The SMDC110-2 is a PolySwitch resettable fuse manufactured by Tyco Electronics (now TE Connectivity). These devices are also known as polymeric positive temperature coefficient (PPTC) resettable fuses. They are designed to protect electronic circuits from overcurrent conditions. Unlike traditional fuses, PolySwitch devices can reset themselves after the overcurrent condition is removed, making them ideal for applications where serviceability is important.

Applications

• USB Ports: Protecting USB ports from overcurrent conditions caused by faulty devices.
• Power Supplies: Preventing damage to power supplies due to short circuits or overloads.
• Battery Packs: Protecting battery packs from overcurrent conditions during charging or discharging.
• Motor Protection: Protecting small motors from overcurrent conditions.
• Consumer Electronics: Protecting various electronic devices from damage due to overcurrent.

Features

• Resettable Protection: Automatically resets after the overcurrent condition is removed.
• Solid State Design: No moving parts, providing reliable performance.
• Fast Trip Time: Responds quickly to overcurrent conditions.
• Low Resistance: Minimizes voltage drop across the device during normal operation.
• Small Size: Available in a compact package for space-constrained applications.
• Surface Mount Technology (SMT): Designed for automated assembly.

Benefits

• Improved Reliability: Prevents damage to electronic circuits due to overcurrent conditions.
• Reduced Downtime: Automatically resets after an overcurrent event, minimizing downtime.
• Simplified Design: Easy to integrate into electronic circuits.
• Cost Savings: Eliminates the need to replace fuses after an overcurrent event.
• Enhanced Safety: Protects against fire hazards caused by overcurrent conditions.
