RoHS Compliance
   RoHS Compliant       Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ether. RoHS will become effective on July 1, 2006. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

   VWM       The maximum working voltage (VWM) is the continuous (DC) or peak voltage that can be applied to the device over the operating temperature range. When selecting a TVS, this voltage should be larger than the voltage of the device to be protected. Maximum working voltage is also known as standoff voltage.
