Overview
The 10D121K is a varistor made by RUILON in a 插件 package with 2 pins. 1.5nF@1kHz 10.8J 100V 108V~132V 2.5kA 200V 75V 插件 Varistors ROHS.
PCBKit's library has its KiCad symbol (Device:Varistor, from KiCad's library) and its footprint (EasyEDA_Cloud:RES-TH_L12.5-W5.1-P7.50-D1.2-S2.20, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C233245).
