Title: Miniature encapsulated resistive network - has resistance material coated onto synthetic foil and sandwiched together for end contact connection
Inventor: SCHNEIDER WOLFGANG DIPL PHYS D
IPC: H01C13/02
Filed: 1980-09-22
Abstract: Miniature resistive or RC network construction with resistance valves in the megohm range and contained in a, typically, 5 mm package. Resistance material layers are coated onto a synthetic support foil and several are sandwiched together in a staggered formation. A contact layer is formed across the ends of the sandwiched resistance layers to form a contact with end terminal foils. The end foils are staggered to a greater degree than the resistive layers so that they form contact with only one contact layer and extend either up or down through an insulating compound sealing ends of resistive sections. Further synthetic material wafers interrupt the flow of end contact material to increase the resistive options available from the unit.
