> Is it safe to assume that this plastic material is anti-static? It is not. Static charge is sufficient to cause voltage overstress on some high-impedance MOS devices, but USB doesn't have any connector pins attached to high-impedance circuitry, only to transceivers ( the low impedance of the transceiver output circuit protects the input it's attached to). | |||||||||||||||||||
