Inrush limiting resistors Inrush limiting resistors of a few Ohms or less in series with the AC line can address a problem with AC-DC converters where a large surge current may occur as the device powers up and the bulk storage capacitors initially charge. One...

Powering LED’s With Resistors Efficient and reliable operation of LED lighting is dependent on the right choice of current-limiting resistor. in many situations the necessary ballast resistor is likely to dissipate several Watts of power. This not only dictates...

Pulse Withstanding Resistors Determining the right pulse handling capabilities for a particular application is not always easy. Dealing with inrush current is different than dealing with transient suppression, for example. For pulses of up to five seconds, the...
