Digi-Key, in collaboration with Ametherm, presents a PTM describing transformer protection from inrush current using the NTC thermistor. This will provide a problem statement describing the inrush ...

(Originally I posted this question on Electrical Engineering StackExchange site, but I was told that it is focused on EE design aspects rather than electronic/computer devices use aspects, hence ...

Matt Cuhadar from the Ametherm team answers a reader question about choosing the right type of NTC Thermistor to limit inrush current for capacitive applications. Matt Cuhadar is a key member of the ...

Acceptable ohm reading for a good current relay. One type of starting relay used on fractional-horsepower compressors is the current relay. This type of starting relay uses the initial high inrush ...

In the real world, components don’t work like we imagine they do. Wires have resistance, resistors have inductance, and capacitors have resistance. However, some designers like to take advantage of ...

What is a pre-charge circuit and what role does it play? The fundamental elements of a pre-charge circuit. Some basic best practices and where to find more information. A common challenge in systems ...
