resistors CN-KRT anti sulfuration chip networks (convex 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 •Easy soldering fillet inspection •Suitable for an image recognition mounter due to square corner design •Marking: Black body color •Products with lead-free termination meet EU RoHS requirements. EU RoHS regulation is not intended for Pb-glass contained in electrode, resistor element and glass. dimensions and construction a2 a L p Type b W C t Protective Outer Coating Electrode Resistive Film Ceramic Substrate NEW d Inner Electrode CN1E2KRT (0402x2) CN1E4KRT (0402x4) CN1F8KRT (0602x8) Dimensions inches (mm) d t a a2 b P* — .007±.002 (0.17±0.05) .026 (0.67) .079±.004 .039±.004 .006±.004 .010±.008 .014±.004 .012±.006 .016±.006 .006±.004 (2.0±0.1) (1.0±0.1) (0.15±0.1) (0.25±0.2) (0.35±0.1) (0.3±0.15) (0.4±0.15) (0.15±0.1) .020 (0.5) L W c .039±.004 .039±.004 .006±.004 .010±.004 .014±.004 .013±.004 (1.0±0.1) (1.0±0.1) (0.15±0.1) (0.25±0.1) (0.35±0.1) (0.33±0.1) .150±.004 .063±.004 .012±.004 .012±.004 .018±.004 .012±.004 (3.8±0.1) (1.6±0.1) (0.3±0.1) (0.3±0.1) (0.45±0.1) (0.3±0.1) — .006* (0.15) .020 (0.5) * Referential values. ordering information CN 1E 4 K RT TD 103 J Type Size Number of Resistors Terminal Convex Termination Material Packaging Nominal Resistance Tolerance 2 4 8 K: Convex type with squared corners RT: Sn 3 digits J: ±5% 1E NEW 1F TD: Paper applications and ratings Power Resistance Part Rating per Range Desigation Element J: ±5 E24 CN1E2KRT CN1E4KRT CN1F8KRT 0.063 0.063* 3~1M 10~1M T.C.R.
