MULTIFUSE® PPTC RESETTABLE FUSES
MF1711
Bourns’ Multifuse Product Line Announces Additional
New Models to MF-USML Family of PPTC Resettable Fuses
Riverside, California - July 7, 2017 - The Bourns Multifuse Product Line is pleased to announce the
introduction of a series of new part numbers to the already successful MF-USML product family of surface
mount Polymer Positive Temperature Coefficient (PPTC) Resettable Fuses. The five additional new models
will now extend the maximum operating current of the MF-USML series from 1.75 A to 7.0 A.
Bourns’ low ohmic materials used in this product family have post trip resistance values as low as 13.5 mOhms
and initial resistance values as low as 1 mOhm. Such low resistance values help boost the current carrying
capability of these new devices. Bourns can now achieve a 7 A I
hold
model in a 1210 package (MF-USML700-2).
These compact MF-USML models use Bourns’ freeXpansion™ design that increases the performance of the
resettable fuse with:
n Higher hold currents (I
hold
) n Improved resistance stability
n Higher voltages (V
max
) n Smaller footprints
The primary applications for these products include PC motherboard port protection, USB memory
modules, wearable devices and battery protection for smart phones. These devices have been designed to
protect against both overcurrent and overtemperature events within these applications.
The new Model MF-USML Multifuse® PPTC resettable fuses are RoHS compliant* and UL recognized for
safety requirements, and are produced in Bourns’ TS16949 approved facility in Xiamen, China.
For additional details on these exciting new models, please contact your nearest Bourns representative.
