0453.375MR - Fuse 3.75A

Littelfuse Nano² 3.75A 125V SMD Fuse — Part No. 0453.375MR

The Littelfuse Nano²® 453 series 0453.375MR SMD fuse is an electronic protection component designed for printed circuit boards. It protects equipment against overloads and short circuits by interrupting the current very rapidly.

This fuse is of the very fast acting (FF) type, which enables an immediate response in the event of an electrical fault, thereby protecting sensitive components such as circuit boards, power supplies and embedded systems.

Thanks to its SMD (surface mount) format, it is mounted directly onto the printed circuit board, offering space savings and easy integration into industrial or consumer electronic equipment.

• IT and network equipment
• Embedded systems and sensitive electronics

Function

• Protects circuits against overcurrent
• Cuts off the power in the event of a short circuit
• Preserves sensitive electronic components
• Ensures overall system safety

Possible symptoms in the event of a fault

• Electronic board completely powered down
