MF-MSMF020/60-2

The part number MF-MSMF020/60-2 corresponds to a series of surface-mount polymer positive temperature coefficient (PPTC) resettable fuses manufactured by Bourns, Inc. These resettable fuses are used to protect electronic circuits from overcurrent events by limiting the current flow, and they automatically reset once the fault condition is removed.

Key Features:

• Resettable Protection: The MF-MSMF020/60-2 series of PPTC fuses offer resettable protection, meaning they automatically return to their normal operating state once the fault condition is removed, providing continuous protection to the circuit.

• Polymeric Construction: These fuses are made of conductive polymer material, which exhibits a positive temperature coefficient (PTC) behavior. This means that the resistance of the material increases with temperature, limiting the current flow during overcurrent events.

• Surface Mount Package: The fuses are provided in a surface-mount package, making them suitable for automated assembly processes and compact designs on printed circuit boards (PCBs).

• Low Resistance in Normal Operation: During normal operation, the resistance of the PPTC fuse is low, allowing for the smooth flow of current through the circuit.

• Overcurrent Protection: When an overcurrent event occurs, such as a short circuit or overload, the PPTC fuse quickly heats up due to the increased current flow. As the temperature rises, the resistance of the polymer material increases, effectively limiting the current and protecting the circuit.

• Automatic Reset: Once the fault condition is removed and the PPTC fuse cools down, it returns to its low-resistance state, restoring the circuit to normal operation without the need for replacement.

• Voltage Rating: The MF-MSMF020/60-2 series typically has a specific voltage rating, indicating the maximum voltage that can be applied across the fuse.

• Current Rating: These fuses also have a current rating, specifying the maximum current that can safely flow through the circuit without triggering the overcurrent protection.

Applications:

• Electronic Circuits: Used in a wide range of electronic circuits, including power supplies, battery chargers, USB ports, and communication devices, to protect against overcurrent events.
• Consumer Electronics: Integrated into consumer electronic products such as smartphones, tablets, laptops, and home appliances to safeguard sensitive components from damage caused by excessive currents.
• Automotive Electronics: Found in automotive electronics systems to protect critical components from short circuits and overloads, including in-vehicle infotainment systems, engine control units (ECUs), and lighting systems.
• Industrial Equipment: Deployed in industrial machinery and equipment for overcurrent protection in motor drives, control panels, and automation systems.
• Telecommunications: Used in telecommunications equipment and networking devices to ensure reliable operation and prevent damage from overcurrent conditions.
• Medical Devices: Integrated into medical equipment and devices for patient monitoring, diagnostic imaging, and treatment systems to ensure patient safety and device reliability.
