Features N/A
  • Extremely low temperature coefficient of resistance
  • Very low noise and voltage coefficient
  • Very good high frequency characteristics
  • Can replace wirewound bobbins
  • Proprietary epoxy coating provides superior moisture protection
  • 1 For operation of the PTF resistors at higher power ratings, see the Load Life Shift Due to Power and Derating table. This table gives a summary of the effects of using the PTF product at the more common combinations of power rating and case size, as well as quantifies the load life stability under those conditions.
  • 2 Continuous working voltage shall be √P x R or maximum working voltage, whichever is less.
