RoHS Compliant

RoHS Compliant
Several EU directives( RoHS ,WEEE) are forcing manufactures to reduce respectively to avoid the usage of hazardous subatances in electronic devices.

For this reason, we guarantee that all products or parts intentionally do not contain the hazardous substances prohibited by RoHS directive : 2002/95/EC, SS-00259 Rev 4.

Several EU directives (ROHS, WEEE ( are forcing manufacturers to reduce respectively to avoid the usage of hazardous substances in electronic devices.

For this reason we need your cooperation and commitment with regard to the following questions:

1.Which lead free items can already be manufactured and delivered by your company in compliance to ROHS?

LAN Transformers POE Transformers Chip Inductors
a) Please let us have your detailed list of the available lead free items.
b) How has the „lead free marking "been implemented?
Means lead-free marking how (description)
yes no
on the label v Show the lead free logo and RoHS complaint in the reel and carton of label.
in the article description v   REMARK FOR LEADFREE PRODUCT
in the article number v   FOR LEAD FREE P/N + “LF”
2. Do you see any price and delivery changes for lead-free items ?
NO.If so, which items? Please list them in detail.
3. If your items are not yet lead free available, when will you be definitely in the position of being able to manufacture lead free items in compliance to ROHS?
>>Please let us have your detailed roadmap including the way of your planned „ lead free marking“ >>question 1b.
4. Are all your manufactured items (lead free and not lead free) already solderable with lead free soldering processes ?
5. Are all your lead free items as well solderable with the conventional Pb-soldering processes ?
6. If you modify some processes in order to comply with the RoHS directive, can you still fulfill the existing specifications?
YES.>>If not, please indicate what changes of specifications are planned.
7.We would like to receive all products according to the RoHS directive commencing latest 30. April 2004. Can you definitely fulfill this requirement?
YES.If not, please.
a) list all products that you deliver to us that will not comply with the RoHS directive.
b) what are the reasons.
c) what measures are planned (e.g. compliance later date, …).
8. If you modify some processes in order to comply with the RoHS directive, what measures will be taken in order to guarantee the reliability of the products?
