High Power Load Resistors (300W–10,000W)

Short Description:

The RX20 corrugated wirewound resistor uses selected alloy wire, vertical corrugated winding, a high-temperature ceramic tube, moisture-proof coating, and a thickened galvanized stainless steel bracket. Its advantages include excellent heat dissipation, low parasitic inductance, stable resistance, and high reliability against heat, moisture, and corrosion.


  • Rated power: 300W-10KW
  • Resistance value: 0.1-5K Ohm
  • Resistance value accuracy: F(±1%) J(±5%)
