FeATuRes

  • Radial construction for direct insertion into printed circuit boards; fit standard 0.10 inch matrix boards with standard 0.046 inch diameter holes. Provides a built in stand-off to reduce board temperature.
  • Space saving radial terminals reduce the total length require- ment compared to axial terminal resistors and increase packaging density possibilities.
  • Flame resistant lead free vitre- ous enamel coating.
  • RoHS compliant; add “E” suffix to part number to specify. Dimensions (in. / mm) series Wattage Ohms Length Height Diam. Dim.

Coating: Vitreous enamel except for values above 4.7K (3W) and 7.5K (5W), which are supplied in silicone-ceramic coatings. Terminals: Solder coated radial. #20 ga. tinned terminals require 0.046 in. (1.168 mm) holes (2). RoHS solder composition is 96% Sn, 3.5% Ag, 0.5% Cu Derating: Linearly from +350°C. Note: Values above 3.9K (3W) and 8.2K (5W) involve very fine resistance wire and should not be used in critical applications without burn-in and/or thermal cycling. Electrical Tolerance: ±5% (J) (other tolerances available). Power rating: Based on 25°C free air rating. Overload: 3 watt: 5 times rated wattage for 5 seconds. 5.25 watt: 10 times rated watt- age for 5 seconds. Temperature coefficient: ±260 ppm/°C. To calculate max. amps: use the formula √P/R.
