2920L050DR

The 2920L050DR is a component manufactured by Littelfuse Inc., known for its expertise in circuit protection and electronic components. This specific part is a Polymeric Positive Temperature Coefficient (PPTC) resettable fuse, designed to provide overcurrent protection in various electronic applications.

Key Features:

1. Type: The 2920L050DR is a resettable fuse, which means it can automatically reset itself after the fault condition is removed, eliminating the need for replacement.

2. Current Rating: It has a hold current rating of 5A, which indicates the maximum continuous current the device can handle without tripping under normal operating conditions.

3. Trip Current: The trip current is typically higher than the hold current, allowing for brief surges without activating the fuse. This characteristic is crucial for applications where inrush currents may occur.

4. Voltage Rating: The device is rated for a maximum voltage of 60V, making it suitable for a variety of low-voltage applications.

5. Temperature Range: The operating temperature range is typically from -40°C to +85°C, allowing it to function effectively in diverse environmental conditions.

6. Package Type: The 2920L050DR is housed in a compact surface-mount package, which facilitates easy integration into printed circuit boards (PCBs) and helps save space in electronic designs.

7. Material: The fuse is made from a polymeric material that exhibits a positive temperature coefficient, meaning its resistance increases with temperature. This property is what allows the device to trip and protect the circuit when excessive current flows through it.

8. Applications: This resettable fuse is commonly used in consumer electronics, telecommunications, automotive applications, and industrial equipment, where overcurrent protection is essential to prevent damage to sensitive components.

9. Compliance: The 2920L050DR typically meets various industry standards for safety and reliability, ensuring it can be used in critical applications.

Summary:

The Littelfuse 2920L050DR is a reliable and efficient solution for overcurrent protection in electronic circuits. Its resettable nature, combined with its compact size and robust performance characteristics, makes it an ideal choice for designers looking to enhance the safety and longevity of their electronic devices.
