I used to work for a telecom UPS company and we used data on lighting
that I think was compilied from the National Weather Service. We used
this data because there was such a strong correlation between lightning
activity and incidence of power outages. Florida was definitely the
highest in
Richard,
It is my understanding that the FDA requires any product incorporating a
laser to be registered with the CDRH. I have a similar situation with a
remote we manufacture that incoporates a laser as a pointing device.
Even though our supplier has the laser registered, we must still
register
This seems to be a rather morbid subject, but here is my theory.
Human skin is somewhat of an insulator. Once this barrier is broken
down very low voltages can cause lethal currents. When people are in a
tub the skin barrier is broken down (through body cavities?) and the
body becomes a low enou

I posed this question to the group a few weeks back. See the archive
postings for July 28 and 29 for responses. I also did research and
could not come up with any written requirements for stainless steel. It
seems to just be a commonly accepted practice.

Most of our hard failures during ESD testing has been SCR type latch-up
with all makes of CMOS Devices. See Fairchild Semiconductor Application
Note 600 (AN-600) for a pretty good discussion of CMOS latch-up.

We have a new display panel design that requires a a small switcher for
power. The end product must meet Class B emissions. We are planning
on using the Linear Technology LT1376 IC which contains the control
circuitry and switch. It operates at 500KHz and is rated at 1.25 amps.
Has anyone had a
Dear Fellow Members,
We have a Mil-Spec requirement on one of our products that requires
chemical resistance to DS-2. Does anyone know what DS-2 is?
Thanks

Items 2 and 4 are probably correct. It is a very specialized subject
that most compliance people do not deal with. You have a list of 10
questions that are quite general like "are water fittings inherently
unsafe?". These probably require detailed answers that take some
research. Most qu
Dear Fellow Members,
We have a plethora of plastic subassemblies, produced by outside
vendors, that are received and stocked in our factory. We must keep
certs of flammability on file for each shipment of every plastic part to
satisfy UL, CSA, and TUV factory inspectors. This involves sorting an
