The MF-MSMC035-2 is a resettable fuse, specifically a Polymeric Positive Temperature Coefficient (PPTC) device, manufactured by Bourns Inc. These devices are designed to protect electronic circuits from overcurrent conditions. When an overcurrent event occurs, the PPTC's resistance increases dramatically, limiting the current flow and protecting the downstream circuitry. Once the fault condition is removed and power is cycled, the device resets to its low-resistance state.

Applications

• USB ports: Protecting USB ports and connected devices from overcurrent damage.
• Computer peripherals: Protecting printers, scanners, and other peripherals.
• Battery packs: Preventing overcurrent conditions in battery packs.
• Game consoles: Protecting sensitive electronic components in game consoles.
• General electronic equipment: Providing overcurrent protection in a wide range of electronic devices.

Features

• Resettable functionality: Automatically resets after the overcurrent condition is removed.
• Low resistance: Minimizes voltage drop during normal operation.
• Compact size: Allows for integration into small electronic devices.
• Fast tripping time: Quickly limits current during overcurrent events.
• Agency approvals: Meets industry safety standards.

Benefits

• Overcurrent protection: Prevents damage to electronic components caused by excessive current.
• Reduced downtime: Automatic reset minimizes downtime compared to traditional fuses.
• Improved reliability: Protects against component failures caused by overcurrent conditions.
• Simplified maintenance: Eliminates the need to replace blown fuses.
• Cost-effective solution: Provides reliable overcurrent protection at a competitive price.

The MF-MSMC035-2 has a hold current of 0.35A and a trip current of approximately 0.7A. It is designed to operate over a wide temperature range. This PPTC device is an essential component for ensuring the safety and reliability of electronic circuits.
