Product Overview

The Welwyn WHS series are axial leaded wirewound high surge resistors. Resistance range includes E24 decade values from 1ohm to 330 ohm. The UL recognised wire wound fusible resistors are recommended for safety critical use in line input circuits where safe fusing is essential in the event of malfunction. They have reduced body size compared to uprated or multiple standard wirewound parts.
  • Isolation voltage of 250V (WHS2), 350V (WHS3), 500V (WHS5), 700V(WHS7), 1000V (WHS10, WHS10N)
  • Power rating at 25°C is 2W (WHS2), 3W (WHS3), 5W (WHS5), 7W(WHS7), 10W (WHS10, WHS10N)
  • Available in 1%, 2% and 5% tolerance
  • Temperature coefficient of resistance ±200ppm/°C
  • Ambient temperature range from -55°C to +155°C
  • Enhanced surge & pulse energy capacity
  • Radial taped form, non inductive type available
  • Surface mount ZI-form option
