POWER RESISTORS - FLAMEPROOF RoHS (M)SQ(H, M, P, T, U, Z) Series: Cement Box INTRODUCTION PART NUMBER EXAMPLE 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: MSQM 5W - 47K - J Tolerance Series ( + 5% + 10%) Size Code SQ MSQ NSQ - Standard wire wound (all welded construction) - Metal oxide core (low inductance, high resistance) - Non-Inductively wound (Ayrton-Perry Method, all welded construction) Resistance RESISTANCE Ohms 0.22 2.0 22 220 2.2K 22K Code 0R22 2R0 22R 220R 2K2 22K DIMENSION & RESISTANCE RANGE Series SQP1W SQP2W SQP3W SQP5W SQP7W SQP10W SQP15W SQP20W SQP25W SQT5W SQT7W SQT10W SQT15W SQM2W SQM3W SQM5W SQM7W SQM10W SQMX10W SQMX12.5W SQZ5W SQZ7W SQZ10W SQZ15W SQZ20W SQZ25W SQH SQU10W SQU15W SQU20W SQU30W SQU40W W 6+1 7+1 8+1 10 + 1 10 + 1 10 + 1 12.5 + 1 14 + 1 14 + 1 W 10 + 1 10 + 1 10 + 1 12.7 + 1 W 11 + 1 11 + 1 13 + 1 13 + 1 13 + 1 16 + 1 16 + 1 W 10 + 1 10 + 1 10 + 1 12 + 1 12 + 1 12 + 1 H 6+1 7+1 8+1 9+1 9+1 9+1 11.5 + 1 13.5 + 1 13.5 + 1 H 9+1 9+1 9+1 12.7 + 1 H 20.5 + 1.5 20.5 + 1.5 25 + 1.5 39 + 1.5 51 + 1.5 35 + 1.5 35 + 1.5 H 10 + 1 10 + 1 12 + 1 12.5 + 1 12.5 + 1 12.5 + 1 W H 10 + 1 9+1 12.5 + 1 11.5 + 1 12.5 + 1 13.5 + 1 19 + 1 19 + 1 19 + 1 19 + 1 Dimension (mm Resistance Range P (SQH Series) L d SQ_ MSQ_ 14 + 1 0.6 + 0.05 0.01 ~ 75 1.0 ~ 33K 18 + 1.5 0.65 + 0.05 0.01 ~ 100 1.0 ~ 33K 22 + 1.5 0.8 + 0.05 0.01 ~ 300 1.0 ~ 100K 5+1 22 + 1.5 0.8 + 0.05 0.01 ~ 300 1.0 ~ 100K 10 + 1 35 + 1.5 0.8 + 0.05 0.1 ~ 600 1.0 ~ 100K 10 + 1 48 + 1.5 0.8 + 0.05 0.1 ~ 1.2K 1.0 ~ 100K 48 + 1.5 0.8 + 0.05 0.5 ~ 1.5K 60 + 1.5 0.8 + 0.05 0.5 ~ 1.5K 60 + 1.5 0.8 + 0.05 0.5 ~ 1.5K L T SQ_ MSQ_ 22 + 1.5 1.5 + 0.5 0.1 ~ 600 1.0 ~ 100K 35 + 1.5 3.0 + 0.5 0.1 ~ 1.2K 1.0 ~ 100K 48 + 1.5 3.0 + 0.5 0.5 ~ 1.5K 49 + 1 2.8 + 1 0.1 ~ 1.2K T P SQ_ MSQ_ 7+1 5 0.01 ~ 100 1.0 ~ 33K 7+1 5 0.01 ~ 100 1.0 ~ 33K 9+1 5 0.01 ~ 300 1.0 ~ 100K 9+1 5 0.1 ~ 500 1.0 ~ 100K 9+1 5 0.1 ~ 600 1.0 ~ 75K 12 + 1 7.5 0.1 ~ 360 1.0 ~ 100K 12 + 1 7.5 0.1 ~ 600 L P H1 P1 P2 SQ_ MSQ_ 27 + 1.5 15 + 1 10.5 + 1 4.5 ~ 7.5 1.6 + 0.2 0.01 ~ 300 1.0 ~ 50K 35 + 1.5 20 + 1 10.5 + 1 7+1 1.6 + 0.2 0.1 ~ 600 1.0 ~ 50K 48 + 1.5 32 + 1 10.5 + 1 7+1 1.6 + 0.2 0.1 ~ 600 1.0 ~ 50K 48 + 1.5 32 + 1 15 + 1 10 + 1 3 + 0.2 0.1 ~ 1K 62 + 1.5 42 + 1 15 + 1 10 + 1 3 + 0.2 0.1 ~ 1K 62 + 1.5 42 + 1 15 + 1 10 + 1 3 + 0.2 0.1 ~ 1K 5W to 10W specifications are the same as SQP5W to 10W L 48 + 1 48 + 1 63 + 1 75 + 1 90 + 1 P 35 + 1 32 + 1 44 + 1 55 + 1 70 + 1 H1 18 + 1 21 + 1 21 + 1 32 + 1 32 + 1 T 0.4 0.4 0.4 0.8 0.8 Diagram A A A B B SQ_ 0.1 ~ 270 1 ~ 470 1 ~ 560 1 ~ 820 1 ~ 1K MSQ_ 271 ~ 50K 471 ~ 150K 561 ~ 150K 821 ~ 150K 1.1K ~ 150K SQP d H L 35 + 3 W SQT 35 + 3 H T W T W H 4.0 min P+1 0.8 + 0.05 SQZ P P1 P2 4.5mm nom < 10W 7.5mm nom > 15W 0.4 H1 H L W SQH 10.5 + 0.05 W L P 4 + 0.5 10.5 + 0.05 H Termination 5+3 SQU T P 6.2 ±0.1 2.4 H L Page 1 of 2 0.8 + 0.05 L SQM W Diagram A RFE International • Tel:(949) 833-1988 • Fax:(949) 833-1788 • E-Mail [email protected] H1 6.4 ±0.1 1.65 H H1 W Diagram B C2DC01 2014.06.17 POWER RESISTORS - FLAMEPROOF RoHS (M)SQ(H, M, P, T, U, Z) Series: Cement Box ELECTRICAL CHARACTERISTICS Test Items Wirewound Resistance Temp.
