< Table of content Ignition coils > E-mobility > Raising performance >


Improved endurance for ignition coils

Main features and benefits !! Impregnation of fine wire windings (30!m) !! Operating temperature 150-180°C / >1000 hrs !! Thermal shock / thermal mismatch (-40° / +140°C) !! High voltage resistance (up to 30 KV/mm) !! Crack resistance !! Adhesion to thermoplastic housing / bobbin !! Compatibility with integrated PCB !! Dielectric strength, dielectric constant



Improved endurance for ignition coils

Manufacturing process: vacuum potting !! Mass production => Short cycle times (10´000 parts per day and equipment) !! Fast filling (gaps 1 mm) !! Short curing (current 4 - 6hrs, future 0.5 - 2hrs)
