h.e.i. axial lead resistors are constructed with steatite ceramic cores or alumina, terminated with welded cap and lead assemblies and wound with the finest alloy resistance wires welded to the cap and lead assemblies. our special formula of vitreous enamel ( alvr ) or silicone ( alsr ) coatings are then used to insulate the resistors. this construction insures long life, durability, and reliability. h.e.i. axial lead resistors are especially suited for printed circuitry applications and wherever miniaturization is required. alvr alsr axial lead wirewound resistors 1 watt thru 10 watt alvr - vitreous alsr - silicone a c e d type watt a .032 (0.8) c .032 (0.8) d typ. e typ. alvr-1 ALSR-1 1 1 .125 (3.2) .110 (2.8) .437 (11.1) .385 (9.8) .020 (0.5) .020 (0.5) 1.5 (38) 1.5 (38) alvr-3 alsr-3 3 3 .218 (5.5) .200 (5.1) .563 (14.3) .530 (13.5) .032 (0.8) .032 (0.8) 1.5 (38) 1.5 (38) alvr-5a alsr-5a 5 5 .218 (5.5) .200 (5.1) 1.031 (26.2) .937 (23.8) .032 (0.8) .032 (0.8) 1.5 (38) 1.5 (38) alvr-5 alsr-5 5/7 5/7 .343 (8.7) .312 (7.9) 1.031 (26.2) .937 (23.8) .032 (0.8) .032 (0.8) 1.5 (38) 1.5 (38) alvr-10 ALSR-10 10 10 .343 (8.7) .312 (7.9) 1.843 (46.8) 1.800 (45.7) .032 (0.8) .032 (0.8) 1.5 (38) 1.5 (38) environmental specifications test mil-r-26 load life (3% + .05 ? )> ? r moisture resistance (2%+.05 ? )> ? r 90 ppm/ 8 c below 1 ? temp. coefficient 50 ppm/ 8 c 1w to 9.9 ? 30 ppm/ 8 c 10w and above thermal shock (2% + .05 ? ) >r short time overload (2% + .05 ? ) >r dielectric (.1% + .05 ? ) >r low temp. storage (2% + .05 ? ) >r high temp. storage (2% + .05 ? ) >r shock (.2% + .05 ? ) >r vibration (.2% + .05 ? ) >r terminal strength (1% + .05 ? ) >r optional features available resistance tolerance: standard tolerance is 5% (j) for 1 ohm, and greater and 10% (k) for less than 1 ohm. available tolerances: f = 1%, j = 5%, k = 10% non-inductive: ayrton-perry type non-inductive winding is available. when required add ni to the part number. leads: hot tin-dipped leads with dimensions as shown in the above chart are standard. however, special lead lengths and diameters are available. for further infromation please contact our sales office. mechanical terminal strength: 10 lb. pull test huntington electric, inc. 1 p.o. box 366 1 huntington, in 46750 1 (260) 356-0756 1 www.heiresistors.com alvrj - 10 - 100 - ni type v=vitreous s=silicone resistance value include for tolerance add for non-inductive power order information .10 .75 10 30 68 125 300 600 1.1k 3.0k 6.8k .13 1.0 12 33 75 150 330 680 1.2k 3.5k 7.5k .15 1.5 15 35 82 180 350 700 1.5k 3.9k 8.0k .20 2.0 18 39 100 200 390 750 1.8k 4.0k 8.2k .25 3.0 20 40 120 220 400 800 2.0k 4.7k 10.0k .30 4.0 22 47 125 225 470 820 2.2k 5.0k 12.5k .33 5.0 25 50 150 250 500 900 2.5k 5.6k 15.0k .50 7.5 27 56 180 270 560 1.0k 2.7k 6.0k 20.0k resistance value chart 0 25 50 75 100 25 50 100 150 200 250 300 350 375 wattage derating chart for higher ambient temperatures ambient temp. c l % rated load
