WebThin Film Resistor Definition: The resistor which uses a thin film resistive layer is known as the thin-film resistor. This layer is arranged on top of a ceramic base. As compared to the thick film resistor, the thickness of this resistor is very thin approximately 0.1 microns. WebA new approach to obtaining piezoelectric polymeric films based on the isotactic-polypropylene (i-PP) using corona discharge with the energy of 45 W·min/m2 was presented. Detailed analyses with Atomic Force Microscopy (AFM) led to the conclusion that the surface quality was the important factor influencing the possibility of charging the i-PP …
