What is the failure mode and failure mechanism of the resistor
Failure mode refers to various failure phenomena and their manifestations. Failure mechanism is the physical, chemical, thermodynamic or other process that causes failure. Then what are the failure modes and failure mechanisms of the resistor? Let's take a look.
1, open circuit: the main failure mechanism is the resistance film burned, large area off, basic fracture and lead cap and resistance body off, etc. We have Glenair-180-043M here.
2. The resistance drift exceeds the specification: the failure mechanism is manifested as defects or degradation of the resistance film, movable sodium ions in the matrix, poor protective coating, etc.
3, lead fracture: failure mechanism for resistance body welding process defects, welding spot pollution, lead mechanical stress damage, etc.
4. Short circuit: the failure mechanism is silver migration, corona discharge, etc.
The above content is the resistor several main failure modes and failure mechanism of the relevant content. I hope to help you to understand the resistor, need resistor and other electronic components of friends. Welcome to consult us oh.
