Cases That Protect Against EMI: Part 2

Designed cases to shield electronics from EMI.
Aluminum case attenuates EMI, 8 to 12 GHz.

Electromagnetic Interference (EMI) can affect electronics, disrupting timing circuits and corrupting signals. If sufficiently powerful – perhaps a pulse from a nearby radar installation – it can induce damaging voltage surges in wiring. There’s even evidence of EMI damaging the read/write heads of hard drive storage units. Continue reading

Modern electronics are very vulnerable to Electromagnetic Interference (EMI), sometimes called Radio Frequency Interference (RFI).  It’s not just lightning strikes, whose destructive potential is well known.  Radar pulses, radio and microwave emissions, cellphones, wireless routers, and the humble microwave oven can affect microprocessor-based systems.  It disturbs timing and corrupts data.
