Power Ring Technology

The ring shape (annular form factor) provides extremely low internal losses (ESR) within the film and also provides for the purest form of interconnect symmetry which can dramatically lower the inductive properties (ESL). These unique properties drive the leading edge electrical performance characteristics that the design engineer can take advantage of to develop systems with the highest level of performance and reliability.
