常见问题 - Lead-Free Information
Lead-free packages offered by Power Integrations feature lead-free solder finish using 100% matte tin (Sn). The lead-free packages meet the requirements of the European law on the Restriction of Hazardous Substances (RoHS), which mandates the removal of lead and other hazardous substances cited in the directive. All lead-free products have passed qualification testing for moisture sensitivity, solderability, and whisker growth. The lead-free surface mount products also comply with the joint IPC/JEDEC industry standard on reflow solderability (J-STD-020C).
Products with a lead-free finish are designated by an N-suffix to the package type in the order number and are available at no additional cost. Lead-free finish packages are PN (DIP-8), FN (TO-262), YN (TO-220), and GN (SMD-8).
* Note: Products are designated as Lead (Pb)-Free if they meet the following definition: "Components in which the lead (Pb) level in any of the homogeneous materials and the end product is less than 0.1% by weight."
