Introduction

Fuses are used in electrical systems for over current protection. Overcurrent protection devices are safety components designed to protect circuits and components from excessive or damaging electrical currents. Overcurrent protective devices, such as fuses, protect circuits from damage due to overloading, short-circuits, or other fault conditions. The SF-0603SP160-2 is a surface-mountable fuse that is typically used in medium voltage electrical systems. It is a small form factor fuse that is designed to provide reliable overcurrent protection and meet industry standards. The SF-0603SP160-2 has a trip current rating of 160A and is UL Recognized and listed for branch circuit protection.

Application Field

The SF-0603SP160-2 is suitable for a wide range of applications. It is a surface-mountable fuse and is commonly used in medium-voltage electrical systems, such as power supplies, inverters, and rectifiers. It is also suitable for a range of other applications, including solar photovoltaic and wind turbine systems, as well as in automotive, marine, and communications systems. In addition to its use in medium voltage systems, the SF-0603SP160-2 can also be used as a primary or secondary protection device in low voltage systems, such as circuit boards, computer systems, and automated equipment. The device can also be used in non-electrical applications, such as aviation and aerospace systems, where overcurrent protection is used to help ensure operational safety.

Working Principle

The SF-0603SP160-2 works by either melting or rupturing when more current passes through the fuse than it is rated for. This de-energizes the circuit, preventing the flow of excessive current. The fuse has two distinct parts; a conductive bridge element, commonly referred to as a fuse link, and the body containing the fuse link. When the current passes through the fuse, the fuse link is heated and expands. If the current passing through the fuse is large enough, the bridge element will deform and relax; this deformation prevents the current from passing through the bridge element, thus de-energizing the circuit. The body of the SF-0603SP160-2 houses the fuse link, as well as a melamine-glass-filled core, an outer shield of metal, and an internal shield. The core provides thermal insulation and helps to prevent damage to the fuse body, while the shields protect the core from mechanical stress.

Conclusion

The SF-0603SP160-2 is a high-quality and cost-effective fuse suitable for a wide range of applications. It is a surface-mountable fuse designed to provide reliable overcurrent protection and meet industry standards. It can be used in medium voltage systems, such as power supplies, inverters, and rectifiers, as well as for primary or secondary protection in low voltage systems. The SF-0603SP160-2 works by either melting or rupturing when more current passes through the fuse than it is rated for, de-energizing the circuit and preventing the flow of excessive current.
