APPLICATIONS · Test and measuring equipment · Medical equipment · Industrial equipment. The resistors are tested in accordance with EN 140 401-801 (superseding CECC 40 401-801) which refers to EN 60115-1 and EN140 400. Approval of conformity is indicated by the CECC logo on the package label. DESCRIPTION MCT 0603, MCT 0805 and MCA 1206 Precision Thin Film Flat Chip Resistors combine the proven reliability of the professional products with an advanced level of precision and stability. Therefore they are perfectly suited for applications in the fields of test and measuring equipment together with industrial and medical electronics. BCcomponents BEYSCHLAG has achieved "Approval of Manufacturer" in accordance with EN 100 114-1. The release certificate for "Technology Approval Schedule" in accordance with CECC 240 001 based on EN 100 114-6 is granted for the BCcomponents BEYSCHLAG manufacturing process. Production is strictly controlled and follows an extensive set of instructions established for reproducibility. A homogeneous film of metal alloy is deposited on a super high grade (96% Al203) ceramic substrate and conditioned to achieve the desired temperature coefficient. Specially designed inner contacts are deposited on both sides. A special laser is used to achieve the target value by smoothly fine trimming the resistive layer without damaging the ceramics. A further conditioning is applied in order to stabilize the trimming result. The resistor elements are covered by a blue protective coating designed for electrical, mechanical and climatic protection. The terminations receive a final pure tin on nickel plating. 2002 Dec 19 On request, resistors are available with established reliability in accordance with CECC 40 401-801 Version E. Please refer to the special data sheet for information on failure rate level, available resistance ranges and order codes. 2 BCcomponents Product specification MCT 0603; MCU 0805; MCA 1206 Precision flat chip resistors QUICK REFERENCE DATA DESCRIPTION Metric size Resistance range MCT 0603 MCU 0805 MCA 1206 RR 1608M RR 2012M RR 3216M 47 W to 150 kW 47 W to 332 kW 47 W to 332 kW ±0,25%; ±0,1% ±0,1% ±25 ppm/K; ±15 ppm/K; ±10 ppm/K ±25 ppm/K Resistance tolerance Temperature coefficient Operation mode precision standard precision standard precision standard Climatic category (LCT/UCT/days) 10/85/56 55/125/56 10/85/56 55/125/56 10/85/56 55/125/56 Rated dissipation, P70 0,032 W 0,1 W 0,050 W 0,125 W 0,1 W 0,25 W Operating voltage, Umax AC/DC 25 V 75 V 35 V 150 V 50 V 200 V Film temperature 85 °C 125 °C 85 °C 125 °C 85 °C 125 °C Max. resistance change at P70 for resistance range, DR/R max., after: 47 W to 150 kW 47 W to 332 kW 47 W to 332 kW 1 000 h £ 0,1% £ 0,2% £ 0,1% £ 0,2% £ 0,05% £ 0,1% 8 000 h £ 0,2% £ 0,4% £ 0,2% £ 0,4% £ 0,1% £0,25% 225 000 h £ 0,5% £ 1,0% £ 0,5% £ 1,0% £ 0,25% £ 0,5% Specified lifetime 225 000 h 225 000 h 225 000 h 100 V 200 V 300 V Insulation voltage : 1 minute; Uins continuous Failure rate 2002 Dec 19 75 V 75 V 75 V £ 2 ´ 10-9/h £ 2 ´ 10-9/h £ 2 ´ 10-9/h 3 BCcomponents Product specification MCT 0603; MCU 0805; MCA 1206 Precision flat chip resistors Table 1 Temperature coefficient and resistance range RESISTANCE VALUE(1) DESCRIPTION T.C.
