TO247 140W HIGH POWER RESISTORSRNP-100S
Features and Applications
140W high power resistor in TO247 molded package.
Non-inductive design suits high frequency applications and high-speed pulse circuits.
Low, 0.9 deg C/W heat resistance from resistor hot spot to flange and long life performance are presented
with thin film metallization technology and rejection of plastic adhesive joint.
Wide 100 milliohm to 51kOhm resistance range, non-inductive impedance characteristic and heat
conduction through the insulated metal flange aids circuit designers.
Small size and thin profile suit high-density compact installations.
Complete thermal conduction, heat dissipation design and vibration durable design also available.
Applications include snubber, gate control, bleeder, filter, rush current protection, braking resistors ofautomotive, rail traction, wind turbine, PV, UPS and motor control inverters..

Note:
(1) Insulation material is unnecessary between flange and heat-sink, flange and resistor is separated by alumina substrate.
(2) Resistance measurement shall be made at a point 2.54mm+/-1.0mm from the resistor body.
(3) TCR of low resistance will be increased as 300ppm/0.02ohm, 200ppm/0.05ohm, 140ppm/0.1ohm and 80ppm/0.2ohm
typically. Testing point is at 2.54mm from bottom of molding of terminals.
(4) Test method is IEC60068-2-6, and specification is sine sweep wave form, 100Hz-2000Hz, 10 cycles, amplitude 0.75mm
or 100m/s2, 90minutes. Direction x-y-z, Amplitude 0.75mm will be applied under break point Frequency (about 60Hz)
and 100m/ s2 over break point(5) When mounting resistor on heat-sink by screw, clip and pressure strip with using heat conduction grease on back sideof resistor are recommended. Recommended screw torque is 0.5-0.6Nm. In case of screw mount, ISO M3 screw isnecessary, also,1/8” screw can be acceptable.
(6) Standard packaging is anti-static PE tube, which contains 25 pcs / tube.
