The efficient and reliable operation of LED lighting is dependent on the right choice of current-limiting resistor. Not all resistors are the same and growth in new markets like high-power LED lighting is serving to highlight the importance of understanding all...

The subject of power supplies is potentially very broad and the application of resistors in power supplies is quite diverse. Here we will focus on power supply units (PSUs) designed for use in electronic appliances that nominally require fixed DC outputs ranging from...

Power resistors and resistance heaters share many common design considerations. In both products, good thermal design ensures low thermal resistance between the element and the exterior environment. Both must be rugged and reliable. Power resistors are often used in...

Resistance Resistance is one of three basic quantities in electrical or electronic circuits: Current is the flow of electrons through a circuit. It is the principle quantity because it does work, and accomplishes the desired results. We measure current in Amperes....

The difference between thin and thick film make this a natural choice. It is recommended to use thin film technology rather than thick film for 0.1% tolerance or better high precision products for better resistance consistency. From the perspective of product...

What is TCR? The resistance value of a resistor changes with temperature and TCR stands for Temperature Coefficient of Resistance, which indicates that when the temperature changes by 1℃, there will be a relative change of resistance value in ppm/℃. The resistance...
