ARC Technologies, of Amesbury, Massachusetts USA has appointed Kemtron as the exclusive distributor for its magnetic and lossy foam absorbers for the UK.
The ARC magnetic absorber product line combines the highly effective energy absorption properties of iron with the high performance physical characteristics of flexible elastomer.
Finely milled iron powders and specialised fillers are blended in exacting ratios with such substrate materials as silicone, urethane, nitrile or neoprene rubber to create flexible EMI absorption sheets with thickness ranging from 0.25 to 6.4mm.
Lossy foam from ARC is a family of low-density, high-loss flexible EMI absorbers designed to solve a wide range of interference control problems easily, quickly and cost-effectively.
Using proven formulas, ARC Technologies combines refined carbon powders with binding agents.
The absorbent mixture is then precisely integrated into an open cell, reticulated polyurethane foam structure.
Because each step in ARC's production process is precisely controlled, performance repeatability is assured.
By varying the thickness and loading, ARC magnetic absorbers can be frequency-tuned to the specific application.
These space saving, thin materials are formulated to provide excellent attenuation and mode suppression at frequencies as low as 650MHz and as high as 40GHz.
Many are rated UL94V0 and are suitable for outdoor and harsh environmental applications.
