Lead Free Vitreous enamel Molded axial term. Wirewound, 5% tolerance standard
- RoHS compliant; add “E” suffix to part number to specify. speciFications Material Coating: Molded lead free vitre- ous enamel. Core: Ceramic. Terminals: Solder-coated copper clad axial. RoHS solder com- position is 96% Sn, 3.5% Ag, 0.5% Cu Derating: Linearly from 100% @ +25°C to 0% @ +350°C. Electrical Tolerance: ±5% (other tolerances available). Power rating: Based on 25°C free air rating. (other wattages available*). Maximum ohmic values: See chart. Overload: Under 11 watts: 5 times rated wattage for 5 seconds. 11 watts: 10 times rated wattage for 5 seconds. Temperature coefficient: 1 to 9.99Ω: ±100 ppm/°C 10Ω and over: ±30 ppm/°C Dielectric withstanding voltage:
500 VAC: 1W rating
1000 VAC: 2, 3, 5 and 11W
