The microSMD150F is a Polymeric Positive Temperature Coefficient (PPTC) resettable fuse from TE Connectivity (formerly Tyco Electronics). It's designed to protect electronic circuits from overcurrent conditions. Unlike traditional fuses that need to be replaced after tripping, a PPTC fuse resets itself once the overcurrent condition is removed and the device cools down.

Applications

• USB ports protection
• Portable electronic devices protection
• Computer peripherals protection
• General electronic equipment protection
• Battery packs protection

Features

• Resettable overcurrent protection
• Surface mount package
• Fast trip time
• Low resistance
• Compact size
• RoHS compliant

Benefits

• Reliable Protection: Provides reliable overcurrent protection, preventing damage to sensitive electronic components.
• Resettable Functionality: Eliminates the need to replace fuses after an overcurrent event, saving time and maintenance costs.
• Compact Design: The small size allows for use in space-constrained applications.
• Fast Trip Time: Quickly interrupts the current flow during an overcurrent event, minimizing the risk of damage.
• Low Resistance: Minimizes power losses during normal operation.
• Cost-Effective: Offers a cost-effective solution for overcurrent protection compared to traditional fuses.

Additional Details

The microSMD150F has a hold current (IHOLD) of 1.5A and a trip current (ITRIP) of 3.0A. The maximum voltage rating is typically 16V. The device is packaged in a small surface mount package. Detailed electrical characteristics, trip time curves, and soldering recommendations can be found in the device datasheet. It's important to select the appropriate PPTC fuse based on the specific application requirements and operating conditions.
