[PSES] AW: ROHS Lead Exemption Expires 2024 (e.g. metal film resistors)

Hi Elliott, you can check the legal status of RoHS exemptions at Implementation of the RoHS Directive (europa.eu). There you will find an Excel list for download that will show the curre

Hi Brent and the group. I agree as long as we stay under 8 KV. For 20 kV discharge, I would use a (easy to build) filter that slows the rise to that more like a real discharge. Nice repeatable contact discharge that more closely resembles reality. Doug Smith Sent from my iPhone IPhone: 408-858-

Re: [PSES] Resend of complete message on ESD thoughts

I'll jump in quickly to state my opinion: Contact discharge does not represent any "natural" mechanism I know of, but I prefer it because it seems to have the highest repeatability in revealing a device's vulnerability. -Brent, "If I can't be 'right', I at least want to be consistent about it

Re: [PSES] Resend of complete message on ESD thoughts

There are two good points about 61-4-2:the test results are repeatable and products that pass the tests rarely suffer from ESD failures in the field. But there are, even so, unresolved issues and doubts about the relations between the tests and actual ESD events. Because the present standar

Re: [PSES] Resend of complete message on ESD thoughts

Don't forget the seminal research done by WMKing on this topic. He was I believe the first to measure the fast response of an ESD event through a metal intervening object. Also, it is understood that the ESD test was a consensus output in an attempt to provide repeatability within test houses. King

[PSES] ROHS Lead Exemption Expires 2024 (e.g. metal film resistors)

Is the general consensus that the exemption will be extended or go into effect? I find it interesting that the truly lead-free resistors often sell for less than the old ones (probably less demand as BOM changes are slow) - This mes

Re: [PSES] Resend of complete message on ESD thoughts

Yes, 61000-4-2- is not very good, but while you are reluctant to share your knowledge with the committee, it is unlikely that anything will happen. == Best wishes John Woodgate OOO-Own Opinions Only www.woodjohn.
