The MINISMD110-2 is a surface mount resettable fuse, also known as a polymeric positive temperature coefficient (PPTC) device, manufactured by TE Connectivity. This device is designed to protect electronic circuits from overcurrent and short circuit conditions. When an overcurrent event occurs, the device heats up and its resistance increases dramatically, limiting the current flow and protecting the circuit. Once the fault is cleared and power is removed, the device cools down and its resistance returns to its normal low level, allowing the circuit to resume operation.

Applications:

• USB Ports: Protects USB ports and connected devices from overcurrent conditions.
• Portable Electronics: Used in smartphones, tablets, and other portable devices to protect against short circuits and overloads.
• Battery Packs: Protects lithium-ion and other battery packs from overcurrent and short circuit failures.
• Power Supplies: Provides overcurrent protection for power supplies and adapters.
• Automotive Electronics: Used in automotive electronic systems to protect against electrical faults.

Features:

• Resettable Overcurrent Protection: Automatically resets after the overcurrent condition is removed.
• Surface Mount Package: Allows for easy automated assembly on printed circuit boards.
• Compact Size: Saves valuable board space in space-constrained applications.
• Low Resistance: Minimizes voltage drop across the device during normal operation.
• Fast Trip Time: Quickly responds to overcurrent events to protect the circuit.

Benefits:

• Improved System Reliability: Prevents damage to electronic circuits caused by overcurrent conditions.
• Reduced Warranty Costs: Minimizes the risk of product failures due to electrical faults.
• Simplified Circuit Design: Eliminates the need for manual fuse replacement.
• Increased Safety: Protects users from electrical hazards caused by short circuits.
• Cost-Effective Protection: Provides a reliable and cost-effective overcurrent protection solution.

The MINISMD110-2 is available in a standard surface mount package and is compatible with automated assembly equipment. The device is RoHS compliant and lead-free, meeting environmental regulations. Its compact size and low resistance make it an ideal choice for a wide range of electronic applications requiring overcurrent protection. The specific trip current and hold current characteristics of the device are detailed in the product datasheet, allowing designers to select the appropriate device for their application.
