RoHS POWER RESISTORS ü (M)SQ(H, M, P, T, U, Z) Series: Cement Box INTRODUCTION CHARACTERISTICS Cement-Box type resistors offer a choice of resistive elements inside a white flameproof cement box. In addition to being flameproof, these resistors are also non-corrosive and humidity proof. The available resistive elements are: SQ MSQ Test Items Wirewound Resistance Temp. Coeff. Metal Oxide Resistance Temp. Coeff. Moisture Load Life Cycle Test Standard Tolerance - Standard wire wound (all welded construction) - Metal oxide core (low inductance, high resistance) - Non-Inductively wound (Ayrton-Perry Method, all welded construction) - Fiber Glass Core NSQ GSQ 25 C 100 250 20W 15W 10W 7W 5W 2 & 3W 200 150 100 50 0 DERATING CURVE 70 C 155 C 275 C 2 ~ 10W 80 60 15 & 20W 40 -50 20 40 60 80 100 120 Load Factor (%) SPECIFICATIONS Series 0 50 100 150 200 Ambient Temperature ( C) 250 300 -55 °C ~ +200°C +3% 40°C 95° @ RH 1,000hrs J = +5%, K = +10% -25°C 500V 750V 1000V +2% + 0.05 2W, 3W, 5W, 7W 10W 15W, 20W, 25W 1000V, 1 min 2 500Vdc, 1 min +(2% + 0.05 ¿ ) 1000V, 1 min 70°C for 1000 hours 40°C, 90% RH, +5% + 0.05¿ 1000 hours 95% coverage min. 230°C, 5 sec. +(5% + 0.05 ¿ ) Solderability Resistance to Solder Heat +(2% + 0.05¿ ) 260°C, 10 sec. *Maximum Voltage per value to be determined by Ohms Law but not to exceed noted voltage.
