**Bourns follows the prevailing definition 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.
Specifications are subject to change without notice.
The device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time.
Users should verify actual device performance in their specific applications.

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