5 Reasons Why Thermal Measurements Make a Difference

5 Reasons Why Thermal Measurements Make a Difference

Amid all the promotion of solid-state superlatives – from data rate to feature size to LED light output – junction temperature is rarely discussed. That is because junction temperature (TJ) is an undesired but unavoidable side effect of high currents and switching speeds. A p-n junction, whether it is one of millions on a CPU chip or the only one within a power LED, generates heat. In the past two decades the industry has seen heat dissipation increase by orders of magnitude. While faster is better, faster is also hotter.

What are Roller Chains?

In any motion control system, a motor has to connect somehow to whatever the load is. This final connection can take many forms. Some of the most efficient ways to connect with the load are so-called direct drive methods, where the motor is directly coupled to the load. When this isn't feasible, other methods are available to couple the motor to the load. One of these is a roller chain. Roller chains are constructed like a typical chain link structure; that is, a series of cylindrical rollers connected by links.
