MARKET SEGMENTS AND APPLICATIONS Market Segment Industrial Telecom Consumer Sound & Vision DAP Lighting Aumotive Application Power supplies Mor speed controls Line protection resisr Power supplies Audio Edirs Systems High end hi-fi Kitchen appliances White good Ballast equipment Dashboard electronics Electronic fuel injection TECHNOLOGY The resisr element is a resistive wire which is wound in a single layer on a ceramic rod. Metal caps are pressed over the ends of the rod. The ends of the resistance wire and the tinned copper leads or copper-clad iron leads are connected the caps by welding. The resisr is coated with a green silicon cement which is non-flammable, will not drip even at high overloads and is resistant most commonly used cleaning solvents, in accordance with MIL-STD-202, method 215 and IEC 60068-2-45. The standard resisr is supplier with axial lead taped in a box or with formed leads as a special type. page 1 of 11
