FEATURES
MCT 0603; MCU 0805; MCA 1206
The result of the determined production is verified by an extensive testing procedure and optical inspection performed on 100% of the individual chip resistors. Only accepted products are laid directly into the paper tape in accordance with EN 60 286-3. The resistors are suitable for processing on automatic SMD assembly systems and 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. The resistors are lead-free, the pure tin plating provides compatibility with lead-free soldering processes. The immunity of the plating against tin whisker growth has been proven under extensive testing. All products comply with the CEFIC-EECA-EICTA list of legal restrictions on hazardous substances. Solderability is specified for 2 years after production or re-qualification. The permitted storage time is 20 years. 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. 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. 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.

Case sizes Imperial: Metric: 0603 RR 1608M 0805 RR 2012M 1206 RR 3216M
APPLICATIONS
* Test and measuring equipment * Medical equipment * Industrial equipment.
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. 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.
