BCcomponents DATA SHEET DCS 0402; DCT 0603; DCU 0805; DCA 1206 Thick film flat chip resistors Product specification Supersedes data of 13th May 2002 File under BCcomponents, BC08 2002 Sep 24 BCcomponents Product specification Thick film flat chip resistors FEATURES ceramic substrate to form the resistive layer. Pre-contacts are printed on both sides of the substrate. The resistors are laser trimmed to the target value. The resistor elements are covered by glass and a protective coating combined for superior electrical, mechanical and climatic protection. The prepared terminations receive an electroplating of PbSn solder on nickel plating. A three or four digit code designates the nominal resistance value. * State of the art thick film technology * Improved termination design * Standard TC: 100 and 200 ppm/K * Tight tolerance available: 1% Case sizes Imperial: 0402 Metric: 0603 0805 1206 The result of the determined production is verified by a final test performed on 100% of the individual chip resistors. Only accepted products are laid directly into the paper tape according to IEC 60286-3. RR 1005M RR 1608M RR 2012M RR 3216M APPLICATIONS The resistors are suitable for processing on automatic SMD assembly systems. They are suitable for automatic soldering using wave, reflow or vapour phase. The encapsulation is resistant to all cleaning solvents commonly used in the electronics industry, including alcohols, esters and aqueous solutions. * All general purpose applications * Office automation equipment * Consumer electronics. DESCRIPTION The resistors are tested in accordance with IEC 60115-1 and IEC 60115-8. DCS 0402, DCT 0603, DCU 0805 and DCA 1206 thick film chip resistors are made for all general purpose applications. They are typically used in the production of office automation equipment and consumer electronics. This product family of thick film flat chip resistors is completed by Zero Ohm Jumpers.
