Power rating: Rating is based on chassis mounting area and temperature stability. Proper heat sink as follows: 5W and 10W units, 4" x 6" x 2" x .040" Aluminum chassis; 25W units, 5" x 7" x 2" x .040" Aluminum chassis; 50W units, 12" x 12" x .059" Aluminum panel. Maximum ohmic values: See chart. Overload: 5 times rated wattage for 5 seconds. Temperature coefficient: Under 1: 90 ppm/C 1 to 9.99: 50 ppm/C 10 and over: 20 ppm/C. Dielectric withstanding voltage: 5W and 10W rating,1000 VAC; 25 and 50W ratings, 2250 VAC. FEATURES Series 805 = 5 Watt 810 = 10 watt 825 = 25 watt 850 = 50 watt 89 Series SPECIFICATIONS The 89 Series is a high-performance axial type resistor. These molded-construction metal-housed resistors are available in higher power ratings than standard axial resistors and are better suited to withstanding vibration, shock and harsh environmental conditions. The 89 Series Metal-Mite(R) resistors are aluminum housed to maintain high stability during operation and to permit secure mounting to chassis surfaces. The metal housing also provides heat-sinking capabilities. 5 watt 10 watt 805 810 Dimensions 1.125 / 28.59 1.375 / 34.93 0.490 / 12.45 0.625 / 15.88 0.078 / 1.98 0.094 / 2.39 0.444 / 11.28 0.562 / 14.28 0.600 / 15.24 0.750 / 19.05 0.266 / 6.76 0.312 / 7.93 0.334 / 8.48 0.438 / 11.13 0.245 / 6.22 0.312 / 7.93 0.646 / 16.41 0.812 / 20.63 0.093 / 2.36 0.094 / 2.39 0.320 / 8.13 0.406 / 10.31 0.133 / 3.38 0.203 / 5.16 0.065 / 1.65 0.094 / 2.39 0.050 / 1.27 0.085 / 2.16 16 12 0.085/ 2.16 0.140/ 3.56 25 watt 825 50 watt 850 1.938 / 49.23 0.781 / 19.84 0.172 / 4.37 0.719 / 18.26 1.062 / 26.98 0.438 / 11.13 0.531 / 13.49 0.391 / 9.93 1.094 / 27.79 0.125 / 3.18 0.562 / 14.28 0.281 / 7.14 0.094 / 2.39 0.085 / 2.16 12 0.140/ 3.56 2.781 / 70.64 0.844 / 21.44 0.188 / 4.78 1.562 / 39.68 1.938 / 49.23 0.438 / 11.13 0.594 / 15.09 0.422 / 10.72 1.156 / 29.36 0.125 / 3.18 0.625 / 15.88 0.312 / 7.92 0.094 / 2.39 0.085 / 2.16 12 0.140/ 3.56 S TA N D A R D PA RT N U M B E R S 1,500 2,000 2,500 3,000 3,500 4,000 4,500 5,000 6,000 10,000 15,000 20,000 25,000 50,000 75,000 100,000 850F--- 50 825F--- 25 Part No. Prefix Suffix ---1K5 ---2K0 ---2K5 ---3K0 ---3K5 ---4K0 ---4K5 ---5K0 ---6K0 ---10K ---15K ---20K ---25K ---50K ---75K ---100K 805F--- 5 810F--- 10 Ohmic value 850F--- 50 20 25 30 40 50 75 100 150 200 250 300 400 500 750 1,000 825F--- 25 805F--- 5 810F--- 10 Ohmic value 825F--- 25 850F--- 50 805F--- 5 810F--- 10 Part No. Prefix Suffix ---20R ---25R ---30R ---40R ---50R ---75R ---100 ---150 ---200 ---250 ---300 ---400 ---500 ---750 ---1K0 Wattage Part No. Prefix Suffix 0.005---R005 0.010---R010 0.025---R025 0.1 ---R10 0.3 ---R30 0.5 ---R50 0.7 ---R70 1.0 ---1R0 1.5 ---1R5 2.0 ---2R0 3.0 ---3R0 4.0 ---4R0 5.0 ---5R0 10.0 ---10R 15.0 ---15R Wattage Ohmic value Wattage = Standard values = Non-standard values subject to minimum handling charge per item Shaded values involve very fine resistance wire and should not be used in critical applications without burn-in and/or thermal cycling.
