Assortments

Articles from this product series can be found in the following assortments:

Comments

  • The ambient temperature when operating the WE-PD series of storage chokes at full current rating load should generally range from –40 °C to +85 °C.
  • The self-heating of the component must be taken into account at higher ambient temperatures in order that the permissible solder joint temperature is not exceeded or the wire insulation damaged.
  • The wire used can withstand a temperature of up to +150 °C.
  • The ferrite core itself may be used over a far greater temperature range (approx. –50 °C to +250 °C (curie temperature))
  • However, in this case, the tolerance limits of the inductor may be exceeded due to the temperature dependence of permeability.
