The MF-MSMF110L-2 is a resettable fuse, also known as a Polymeric Positive Temperature Coefficient (PPTC) device, manufactured by Bourns Inc. These devices are used for overcurrent protection in various electronic circuits. When an overcurrent condition occurs, the PPTC device increases its resistance, limiting the current and protecting the circuit. Once the overcurrent condition is removed, the device cools down and returns to its low-resistance state, effectively resetting the fuse.

Applications:

• USB Ports: Protection for USB ports on computers and peripherals.
• Portable Electronics: Battery pack and charging circuit protection in devices like smartphones and tablets.
• Disk Drives: Overcurrent protection in hard disk drives and solid-state drives.
• General Electronics: Overcurrent protection in various electronic circuits.

Features:

• Resettable Fuse: Automatically resets after the fault condition is removed.
• Surface Mount: Designed for surface mount assembly.
• Compact Size: Small form factor for use in densely populated circuit boards.
• Low Resistance: Minimal impact on normal circuit operation.
• Fast Trip Time: Quick response to overcurrent events.

Benefits:

• Overcurrent Protection: Prevents damage to electronic components from excessive current flow.
• Eliminates Fuse Replacement: Resettable functionality eliminates the need to replace traditional fuses.
• Increased Reliability: Solid-state construction provides reliable performance.
• Reduced Downtime: Automatic reset minimizes downtime associated with fuse replacement.

Additional Details:

The MF-MSMF110L-2 has a hold current of 1.1A and a trip current of 2.2A. The maximum voltage rating is 16V. The device is available in a 1206 package size. The operating temperature range is -40°C to +85°C. It is RoHS compliant, meaning it meets environmental regulations. The device's resistance increases significantly when the trip current is exceeded, limiting the fault current to a safe level.
