Product Overview

The HS300 4R F from Arcol/Ohmite is HS series 300W aluminium housed resistor. Manufactured in line with the requirements of MIL 18546 and IEC 115, designed for direct heatsink mounting with thermal compound to achieve maximum performance. The wire wound design is used to maximise the high pulse characteristics, the power dissipates linearly to zero, even at high ambient temperatures. Its advanced design optimises stability, linearity and reliability making the HS resistors suitable for many applications including braking resistor, inrush limiter, inverter/converter, snubber and balancing resistor.
  • Resistance value is 4ohm with 1% tolerance
  • Temperature coefficient is 100ppm
  • Minimum insulation resistance is 10000Mohm
  • Limiting element voltage is 2500V
  • Voltage proof AC RMS is 5000V
  • Power rating without heatsink is 60W
  • High Power Resistor
