Two multifuse polymer ITC resettable fuse product models for battery applications: the MF-MSMC 190 and the MF-AAA from Bourns are designed to meet the sophisticated needs of today's growing portable equipment market. The MF-MSMC190 surface mount battery protector and the MF-AAA battery protector provide protection from potentially damaging overcurrent conditions caused by short circuits or overcharging in the battery packs that power products such as digital cellular telephones. Developed using polymer positive-temperature coefficient (PPTC) fuse technology, the Bourns multifuse battery protectors are distinguished from other circuit protection devices by their ability to reset automatically. The manufacturer says they are designed for ready implementation in high volume production battery applications and are not only instrumental in facilitating automated component placement but also feature a competitive price and low-profile design.
The MF-MSMC190 is designed for use in increasingly more complex digital cellular telephones that now also incorporate sophisticated electronics, such as power management ICs and charge controllers into their rechargeable lithium battery packs to monitor cell functions. Supporting the trend to place all the electronic components onto a PCB or flex-circuit inside the pack, the MF-MSMC190 also features a low 100°C trip temperature, a high 1,9 A hold current, 100 A maximum interrupt current and a 16 V rating to offer the best combination of safety, size, performance and efficiency.
