JLLS150.X

Electrical

Specialty Fuses

The JLLS150.X is a range of microelectronic circuit protection components. It provides reliable overcurrent protection for circuits employing integrated circuits such as DSPs, ASICs, MLPs, and microcontrollers. It is mostly used for polyfuse and zipfuse applications. The component is a chip fuse composed of a silver-coated copper grid, which is protected by a polyolefin casing. It has a low resistance, high insulation strength, excellent resistance to vibration, and a high breakdown capacity. It also has superior temperature characteristics, with an operating temperature range of 10 to 160°C. The JLLS150.X offers a variety of features including a high cycle life, low power consumption, and a tight tolerance current rating.

The principle behind the JLLS150.X is the same as any other type of overcurrent protection: when the current flowing through the fuse exceeds its rating, the fuse wire will heat up. This causes a transition of the fuse material, typically silver, from a high resistance (conductive) to a low resistance (non-conductive). As a result, the current flow through the wire is stopped, thus protecting the circuit from any further damage.

The JLLS150.X is designed to blow quickly and reliably at a specified current level. The fuse has a temperature coefficient of -0.3%/°C, meaning that it can quickly respond to an overcurrent condition and protect the circuitry from damage due to excessive heat. The JLLS150.X is designed to operate in a wide temperature range, from -55°C to +125°C. Thus, it can be used in a variety of harsh environments, including outdoor installations, industrial, and automotive applications.

The JLLS150.X is easy to install and requires minimal space. The component has a small size, about the size of a finger nail. It also has an easy-to-assemble design, with two solder pads for connecting the leads of the component. This makes it ideal for automated assembly processes, which save both time and money.

In conclusion, the JLLS150.X is a reliable, cost-effective solution for overcurrent protection. It combines high power dissipation with excellent tolerance to temperature and vibration, offering superior protection for circuits such as DSPs, ASICs, MLPs, and microcontrollers. It is quick to respond to overcurrent conditions, easy to assemble, and requires minimal space. As such, it is ideal for a variety of applications, from outdoor installations to industrial and automotive components.
