The MF-PSMF035X-2-N9 is a resettable fuse, part of the Polymeric PTC (PPTC) series from Bourns Inc. These fuses are designed to protect electronic circuits from damage due to overcurrent conditions. Unlike traditional fuses, PPTC devices reset automatically after the overcurrent condition is removed, making them ideal for applications where frequent overcurrent events are expected.

Applications:

• Portable Electronics: Protection for charging circuits, data lines, and power inputs in smartphones, tablets, and other portable devices.
• USB Devices: Overcurrent protection for USB ports and peripherals connected to computers and other devices.
• Rechargeable Battery Packs: Protection against overcurrent and short-circuit conditions in lithium-ion and other rechargeable battery packs.
• Industrial Equipment: Circuit protection in industrial control systems, sensors, and other electronic equipment.
• Automotive Electronics: Protection for low-voltage circuits in automotive applications, such as infotainment systems and control modules.

Features:

• Resettable Overcurrent Protection: Automatically resets after the fault condition is removed, eliminating the need for fuse replacement.
• Compact Size: Small form factor allows for easy integration into space-constrained applications.
• Fast Trip Time: Quickly responds to overcurrent events, limiting the duration and severity of the fault.
• Low Resistance: Minimal impact on circuit performance during normal operation due to low on-state resistance.
• Agency Approvals: Complies with industry safety standards, such as UL, CSA, and TUV.

Benefits:

• Enhanced Circuit Protection: Prevents damage to sensitive electronic components from overcurrent events.
• Reduced Downtime: Automatic resetting reduces downtime associated with replacing blown fuses.
• Lower Maintenance Costs: Eliminates the need for fuse replacement, reducing maintenance expenses.
• Improved Product Reliability: Provides reliable overcurrent protection, enhancing the overall reliability of electronic devices.
• Safety Compliance: Meets industry safety standards, ensuring the safe operation of electronic equipment.

Specifications:

The MF-PSMF035X-2-N9 is characterized by its hold current, trip current, maximum voltage, and maximum interrupt current. The hold current represents the maximum current the device can carry without tripping. The trip current is the current at which the device will trip and limit the current flow. The maximum voltage and interrupt current specify the maximum voltage and current the device can safely handle during a fault condition. The operating temperature range is typically between -40°C and +85°C.

The Bourns MF-PSMF series provides effective overcurrent protection in a small, resettable package, making it a popular choice for a wide range of electronic applications.
