By Bourns Inc. 45
Bourns introduces the 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’ 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 a 0805 package.
The primary applications for these products are PC motherboard port protection, USB memory modules, and wearable devices. These devices have been designed to protect against both overcurrent and overtemperature events up to rated limits within the applications.
