MF-PSML SMD 0805 low ohmic resettable fuses

Bourns is pleased to announce the introduction of the new Model MF-PSML Series of Multifuse® polymer PTC resettable fuses. These 0805 (2012 metric) size surface mount devices are among Bourns’ smallest size resettable fuses to use Bourns’ new low ohmic PTC material.

The MF-PSML series has post trip resistance values as low as 25 mOhms and initial resistance values as low as 3 mOhms. Such low resistance values are also helping to boost the current carrying capability of these new devices. Using Model MF-PSML350-2, Bourns can now achieve a 3.5 A Ihold in an 0805 package.

The compact MF-PSML series uses Bourns’ freeXpansion™ design which increases the performance of the resettable fuse over conventional designs, with higher hold currents, higher voltage, improved resistance stability, and smaller footprints.
