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.

㈢Tolerance:
  J=±5%，K=±10%，L=±20%
㈣TCR:
  -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)
