Just for reference though the California law is ONLY applicable to
electronics with display devices; and those displays have to have a diagonal
dimension of 4 inches or greater.

RoHS

Camille,

Regarding your last paragraph, both China and Korea do seem ready to accept
the EU's specific exemptions according to my discussions with them. However
we'll have to wait for the actual Catalog (in the case of China) and the
Ordinance of the Ministry of Environment (in the case of Korea).

California explicitly references EU RoHS and it's follow-ons in the law so
not only will the exemptions allowed in the EU be valid here, but California
seems to be taking our first step to membership in the European Union since
the European Court of Justice has jurisdiction over RoHS. ;o)

Cadmium in relay contacts helps harden the contacts and makes them last
longer in high-current / high inrush-current / significant power factor
relay applications. When I was looking at Cd-free replacements for relays
with cadmium contacts, I saw that in all cases relays with Cd-free contacts
had lower endurance & current ratings than relays in the same case with the
same coil that used cadmium contacts.

information like that was presented to the EU committees such that the use
of cadmium in relay contacts was granted an exemption. (Side note - if
anyone does know of any studies, I would really appreciate it if they could
forward the information to me.)
