The SST750MA(T&R) is a surface mount resettable fuse (PPTC) from Bel Fuse Inc. This device is designed to protect electronic circuits from overcurrent conditions. When an overcurrent event occurs, the resistance of the PPTC increases significantly, limiting the current flow and protecting the circuit. Once the fault is cleared and power is removed, the PPTC cools down and returns to its low-resistance state, allowing the circuit to resume normal operation. The (T&R) designation indicates that the component is provided on Tape and Reel for automated assembly.

Applications:

• USB Ports: Protecting USB ports from overcurrent conditions caused by faulty devices.
• Power Supplies: Providing overcurrent protection in power supplies.
• Battery Packs: Protecting battery packs from short circuits and overloads.
• Consumer Electronics: Used in laptops, tablets, and other consumer electronics to protect against overcurrent events.
• Automotive Electronics: Providing circuit protection in automotive electronic systems.

Features:

• Resettable Fuse (PPTC): Automatically resets after the fault condition is removed.
• Surface Mount Package: Designed for surface mount assembly.
• Fast Trip Time: Quickly responds to overcurrent conditions to protect the circuit.
• Low Resistance: Offers low resistance during normal operation to minimize power loss.
• Tape and Reel Packaging: Provided on tape and reel for automated assembly.

Benefits:

• Overcurrent Protection: Protects electronic circuits from damage due to overcurrent conditions.
• Resettable: Eliminates the need to replace fuses after an overcurrent event.
• Automatic Reset: Automatically resets when the fault is cleared, reducing downtime.
• Easy Assembly: Designed for easy surface mount assembly.
• Reliable Performance: Provides reliable overcurrent protection for a wide range of applications.

Technical Specifications: The SST750MA(T&R) typically features a hold current of 0.75A, a trip current of 1.5A, and a maximum voltage rating of 30V. The typical resistance is around 0.15 Ohms. It is available in a 1206 surface mount package. These specifications should be confirmed with the official datasheet.

In conclusion, the SST750MA(T&R) from Bel Fuse Inc. is a reliable and convenient surface mount resettable fuse designed to protect electronic circuits from overcurrent conditions. Its resettable functionality, fast trip time, and low resistance make it an excellent choice for a wide range of applications, including USB ports, power supplies, and battery packs.
