Resistive voltage divider made of a resistive film material on an insulating substrate

摘要

A resistive voltage divider comprises at least a first (4) and a second (5) resistor, which are electrically connected in series and are made of a resistive film material (1) which is applied in form of a trace onto an insulating substrate (2). The divider's voltage ratio has a value between ten and one million. In order to improve the accuracy of the voltage divider, the at least first (4) and second (5) resistors are made of the same resistive film material (1), have a trace length above a corresponding specific trace length and have approximately the same trace width.
