resistors CN-RT anti sulfuration chip networks (concave termination) EU features • Excellent anti-sulfuration characteristic due to using high sulfuration-proof inner top electrode material • More advancement in the mounting density than individual chip resistors • Mounting cost reduction by decreasing the number of parts mounting times • Higher self-alignment effect in reflow-soldering process • Suitable for an image recognition mounter due to square corner design • Products with lead-free terminations meet EU RoHS requirements. EU RoHS regulation is not intended for Pb-glass contained in electrode, resistor element and glass. dimensions and construction b L P a C W d Inner Ceramic Protective Outer Resistive Electrode Film Substrate Coating Electrode ordering information New Part # CN 1J Type Size CN CNZ 1J 2A 2B Dimensions inches (mm) L±0.2 W±0.2 c d±0.1 t±0.1 a (top) a (bottom) b±0.1 .02±.004 .016±.006 CN1J4RT 0.126 0.06 .01±.008 0.016 (0.5±0.1) (0.4±0.15) (1.6) (0.3±0.2) (0.4) (0603x4) (3.2) Type CN2A4RT (0805x4) 0.2 CN2B4RT (5.08) (1206x4) 4 Number of Resistors 4 0.08 .016±.008 (2.0) (0.4±0.2) 0.022 0.126 .02±.01 (0.55) (3.2) (0.5±0.3) RT Termination Material RT : Sn 0.006 0.024 (0.6) .03±.004 .03±.006 (0.15) (0.8±0.1) (0.75±0.15) TD Packaging TD: Paper TE: Plastic Embossed 103 Nominal Resistance 3 digits Weight (g) P 0.031 (0.8) 10.2 20.6 0.05 (1.27) 33.5 J Tolerance J : ±5% For further information on packaging, please refer to Appendix A.
