The RF1180-000 is a resettable fuse (PPTC) manufactured by Littelfuse Inc. It's designed to protect electronic circuits from overcurrent conditions. These devices, also known as polymeric positive temperature coefficient (PPTC) devices, increase in resistance dramatically when a fault current occurs, effectively limiting the current and protecting downstream components. Once the fault is cleared and power is removed, the device cools down and resets to its low-resistance state.

Applications:

• USB port protection
• HDMI port protection
• Power supply protection
• Speaker protection
• General electronic circuit protection

Features:

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

Benefits:

• Provides reliable overcurrent protection
• Resets automatically after fault removal, reducing downtime
• Reduces warranty and service costs
• Helps meet regulatory requirements
• Enhances product safety and reliability

Additional Details:

The RF1180-000 has a hold current (Ih) of 1.1A and a trip current (It) of 2.2A. The maximum voltage rating is 16V. The device has a typical resistance of 0.05 Ohms. The operating temperature range is -40°C to +85°C. PPTC resettable fuses are typically used in applications where it is desirable to have a self-resetting protection device. Unlike traditional fuses, PPTCs do not need to be replaced after an overcurrent event. They are particularly useful in protecting sensitive electronic components from damage due to transient overcurrent conditions. The RF1180-000 is commonly used in consumer electronics, computer peripherals, and industrial equipment.
