The MF-NSMF010-2 is a resettable fuse, also known as a polymeric positive temperature coefficient (PPTC) device, manufactured by Bourns. It is designed to protect electronic circuits from overcurrent conditions. When an overcurrent event occurs, the device heats up and increases its resistance, limiting the current flow and protecting the circuit. Once the fault is removed, the device cools down and returns to its low-resistance state, allowing normal operation to resume.

Applications:

• USB port protection
• HDMI port protection
• Power supply protection
• General electronic equipment protection
• Battery protection

Features:

• Resettable overcurrent protection, eliminating the need for fuse replacement
• Surface-mount package (SMD), allowing for automated assembly
• Compact size, saving board space
• Fast trip time, quickly interrupting overcurrent events
• Low resistance, minimizing voltage drop during normal operation

Benefits:

• Reduced maintenance costs due to resettable functionality.
• Simplified manufacturing process due to surface-mount design.
• Increased design flexibility due to small size.
• Improved circuit protection due to fast response time.
• Minimal impact on circuit performance during normal operation due to low resistance.

Additional Details:

The MF-NSMF010-2 has a hold current of 0.1A and a trip current of 0.2A. The maximum voltage rating is 30V. The operating temperature range is -40°C to +85°C. The device is packaged in a 1206 surface-mount package. It provides a reliable and convenient solution for overcurrent protection in a wide range of electronic devices. It is commonly used to protect sensitive electronic components from damage due to short circuits or excessive current draw.
