What Is a Shunt (Resistor)? How Current Sensing Works and How to Choose17 July 2026
A shunt is a measuring element that uses voltage to indicate current. It is made according to the principle of generating voltage at both ends of the resistor when DC current passes through the resistor. It is connected in parallel with the current circuit of measuring instruments to expand its measurement range; or An element on which voltage is measured, thereby indirectly measuring current.
What is An Optoisolator?09 January 2021
An optoisolator, also called optical coupler, optocoupler, and opto-isolator, is a device that encapsulates the infrared light-emitting device, the infrared light receiving device, and the signal processing circuit in the same tube socket.

Japan's Three-Stage Strategy to Revive the Semiconductor Industry01 April 2022
Continuing chip shortages and the high risk of disruptions in the semiconductor supply chain remain major challenges for governments around the world, and Japan is under tremendous pressure to find solutions to revitalize the semiconductor industry. In recent years, the global market share of Japanese semiconductor companies has been declining, from 50.3% in 1988 to less than 10%. To develop an effective industry revitalization strategy, the Japanese government and domestic semiconductor companies are now reflecting on why Japan's semiconductor industry has been losing ground to foreign competitors in the global market.
