TO220 50W HIGH POWER RESISTORS

RNP-50U
AEC-Q200Features and Applications
50W high power resistors in TO220 style mold package for through-hole and screw mounting.
AEC-Q200 test certified.
Non-inductive design suits high frequency applications and high-speed pulse circuits.
Low, 2.3 °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 20 milliohm to 510kohm wide resistance range, non-inductive impedance characteristic and heatconduction 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 5.27mm +/-0.6 mm 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 5.27mm from bottom of molding of terminals.
2(4) Test method is IEC60068-2-6, and specification is sine sweep wave form, 100Hz-2000Hz, 10 cycles, amplitude 0.75mm2 or 100m/s ,90minutes. direction x-y z, Amplitude 0.75mm will be applied under break point Frequency (about 60Hz) and 100m/ s over breakpoint(5) When mounting resistor on heat-sink by screw, clip and pressure strip with using heat conduction grease on back side of resistor arerecommended. Recommended screw torque is 0.5-0.6Nm.
(6) Standard packaging is anti-static PE tray, which contains 100pcs / tray.
