Features

  • Current detecting resistors for power supply, motor circuits, etc.
  • High reliability and performance with resistance tolerance 0.5%, T.C.R. 10010-6/K.
  • Suitable for both reflow and flow solderings.
  • Products with lead-free termination meet EU-RoHS requirements.
  • AEC-Q200 qualified (Exemption 1H).

Applications

  • Car electronics, Computers, HDDs, Cellular-telephones, Power supplies, and Motor circuits, etc.

Derating Curve

For resistors operated at an ambient temperature of 70 or above, a power rating shall be derated in accordance with the derating curve. For resistors operated at terminal part temperature of described for each size or above, a power rating shall be derated in accordance with derating curve.

Precautions for Use

  • Cracks may occur at the solder connection due to thermal stress from differences in thermal expansion coefficients between the chip resistor and the mounting board, especially with larger types (W2H, W3A, W3A2) which have greater thermal expansion and self-heating. Careful design is required for applications with significant ambient temperature fluctuations or repeated load ON/OFF cycles.
  • The resistance value after soldering may change depending on the size of the pad pattern or solder amount. Verify the effect of resistance value changes before finalizing equipment design.
