First of all, the lowered distortion offered by the internal-bypass design will improve
audio/video performance. Each MultiCapTM is made with up to ten parallel bypass sections
optimized into a single unit. A 1 microfarad MultiCapTM, for example, is made up of ten 0.1 s, and
these act as internal by-passes. Our tests have shown that each internal bypass significantly
reduces the parasitics - inductive and resistive qualities - of the capacitor, thereby reducing
Second, using the internally bypassed MultiCapTM saves the space and money required for
external bypassing. No other capacitor available can offer this. In fact, we recommend external
bypassing only on the very large values of MultiCapTM - above 3.0 microfarads, and then only for
those designs in which extreme refinement of the upper frequencies is an important factor.
Third, the MultiCapTM was designed and patented by Richard Marsh, then working at the
Lawrence Livermore National Laboratory, for high-speed pulsed-power applications. This design
is new in concept and solves many audio capacitor problems. Our measurements back us up in
this, and so do our customers' responses. They tell us the MultiCapTM increases the neutrality &
clarity of their products.
Worried about expense, for lower-cost applications? We'd like to call your attention to the
cost-effective MultiCapTM-ll, a single-bypass version of the design that offers significant
performance improvements over standard metalized caps - both unbypassed and
bypassed, at about the same price as many varieties popular in audio and video designs.
See the 2-ppmfx section of our catalog.
Today we offer five series of MultiCapsTM of different materials, sizes, configurations, and prices. All
share the internal bypass design that has proven so successful. One or more of these MultiCapsTM will be suitable for any application in audio and video designs.
REL's Electronic Components Division offers its engineering and laboratory services to MultiCapTM
customers. We can make specialized measurements of most pertinent
parameters for the characterization of analog audio, digital, and video
equipment: network analysis; Z analysis; signal analysis; spectrum
analysis; linearity; acoustical analysis; color analysis for video
video products (ISF qualified). Our laboratory covers the frequency
spectrum from sub-audio through video.
