The MF-MSMC050-2 is a resettable fuse, also known as a Polymeric Positive Temperature Coefficient (PPTC) device, manufactured by Bourns Inc. It is designed to protect electronic circuits from overcurrent conditions. These devices increase in resistance dramatically when subjected to an overcurrent, limiting the current flow and protecting the circuit. Once the fault is removed and power is cycled, the device resets to its low-resistance state.

Applications:

• USB Ports: Protection of USB ports in computers and peripherals.
• Portable Electronics: Protection of battery packs and charging circuits in smartphones, tablets, and other portable devices.
• Game Consoles: Overcurrent protection in gaming consoles.
• General Electronic Circuits: Protection against overcurrent in a variety of electronic circuits.

Features:

• Resettable: Automatically resets after the overcurrent condition is removed.
• Solid State: No moving parts, providing reliable performance.
• Compact Size: Small form factor allows for easy integration into electronic circuits.
• Low Resistance: Minimal impact on circuit performance under normal operating conditions.
• Fast Trip Time: Quickly responds to overcurrent conditions.

Benefits:

• Circuit Protection: Protects sensitive electronic components from damage due to overcurrent.
• Reduced Downtime: Eliminates the need to replace blown fuses, reducing downtime and maintenance costs.
• Increased Reliability: Solid-state design provides reliable and consistent performance.
• Cost-Effective: Provides a cost-effective solution for overcurrent protection.

Additional Details:

The MF-MSMC050-2 has a hold current of 0.5A and a trip current of 1.0A. The maximum voltage rating is 60V. The device is surface mountable and is available in a 1210 package size. The operating temperature range is -40°C to +85°C. It is RoHS compliant. The device's resistance increases significantly when the trip current is exceeded, limiting the fault current to a safe level.
