Introduction to Fuses

A fuse is a protection device for electrical circuits that “senses” an abnormal surge of current and interrupts the circuit to prevent further damage from occurring. The interrupting time is very short, on the order of a few milliseconds or less, so that the fuse does not disrupt normal operations. Fuses are widely used in many industrial, commercial, and consumer applications, such as automobiles, appliances, and electronic devices. They are also available in a range of sizes, ranging from very small to very large.

The 39114000000 is a fast-acting miniature electronic fuse from Littelfuse. This specific fuse is ideal for overcurrent protection in high-density circuit boards. It is an expandable fuse, so it can be mounted directly on the circuit board, eliminating the need for an external fuse holder. The 39114000000 is a fully compliant IEC 60269-6/UL 248-14 sub-miniature cartridge fuse.

Working Principle of the 39114000000 Fuse

The 39114000000 fuse is a fast-acting fuse, which means that it will react quickly to current overloads. It contains a stainless steel capsule that houses a quartz capsule and an arcing material. It is sealed with a polycarbonate case. When the current through the fuse reaches a certain level, it will cause a rapid breakdown of the quartz, creating heat energy which will then be transferred to the arcing material.

The arcing material, in turn, will rapidly conduct the current to the fuse metal, creating an arc. This arc will heat up the fuse and its surrounding area to a very high temperature. This high heat will cause the polycarbonate case to melt, which will cause the fuse to open and interrupt the circuit. Since the fuse does not use a physical switch, it is considered to be a “low-resistance” device.

The 39114000000 has a wide operating temperature range of -55°C to 125°C and has a 1000V DC maximum voltage rating. Its current rating ranges from 0.05A to 15A. It is UL recognized, CE certified, and RoHS compliant. It is also available in many sizes and colors with a variety of mounts and markings.

Applications of the 39114000000 Fuse

The 39114000000 fuse can be used to protect circuitry in a variety of applications, including consumer electronics, telecommunications, automotive, industrial, and medical equipment. It is ideal for use in high-density circuit board designs, where its small size and fast-acting characteristics make it particularly useful. The 39114000000 is especially suitable for applications with sensitive electronic components that require reliable overcurrent protection.

It can also be used in equipment such as power supplies, LED lighting, pipe organs, sound systems, security systems, and other applications where the ability to quickly react to an overload is essential. Its low heat time makes it an ideal choice for applications where quick electrical response times are essential.
