Transformers Transformers Pulse Transformers and Modules for LAN Applications & Cases Sep. 2018 [Application Note] How to Use NTC Thermistors for Inrush Current Limiting TDK has an extensive lineup of inrush current limiting NTC thermistors available. This article describes various example applications of these products, used for ICL (inrush current limiting) purposes to easily and effectively suppress inrush current. When power is first applied to electronic devices such as switching power supplies and inverters, an instantaneous current with an abnormally high peak will flow through them.<br> This is known as “inrush current” and if not addressed, can lead to problems such as semiconductor element failure or reduced service life of smoothing capacitors. However, our inrush current limiting NTC thermistors can provide protection against this phenomenon to prevent such undesirable effects.
