A driver pulling up to a fast charger wants a high current DC charge fast, and the station has to deliver it again for the next vehicle within minutes, session after session, day after day. Every new charging session places stress on the charger's power electronics as circuits energize and capacitors charge. Vishay's PTCEL High Energy series PTC thermistors limit the resulting inrush current surge, helping protect the charger through years of repeated high power cycling.
Behind every fast charge is The DNA of tech.®
