Construction
Surface Mount Resistors/Flat Chip Jumper Resistors RK73Z
Surface Mount Resistors/Flat Chip Jumper Resistors RK73Z Construction
  1. Protective coating
  2. Resistive film
  3. Inner electrode
  4. Ni Plating
  5. Sn plating
  6. Ceramic Substrate

Features

  • Small and light weight.
  • Excellent heat resistance and weather resistance, because of the use of glaze thick film as resistive film.
  • High stability and high reliability because of the triple-layer structure of electrode.
  • Applicable to various kinds of automatic mounters for taping, etc.
  • Suitable for both flow and reflow solderings.
  • Products with lead free termination meet EU-RoHS requirements.
    EU-RoHS regulation is not intended for Pb-glass contained in electrode, resistor element and glass.
  • AEC-Q200 Qualified(Except 1F).

If any questions arise whether to use the“Rated Ambient Temperature”or the“Rated Terminal Part Temperature”in your usage conditions, please give priority to the“Rated Terminal Part Temperature”. For more details, please refer to“Introduction of the derating curves based on the terminal part temperature”

Derating Curve

Surface Mount Resistors/Flat Chip Jumper Resistors RK73Z Derating Curve
For resistors operated at an ambient temperature of 70°C or above, a current rating shall be derated in accordance with derating curve on the left.
Surface Mount Resistors/Flat Chip Jumper Resistors RK73Z Derating Curve

For resistors operated at an terminal part temperature of described for each size or above, a current rating shall be derated in accordance with derating curve.
※ Please refer to “Introduction of the derating curves based on the terminal part temperature” before use.
