50W TO220 HIGH POWER RESISTORS
RNP50U
Features and Applications
50W high power resistors in TO220 molded package, through-hole and surface mount.
Non-inductive design suits for high frequency applications and high-speed pulse circuits.
Low, 2.3 C/W heat resistance from resistor hot spot to flange is presented through thin film
metalization technology.
Wide, 100mohm to 220ohm resistance range, non-inductive impedance characteristic and heat
venting through insulated metal flange aids circuit designers. Small size and thin profile suits for
high-density compact installations. Complete thermal conduction, heat dissipation design and
vibration durable design to be available.
Applications in SW PS, power units of machines, motor controls, drive circuits, automotive,
measurements, and industrial computers.

Note:
(1) Insulating material is not necessary between flange and resistors , flange and resistor is separated by alumina
substrate.
(2) At surface mount soldering, temperature profile in tab shall not exceed 220C.
(3) Using heat conduction grease on surface of flange is recommended.
(4) Heat resistance between resistor and tab is 2.3 C/W. Heat design will be done, as resistor temperature shall be
under 155C in operation.
(5) 0.1% tolerance resistors and over 220ohm resistance are available, please call factory.
