40 Series

Ohmicone® Silicone-Ceramic Conformal Axial Terminal Wirewound 1% and 5% Tolerance Standard Coating Conformal silicone-ceramic. Core Ceramic. Terminals Solder-coated copper clad axial. RoHS solder composition is 96% Sn, 3.5% Ag, 0.5% Cu Derating Linearly from 100% @ +25°C to 0% @ +275°C. Tolerance ±5% (J type), ±1% (F type) (other tolerances available). Power rating Based on 25°C free air rating Overload Under 5 watts: 5 times rated wattage for 5 seconds. 5 watts and over: 10 times rated wattage for 5 seconds. Temperature coefficient Under 1Ω: ±90 ppm/°C; 1Ω to 9.99Ω: ±50 ppm/°C; 10Ω and over: ±20 ppm/°C Series Wattage Length Diam. Lead ga.

  • Economical
  • Applications include commercial, industrial and communications equipment
  • Stability under high temperature conditions
  • All-welded construction
  • RoHS compliant; add “E” suffix to part number to specify. Ohmite 40 Series resistors are the most economical conformal silicone-ceramic coated resistors offered. These all-welded units are characterized by their low temperature coefficients and resistance to thermal shock, making them ideal for a wide range of electri- cal and electronic applications. Units with 1% and 5% tolerances are identical in construction and electrical specifications. Durable but economical 40 Series resistors exceed industry requirements for quality.
