FOUNDER Vinod Bolaj
FROM THE FOUNDER

Four decades of capacitor engineering,
brought into sharper focus.

Four decades in capacitor engineering led me to a clear vision: to concentrate Marxelec on the applications where technical judgement and specialist experience matter most.

That focus now shapes our vision - to become the first name engineers call for special-application capacitors. We are building deeper capability across energy-storage and discharge systems, high-voltage DC applications, surge protection, induction-heating capacitors, PD-sensitive measurement and import-substitute development.

Our ambition is not simply to manufacture a broader range. It is to build a stronger engineering organisation-one capable of taking Indian special-application capacitor expertise to demanding customers worldwide.
