What to check for Passive components
A wound magnetic component is several materials at once: a ferrite or powdered iron core, enamelled copper wire, a bobbin and often a potting or varnish. The wire enamel and the varnish are formulations and are where candidate list substances turn up, not in the core. Ask for a declaration that itemises the construction.
What a usable RoHS declaration contains
- The part number and package variant covered.
- The issue date of the document.
- The directive revision, including the 2015/863 phthalate amendment.
- Every exemption claimed, by its number.
- A named signatory.
