flat chip resistors (anti-sulfuration) features EU • Excellent anti-sulfuration characteristic due to using high sulfuration-proof inner top electrode material • Excellent heat resistance and weather resistance are ensured by the use of metal glaze thick film • High stability and high reliability with the triple-layer structure of electrode • Marking: Z1H: Green protective coating RK73B1F ~ W3A, RK73Z1J ~ W3A: Black protective coating RK73H1F ~ W3A: Blue protective coating • 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. • AEC-Q200 Qualified: 0201 (1H), 0402 (1E), 0603 (1J), 0805 (2A), 1206 (2B), 1210 (2E), 2010 (W2H), 2512 (W3A) dimensions and construction L c c Type W Solder Plating Protective Coating d NEW Ni Plating t Resistive Inner Film Electrode Derating Curve Ceramic Substrate 80 1F 60 1H, 1E, 1J, 2A, 2B, 2E, W2H, W3A 40 1E/0.063W (75°C) 1J/0.1W (80°C) 2A/0.125W (85°C) 2B/0.25W, 2E/0.33W (100°C) 2E/0.5W (110°C) W2H/0.75W, W3A/1W (125°C) 60 40 20 20 0 -60 -40 -55 % Rated Power 100 80 % Rated Power 100 -20 0 20 40 60 80 70 Ambient Temperature (°C) 0 -60 -40 -55 100 120 140 125 155 For resistors operated at an ambient temperature of 70°C or above, a power rating shall be derated in accordance with the above derating curve. -20 0 For resistors operated at a terminal part temperature of described for each size or above, a power rating shall be derated in accordance with the above derating curve.
