3R-100

      The 3R-100 is designed as 100W mountable non-inductive and high frequency resistors.It is ideally suites for high frequency and pulse load applications. By direct mounting on a heatsink significant cost advantages can be reailzed.Main applications of the 3R-100 are variable speed drives, power supplies, control devices, telecom, robotics, motor controls, dynamic braking, and other switching designs, RF applications, soft start.
      3R-100 has seven features.The first one is it would be heat sink mountable.The second one is RF termonal.The next one is it would be shunt.The next one is inverter.The next one is motor braking.The next one is pulse & plasma.The next one is that it would use medium voltage.That are all the fretures.
      Some electrical specifications and absolute maximum ratings of the 3R-100 have been concluded into several points as follow.The first one is tolerance which would be 5%, 10% std. (1% ,2% custom).The next one is about its TCR which would be ± 100ppm/ std.The next one is about the power rating of the 3R-100 which would be 100W at 25 °C tap temperature.The next one is about its working voltage which would be less than 1kV rms. (higher voltage see "DON-15" package device).The next one is about its resistance range which would be 1R to 5Meg.The next one is about its voltage proof which would be dielectric strength 4kVdc against ground.The next one is about the inductance of the 3R-100 which would be 50 nH.The next one is about its capacitance which would be 40pF.The next one is about its working temp. range which would be from -55°C to +155°C.The nest one is about its max. torque for contacts (static) which would be 1.3Nm.The next one is about its max. torque for base plate (static) which would be 1.5Nm.The next one is about its resistive material which would be thick film.The next one is about its resistive substrates which would be alumina.The next one is about its tap material which would be Ni plated copper plates.The next one is about its housing which would be EMC.The next one is about its terminal which would be tinned copper; 2-pin,3-pin,4-pin. The next one is about its partial discharging which would be 2kV rms / 80pC.And so on.For more information about the 3R-100 please contact us.
