Fuses

A fuse (from the Latin word fusus meaning "melted") is a device used as a component or device for protection within a circuit. While current flows freely through it, it interrupts the circuit in the event of a fault, preventing a short circuit or overload. It works on the principle of overload protection and is designed to protect the electrical circuit or device from damage or destruction by limiting the current to a specific and safe level. Fuses have four general design parameters, including size, voltage and amperage rating, brand compatibility and mounting configuration.

0313003.H

The 0313003.H is a mini-fuse which features a miniature size and voltage of 32 V DC and a current rating of 3-amp. This mini-fuse is designed to protect sensitive circuits from overloads and short-circuiting due to over-current and over-heating. It is commonly used in computer systems, power supplies, automotive applications, LED lighting, industrial protection circuits, and other applications.

Application Field

The 0313003.H mini-fuse is suitable for providing primary low current over-current and overheat protection in applications where space is a limiting factor, such as mobile phones, PDAs, printers, laptops, business computers, and portable electronic devices. It is also widely used for automotive applications, LED lighting and industrial protection circuits.

Working Principle

The 0313003.H mini-fuse works on the principles of overload protection. It is designed with a metal element that is quickly heated and melted when the current through it exceeds its rated value. When the current passing through the fuse is higher than its rated current, the fuse will quickly heat up and separate the circuit, thus avoiding a short circuit or overload.

The mini-fuse is constructed with a metal strip that is filled with a special alloy. When an overload of current flows through the fuse, the alloy heats up and melts the metal strip, thus breaking the circuit. After heat has been produced, the mini-fuse can no longer be used and needs to be replaced.

Advantages

• Low size and low profile
• Low voltage and high current rating
• Good compatibility with other brands of fuses
• Easy mounting
• High level of protection for electrical circuits
• Meets the low voltage directive

Disadvantages

• Any over-current will cause the element to melt, rendering the fuse unusable
• Time current curve is not linear
• High cost

The 0313003.H mini-fuse is an effective and reliable fuse for providing protection to sensitive electrical circuits, whether in the automotive, industrial or electronics fields. It is capable of providing fast, accurate protection against short-circuits and overloads, while also taking up minimal space. With its wide variety of advantages and disadvantages, it is important to carefully consider its use before using the mini-fuses for any application.
