**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.

## ~~**Storage Recommendations**~~ The recommended long term storage conditions for Multifuse[®] Polymer PTC devices are 40 °C maximum and 70 % RH maximum. All devices should remain in the original sealed packaging prior to use. Devices may not conform with data sheet specifications if these storage recommendations are exceeded. Devices stored in this manner have an indefinite shelf life. ## MF-SM SERIES, REV. U, 07/17 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. ## **MF-SM, MF-SM/33, MF-SM/60 & MF-SM/250 Series Tape and Reel Specifications** _NOTE: Effective December 1, 2010 (product date code V0), the cover tape was changed to the new 3M[™] Universal Cover Tape (UCT)._ |**Tape Dimensions**|**Tape Dimensions**|**Tape Dimensions**|**Tape Dimensions**|||**MF-SM030,**
