APPLICATIONS 1 kΩ to 10 kΩ 220 Ω to 910 Ω ±10%; ±20%; E12 series 0.5 W 120 K/W 0 to +600 × 10−6/K −600 to +200 × 10−6/K 0 to +350 × 10−6/K Application for overload and high voltage pulse hazard circuits (TV-sets, monitors). DESCRIPTION A metal glazed film is deposited on a high grade ceramic body. After that caps are applied to the rods and electrolytic copper wires are welded to these end caps. The resistors are coated with a light-blue lacquer which provides electrical, mechanical and climatic protection. The encapsulation is resistant to...
