Welcome to STK ELECTRONICS Film Capacitors

STK Electronics began manufacturing film capacitors in Cazenovia, NY in 1975. Our first product offering was a range of close tolerance capacitors featuring film-foil polypropylene, a dielectric best suited for these applications. Over the years, we have continually developed and designed many additional products, providing the extensive choice of capacitors featured today.

All STK Electronics capacitors are RoHS compliant.
