Introduction

12OHFMA71 is a series of specialty fuses manufactured by Schurter as part of their Electronic Protection products. This type of fuse is typically used in the protection of electronic circuits from excessive electrical currents like those produced by surges, short circuits, and other over currents. It is designed for use in applications such as solar cell protection, LED lighting, automotive, avionics, industrial automation, railway protection, home appliances, and office equipment.

Construction

The 12OHFMA71 fuse is composed of a fuse element, a series of pins, and a housing. The element is made of a copper ribbon with a piece of polyimide as a dielectric material. The pins are made of stainless steel for high-temperature applications and are connected to the fuse element with Flat-Tip rivets. The housing is made of Polyester with thermoplastic insulation material for fire safety. Additionally, the fuse is available in different sizes and current ratings to suit the application’s requirements.

Operation

The 12OHFMA71 fuse works on the principle of temperature rise. The fuse element is designed to heat up to a predetermined temperature when there is an over current in the system. As the temperature of the element rises, the fuse element will melt, breaking the circuit and shutting down the system. The fuse element is designed to melt at a safe temperature so that the system does not get damaged by the excessive current.

Applications

The 12OHFMA71 specialty fuses are used in a variety of applications due to their high temperature capabilities, high surge protection, and fast response times. They are commonly used in electric vehicles, solar panel systems, LED lamps, and industrial automation. Additionally, they are used in office equipment, home appliances, avionics, and railway protection systems.

Advantages

The 12OHFMA71 specialty fuses offer several advantages over standard fuses that include:

• High temperature capabilities
• High surge protection
• Fast response times
• Small size
• High reliability
• Cost effective

Conclusion

The 12OHFMA71 specialty fuses are a reliable and cost-effective solution for protecting electronic circuits from over current and short circuits. They offer high temperature capabilities, high surge protection, and fast response times, making them a great choice for a variety of applications in electric vehicles, solar panel systems, LED lamps, and industrial automation. Additionally, their small size means they can be used in applications where traditional fuses may not fit.
