(0.90 n-m). if a spring clip is used, a clip force of 8 to 30 pounds (35 to 130 n) is recommended to be applied to the center of the package. the clip should be round or smooth in the contact area to avoid concen- trating the load on a small point of the plastic body of the package. another mounting option is to use a pressure bar method which can achieve a greater mounting force with a greater contact area. for additional applications information regarding mounting and pulse handling see the caddock applications notes at caddock.com or contact applications engineering. derating curve specifcations: temperature coeffcient for mp915, mp916, mp925, and mp930: tc referenced to +25c, ?r taken at +150c 0.50 ohms and above, -20 to +80 ppm/c 0.050 ohm to 0.49 ohms, 0 to +200 ppm/c 0.020 ohm to 0.049 ohm, 0 to +300 ppm/c 0.010 ohm to 0.019 ohm, 0 to +500 ppm/c temperature coeffcient for MP9100: tc referenced to +25c, ?r taken at +175c 0.50 ohms and above, -20 to +80 ppm/c 0.050 ohm to 0.49 ohms, 0 to +150 ppm/c operating temperature: -55c to t max inductance: mp915, mp916, mp925, and mp930 10nh typical; MP9100, 20nh typical, in series when measured at a point 0.2 inches from the resistor body. dwv: the dielectric strength rating of 1500 v rms ac is based upon connections made between terminals shorted, and the metal surface the part is mounted to or a metal clip in contact with the top surface of the part. insulation resistance: 10,000 megohms min. the resistor element is electrically isolated from the mounting surface. load stability: 2,000 hours at rated power. ? r (1.0 percent + 0.0005 ohm) max. power rating dependent upon case temperature. see derating curve. momentary overload: 1.5 times rated power with applied voltage not to exceed 1.5 times maximum continuous operating voltage for 5 seconds. ? r (0.5 percent + 0.0005 ohm) max. moisture resistance: mil-std-202, method 106. ? r (0.5 percent + 0.0005 ohm) max. thermal shock: mil-std-202, method 107, cond. f. ? r (0.5 percent + 0.0005 ohm) max. shock: 100g, mil-std-202, method 213, cond. i. ? r (0.4 percent + 0.0005 ohm) max. vibration, high frequency: mil-std-202, method 204, cond. d. ? r (0.4 percent + 0.0005 ohm) max. terminal strength: mil-std-202, method 211, cond. a (pull test) 5 lbs. ?r (0.2 percent + 0.0005 ohm) max. terminal material: solderable measurement note: for these specifications, resistance measurement shall be made at a point 0.2 inch (5.08 mm) from the resistor body. + .030 .004 (.76 .10) .025 .004 (.64 .10) .200 .010 (5.08 .26) .450 .050 (11.43 1.27) .115 .010 (2.92 .26) mp915 0.10 1% .110 .010 (2.79 .26) .053 .007 (1.35 .18) .058 .007 (1.47 .18) .320 .010 (8.12 .26) .094 .004 (2.39 .10) dia. c l .440 .010 (11.18 .26) .080 .020 (2.03 .51) .640 .010 (16.26 .26) .030 .004 (.76 .10) .025 .004 (.64 .10) .200 .010 (5.08 .26) .500 .050 (12.70 1.27) .130 .030 (3.30 .76) .125 .010 (3.18 .26) .410 .010 (10.41 .26) mp930 10.0 1% .125 .010 (3.18 .26) .125 .004 (3.18 .10) dia. c l .053 .007 (1.35 .18) .070 .010 (1.78 .26) mp916 mp915 model no. comments mp930 mp925 to-220 style to-220 style package to-220 style to-126 style 0.010 0.019 0.020 1.00 k min. max. resistance 0.020 4.99 k 5.00k 100 k 16 watts * 15 watts * power rating 30 watts * 25 watts * max. voltage power limited 200 250 500 thermal resistance r jc film ( j ) to case ( c ) 8.33c/watt 5.00c/watt 4.17c/watt 7.81c/watt 150c figure 2 figure 1 dimensions figure 2 figure 2 max. temp. t max 150c 150c 150c MP9100 to-247 style 0.050 100 100 watts * 1.50c/watt figure 3 175c power limited ceramic mounting surface ceramic mounting surface ceramic mounting surface ceramic mounting surface ceramic mounting surface figure 1 to-126 style mp915 figure 2 to-220 style mp916, mp925 and mp930 0.143 0.004 (3.63 0.10) dia. 0.620 0.010 (15.75 0.26) 0.110 0.030 (2.79 0.76) 0.570 0.050 (14.48 1.27) 0.195 0.010 (4.95 0.26) 0.095 0.010 (2.41 0.26) 0.143 0.007 (3.63 0.18) 0.060 0.004 (1.52 0.10) 0.400 0.010 (10.16 0.26) 0.210 0.010 (5.33 0.26) 0.815 0.010 (20.70 0.26) c l mp 9100 50.0 1% 0.032 +0.004 / -0.010 (0.81 +0.10 / -0.26) * derating using case temperature (t c ): page 2 of 2 ? 2003-2017 caddock electronics, inc. e-mail: caddock@caddock.com ? web: www.caddock.com for caddock distributors listed by country see caddock.com/contact/dist.html electronics, inc.
