Fuses for power protection, Part 2
Part 1 of this FAQ explained fuse basics. Although fuses are simple in principle, selecting the most suitable fuse for the application is more complicated than it may seem initially. Q: What are the key questions to ask when selecting a fuse? A: These are just a few of the considerations: What is the normal […]
Fuses for power protection, Part 1
Fuses are the oldest and easiest-to-understand circuit-protection components, with several common schematic representations (Figure 1). The function of the fuse is simple and clear; in the case of an overcurrent condition, the fuse “opens” (or blows, in common parlance) which thus stops the flow of current. Despite their simplicity, fuses have subtleties and considerations that […]
Six considerations for better circuit protection
In an electronic system where the power source can be connected the wrong way round, protection should be considered to prevent damage to the circuitry. Most electronic circuits don’t like the power supply being reversed. However, there are other eventualities you could protect your circuit or system from temperature, humidity, excess current or excess loading, […]
