Welwyn Components Revolutionises Pulse Performance Density When a major manufacturer of industrial circuit breakers wanted to re-engineer its core range of products, the research and development team at TT electronics Welwyn Components set to work on a revolutionary solution. One area of focus was how to provide power resistive products in an SMD assembly. For the inrush resistor slots (R1 & R2 below) the traditional choice was wirewoun
