  Ⅸ.Custom Solutions Readily Available

㈡Application:
     HJR High Energy  resistors are most  often   usedfor  low  repetition rate discharge,

  crowbar,pulse  shaping or  other  impulse duty. In  practice, a resistor or  combination

  is selected  to yield  nomore than 100oC rise for the expected applied energy.Because of

  the  large mass, a relatively long cooling time is  required between pulses,or additional

  heat capacity must be allowed for.Ourapplications spreadsheet(MS Excel,available ondiskette)

  can beused to easily model heat-up and cool-down profiles for your specific application.
Tolerance:
  J=±5%,K=±10%,L=±20%
TCR:
  -0.05% to -0.15% per °C Temperature Rise depending on Resistivity Value.
  TCR = 0.16 x e-(logρ/1.4) - 0.135 (%/°C Temperature Rise)
