Engineer's Survival Kit - Free!

When this Engineer's Survival Kit appeared in my RF Cafe Twitter feed, I though it was a gag item, but it turns out to be a very useful experimenter's resource for mitigating EMI/RFI issues, provided at no cost by ARC Technologies - at least for now. It comes with a variety of RF absorber materials in different thicknesses and form factors that address frequencies from 50 MHz through 110 GHz.

The sheets of foam-based material are good, but what caught my attention - and is the reason I bothered to post this promo - is the heat-shrink tubing product. I have never seen EMI/RFI shielding in that format before. It should be very effective in preventing interference leakage into an assembly via a power and/or signal cable connector port or bulkhead feedthrough. It won't be much help if the interference is already on the wire before it hits the shielding, but it will complete the integrity of the Faraday shield action of a metal enclosure.
