TT electronics (United Kingdom) has introduced a comprehensive range of wirewound resistors offering surge energy ratings from 2 to 7 W sizes. Suitable for a wide range of pulse applications, the WHS series flameproof resistor is aimed, particularly, at designers of power supplies requiring a line input resistor for inrush limiting and protection. Features include:

  • A high-purity ceramic substrate that is assembled with interference fit end-caps welded to the terminations.
  • Surge energy ratings of 0.9 to 5.8 J.
  • Availability in resistance values up to 330 Ω and taking energy ratings up to 60 J.
  • A temperature range of -55° to +155°C.
