On the marking of ceramic capacitors. Encyclopedia of radio electronics and electrical engineering

Comments on the article
Recently, Asian-made ceramic capacitors with a capacity from 1 pF to 40 thousand pF with a negative TKE have appeared on the Russian market. Many radio amateurs have difficulty deciphering their markings. The measurements I made showed that on capacitors with a capacity of up to 99 pF, the number of picofarads is indicated.
The designation of capacitors with a capacity of more than 100 pF consists of three digits: the first two indicate the value of the first factor, and the third - the degree of the second factor, equal to 10. For example, the number "403" stands for 40 103 \u40d 101 thousand pF, and the number "10" as 101 100 = 2 pF. The capacitance of capacitors of more than 0,002 thousand pF is sometimes indicated in microfarads. For example, 2 \uXNUMXd XNUMX thousand pF.

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 Video recorder for mobile phones
18.06.2004
Mitsubishi Corporation Division Mitsubishi Plastics has released the Pyramid video recorder, designed to record television programs on SD or miniSD memory cards for playback on mobile phones or PDAs.
The dimensions of the Pyrami recorder are 115x115x70 mm, it supports SD and miniSD memory cards. The recorder connects to a TV or VCR with a cable and can record up to two hours of video on a 128 Mbit memory card.
Ten models of mobile phones with support for video viewing and SD and miniSD memory cards are currently available in the Japanese market, eight are offered by NTT DoCoMo (N900i, F900i, SH900i, P900i, P2102V, F2102V, N505iS and F505i) and two models by Vodafone (J-SH53 and V601SH). The cost of the Pyramid recorder is 20000 yen (approximately $185).
