer of epoxy resin lacquer coated over the entire carbon film resistor assembly except the leads. The resistor is well protected from overloading and insensitive to electrochemical corrosion.
