THICK-FILM RESISTIVE ELEMENT Russian patent published in 1996 - IPC

FIELD: electrical engineering. SUBSTANCE: well- known structure of thick-film resistive element incorporating steel backing with insulating and protective glass-carrying layers placed in sequence between which resistive layer is positioned uses thick-film paste based on alkali-free glasses in the capacity of material of insulating and protective layers. Paste for insulating layer is based on alkali-free crystallizing glass and paste for protective layer contains alkali-free glass with ceramic filling agent. Thick-film paste based on nickel powder with addition of chrome powder or Ni-Cr alloy and glass binder is used as material of resistive layer. EFFECT: expanded application field, improved operational characteristics. 5 tbl
