High-voltage cylindrical film-type resistor and method of making it

摘要

A high-voltage cylindrical film-type resistor has cup-shaped end caps that receive the ends of the cylindrical substrate, each end cap having a convexly-radiused rim that has a radius of at least 1.5 mils in a plane containing the substrate axis. In accordance with the method, the stated radius is achieved by abrading, preferably tumbling.
