Jumpers and resistors with "zero" resistance. Reference data
Encyclopedia of radio electronics and electrical engineering / Reference materials
Comments on the article
Many companies produce special Jumper Wire wires with normalized resistance and diameter (0.6 mm, 0.8 mm) and resistors with "zero" resistance as fuse links or jumpers.
Resistors are available in a standard cylindrical package with pigtails (Zero-Ohm) or in a standard package for surface mounting (Jumper Chip).
The actual resistance values of such resistors lie in the range of units or tens of milliohms (~ 0.005 ... 0.05 Ohm). In cylindrical housings, the marking is carried out with a black ring in the middle, in surface-mounted housings (0603, 0805, 1206 ...) there is usually no marking or the code "000" (possibly "0") is applied.

A New Way to Control and Manipulate Optical Signals
05.05.2024
The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>
Primium Seneca keyboard
05.05.2024
Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>
The world's tallest astronomical observatory opened
04.05.2024
Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>
| Random news from the Archive Airless tires of the future from Michelin
25.06.2017
The French company Michelin has introduced a new concept of new generation airless tires. They will change the pattern, adjusting to road conditions.
Vision tires will be made using fully biodegradable materials such as bamboo, paper, wood, cardboard, orange peels and natural rubber.
Airless tires Vision will be printed on 3D printers - this will allow designers to control the required amount of rubber and the pattern on the tire, thus extending its service life. The tire is expected to have a lifespan of around 10-15 years before it can be recycled.
The Vision's airless tire cannot burst or fly out. In addition, it is designed in such a way that the rigid material in the center of the tire becomes softer and more flexible as it approaches the outer radius.
Manufacturers also plan to build special sensors into tires that will remind the driver that it is time to change the pattern. And of course, you can track all the necessary information using the application on your mobile phone. The car owner will also be able to change the pattern using 3D printing technology.
