Reading time: 4 minute Transistors have a very long life, they can work with lower voltage sources for greater safety. In this article we present a number of transistor manufacturers, which have the best price-quality offers.
Reading time: 2 minute This catalog of fixed resistors appeared in 2014 and contains the following: Surface Mount Resistors (Rectangular, Chip Resistor Array, Chip Attenuator, Power Type, Common specifications), Power Type Resistors and Fusing Resistors.
Reading time: 3 minute Dr. Phys. Eugen Pavel, from the Institute of Atomic Physics in Magurele, made a CD (Compact Disk), made of glass, with a storage capacity 15000 times higher compared to an ordinary one. In November 1999, his invention was awarded the gold medal at the "Brussels Europa" World Invention Fair. In the same year, the author wanted at any cost the serial production of this CD in Romania.
Reading time: 8 minute The article presents the top 10 types of resistors that offer high reliability and stability or high temperature performance for a wide range of applications. These resistors are designed for harsh environments, including automotive and industrial applications.
Reading time: 2 minute A supercapacitor is also known as a two-layer ultracapacitor or electrolytic capacitor. Supercapacitors consist of two electrodes, an electrolyte, a separating membrane, and their performance differs depending on the characteristics of the materials used.
Reading time: 3 minute The article presents in a structure classified by quality levels, types of capacitors used in consumer power sources (PC, TV, appliances, etc.). The purpose of this article is to provide detailed information about the most important part of an electronic equipment, its power supply unit.
Reading time: 2 minute With a height of over 2 m, a weight of 1500 kg and an impressive design, it looks more like a futuristic teleportation device than a power amplifier. Its beauty is matched only by specifications. In the construction of this applicator, some more special materials were used, such as: aeronautical quality aluminum and gold.
Reading time: 5 minute The most critical security issues for IoT environments are those regarding the protection of the privacy of data generated by interconnected devices and transmitted over IP networks. Therefore, security solutions must address these issues as a matter of priority.
Reading time: 3 minute A proficient and visionary inventor, the creator of the flying backpack, an idea taken over by NASA for the intercapsular movements of cosmonauts, and of the car that consumes 0,5 liters per kilometer, Justin Capra tried to break down barriers and mentalities.
Reading time: 3 minute During World War II, Bletchley Park was the headquarters of the UK's leading cryptanalysis organization. The codes and figures of several Axis states were deciphered here, the most important being the German Enigma and Lorenz cars, owned by the Government Code and Cypher School (GC&CS), which regularly entered the Axis Powers' secret communications.
