Resettable fuses - PolySwitch devices. A resettable fuse or polymeric positive temperature coefficient device (PPTC) is a passive electronic component used to protect against overcurrent faults in electronic circuits. The device is also known as a multifuse or polyfuse or polyswitch. They are similar in function to PTC thermistors in certain ...
Fuse (electrical) A miniature time-delay 250 V fuse that will interrupt a 0.3 A current at after 100 s, or a 15 A current in 0.1 s. 32 mm (1 1/4") long. In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal ...
IEC 60269 unifies the electrical characteristics of fuses that are dimensionally interchangeable with fuses built to earlier British, German, French or Italian standards. [2] The standard identifies application categories which classify the time-current characteristic of each type of fuse. The application category is a two-digit code.
An antifuse is an electrical device that performs the opposite function to a fuse.Whereas a fuse starts with a low resistance and is designed to permanently break or open an electrically conductive path (typically when the current through the path exceeds a specified limit), an antifuse starts with a high resistance--an open circuit--and programming it converts it into a permanent electrically ...
Littelfuse, Inc. Littelfuse, Inc. is an American electronics manufacturing company headquartered in Chicago, Illinois. [2][3] The company primarily produces circuit protection products (fuses) but also manufactures a variety of switches, automotive sensors and, through its subsidiary Zilog, microprocessors. [3][4] Littelfuse was founded in 1927.
Window Maker is a free and open-source window manager for the X Window System, allowing graphical applications to be run on Unix-like operating-systems. It is designed to emulate NeXTSTEP's GUI as an OpenStep-compatible environment. [2] Window Maker is part of the GNU Project. [3] [4]
The Lucas 1/4" diameter glass tube fuse have a different length as compared to the standard US item. The Lucas 1/4" diameter glass tube fuse is 1 + 5 ⁄ 32 in (29 mm) long, while the US standard 1/4" glass tube fuse is 1 + 1 ⁄ 4 in (32 mm)] long. However, many Lucas fuse holders permit the longer US version to be installed easily.
BS 1363 is a British Standard which specifies the common single-phase AC power plugs and sockets that are used in the United Kingdom. Distinctive characteristics of the system are shutters on the line and neutral socket holes, and a fuse in the plug. It has been adopted in many former British overseas territories.
