SBE Quality Policy


technical papers Technology Overview

SBE offers several technologies to solve power electronic problems.

technical papers Technical Papers

Papers on low Trise, low ESR/ESL, extreme pulse current survival and significant capacitance density.

power ring technology Power Ring Technology

This proven technology provides extremely low internal losses (ESR) as well as the purest form of inter- connect symmetry which can dramatically lower inductance (ESL). These unique properties drive the leading edge electrical characteristics for the highest level of performance and reliability.

patented laser technology 105°C Coolant DC Link Capacitor

SBE developed a leading edge Film Capacitor technology for EV powertrain inverters and gathered over 3.5 Million unit hours of life testing data on these capacitors, which can operate in a 105°C coolant environment. With that knowledge, SBE developed an array of design tools, which can accurately characterize the performance of the Power Ring and other capacitors.

patented laser technology Patented Pulse Technology

A revolutionary way of controlling the typical failure mechanism of pulse capacitors.

patented laser technology Testing Capabilities

SBE has developed a number of testing methods to support its customers’ needs.
