Accurate current sensing for better power efficiency There is a global push to ensure electronic circuits to become more efficient so as to cumulatively reduce carbon emissions.  Circuit designers and system operators need to understand the level of current through the circuit and that being delivered to the attached loads so as to maximize the efficiency of the power source and attached loads. To achieve this,  current sensing resistors  are used. They are not only cost-effective but also possess high measurement accuracy. Current sensing resistors can be used in applications in all market segments, for instance, the automotive, computer technologies and industrial segments. How current sense resistors work Current sense resistors detect current by converting current to voltage. Since the resistance of the resistor (R) is known, the voltage (V) across the resistor can be measured and the current flow determined using Ohm’s law. V = IR It sounds simple, rig...

Taking over hybrid circuits Multilayer Ceramic Chip Capacitors (MLCCs) compose up to 30% of the total components found in a typical hybrid circuit. MLLC’s are made up of the monolithic ceramic block that has comb-like sintered electrodes. The electrodes come to the surface at the face ends of the monolithic ceramic block where they make an electrical contact using metallic layers. Structure and manufacture of Multilayer Ceramic Capacitors Structure The basic structure of capacitors features a pair of electrodes separated by a dielectric. In  multilayer ceramic capacitors  the same structure is repeated level after level hence increasing the amount of charge stored. Manufacture When making the dielectric materials, they are mixed with various solvents among other substances and pulverized so as to form a slurry-type paste. The paste is then drawn into thin sheets and then made into rolls. They are then coated with metal paste which will act as internal ele...
