**Bourns follows the prevailing defi nition of “halogen free” in the industry. Bourns considers a product to be “halogen free” if (a) the Bromine (Br) content is 900 ppm or less;
(b) the Chlorine (Cl) content is 900 ppm or less; and (c) the total Bromine (Br) and Chlorine (Cl) content is 1500 ppm or less.
Specifi cations are subject to change without notice.
Customers should verify actual device performance in their specifi c applications.

Notes:
• MF-NSMF models cannot be wave soldered. Please contact Bourns for
hand soldering recommendations.
• If refl ow temperatures exceed the recommended profi le, devices may not
meet the performance requirements.
• Compatible with Pb and Pb-free solder refl ow profi les.
• Excess solder may cause a short circuit, especially during hand soldering.
Please refer to the Multifuse® Polymer PTC Soldering Recommendation
guidelines.
