The Bourns MF-MSMF110 is a resettable fuse, also known as a Polymer Positive Temperature Coefficient (PPTC) resettable fuse. This device is designed to protect electronic circuits from overcurrent conditions. Unlike traditional fuses that need to be replaced after tripping, the MF-MSMF110 resets itself once the overcurrent condition is removed, providing a convenient and cost-effective solution for circuit protection.

Applications

• USB Ports: Used to protect USB ports from overcurrent faults.
• Hard Disk Drives: Implemented in hard disk drives to protect sensitive components.
• Mobile Phones: Incorporated in mobile phones for battery and circuit protection.
• Game Consoles: Employed in game consoles to protect against electrical surges and overcurrent.
• General Electronics: Suitable for general electronic applications requiring resettable overcurrent protection.

Features

• Resettable Fuse: Automatically resets after the overcurrent condition is removed.
• Overcurrent Protection: Protects circuits from excessive current flow.
• Compact Size: Small footprint for space-constrained applications.
• Low Resistance: Minimal impact on circuit performance under normal operating conditions.
• Fast Trip Time: Quickly responds to overcurrent events to prevent damage.

Benefits

• Reduced Downtime: Eliminates the need to replace fuses, reducing downtime and maintenance costs.
• Enhanced Circuit Protection: Provides reliable overcurrent protection, preventing damage to sensitive components.
• Cost-Effective: Reduces the cost associated with replacing traditional fuses.
• Improved Reliability: Enhances the overall reliability of electronic devices.

Additional Details

The MF-MSMF110 has a hold current of 1.1A and a trip current of approximately 2.2A. It is designed to operate over a wide temperature range and is compliant with industry safety standards. The device's resistance increases significantly when it trips, limiting the current flow and protecting the circuit. Once the fault is cleared and the device cools down, its resistance returns to normal, allowing the circuit to resume operation. Refer to the Bourns datasheet for detailed specifications, including trip time curves and environmental ratings. The MF-MSMF110 provides a robust and reliable solution for overcurrent protection in a wide range of electronic applications.
