About us


As an innovator of
film capacitor technology,
we  enable our customers
to optimize their own products
with the capacitor solution
specific to their needs.


Who are we?

SBE Inc., dba SB Electronics, designs and manufactures the most reliable Film Capacitor Products for today’s demanding applications. We have developed unique technology (patent pending) in pulse design and continue to introduce new technologies to support the Homeland Security, Electric Utility, Energy Efficient Lighting, Medical and Automotive/e-drive markets. Formerly a Sprague Electric company, the company has evolved from a supplier of high volume standard products to additionally providing application specific capacitor solutions. SBE will push the envelope of available technology and we are working constantly to create new technology as well.

While new technology is entering, we have not reduced our support of traditional products. We manufacture the well known Orange Drop® and 192P Pacer® Film Capacitor lines, both of which have reliably served the industry since 1959!

SBE continues to focus on expanding our product offerings. ALL of our products are supported by the comprehensive service you have grown accustomed to.
