Home / ROHS

Many OEMs must comply with the new requirements set forth by the European Union regarding the Restriction of Hazardous Substance in Electrical and Electronic Equipment (ROHS). This directive, known as ROHS, aims to protect the environment by restricting the use of certain hazardous substances (including lead) in new equipment. ROHS requires that from 1 July 2006 new electrical and electronic equipment will not contain lead, mercury, cadmium, etc.

In compliance with ROHS, and in an effort for our customers to accommodate their ROHS requirements, AAC has begun supplying lead free surface mount chip resistors as of September 2004. The resistor series, CR,CJ, CRN, CT, CTL, and CRL meet the requirement of current ROHS directive 2011/65/EU. During the interim, you will be able to differentiate the tin/lead from the lead free by the lot number. All our parts are still compatible with 260 degree C soldering, and can be ordered using the lead-free termination code. Those parts which are lead free will have a lot number ending in the letter “L.” AAC has chose to supply parts in this manner to reduce the cumbersome task of creating all new part numbers for lead free products.
