adapted for coating resistive material on a base

Introduced: July 1974

Full Title

Full titles differ between systems:

IPC:

Apparatus or processes specially adapted for manufacturing resistors > adapted for coating resistive material on a base

CPC:

Apparatus or processes specially adapted for manufacturing resistors (providing fillings for housings or enclosures H01C1/02; reducing insulation surrounding a resistor to powder H01C1/03; manufacture of thermally variable resistors H01C7/02, H01C7/04) > adapted for coating resistive material on a base

IPC and CPC are identically structured here. All 4 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1974.
