The MSMF020/60-2C is a Multifuse PPTC Resettable Fuse from Bourns. It is designed to protect electronic circuits from damage caused by overcurrent faults. These resettable fuses, also known as polymeric positive temperature coefficient (PPTC) devices, increase in resistance rapidly when an overcurrent condition occurs, limiting the current flow and preventing damage to sensitive components. Once the fault is cleared and power is removed, the device cools down and returns to its low-resistance state, restoring normal circuit operation.

Applications

• Consumer Electronics: Protecting power ports and internal circuits in devices like smartphones, tablets, and laptops.
• Computer Peripherals: Safeguarding USB ports, FireWire ports, and other I/O interfaces on computers and peripherals.
• Industrial Equipment: Providing overcurrent protection for control circuits, sensors, and communication interfaces in industrial environments.
• Telecom Equipment: Protecting sensitive circuitry in network devices, routers, and modems.
• Battery Packs: Preventing overcurrent and short circuit conditions in battery packs used in portable devices.

Features

• Resettable Functionality: Eliminates the need for manual fuse replacement after an overcurrent event.
• Compact Size: Allows for easy integration into space-constrained applications.
• Low Resistance: Minimizes voltage drop and power dissipation during normal operation.
• Fast Trip Time: Quickly responds to overcurrent conditions, limiting the duration of the fault current.
• Surface Mount Design: Facilitates automated assembly processes and reduces manufacturing costs.

Benefits

• Enhanced Circuit Protection: Prevents damage to sensitive electronic components from overcurrent faults.
