TO263 SURFACE MOUNT35W HIGH POWER RESISTORSRNP-20DFeatures and Applications
35W high power resistors in TO263 (D2-PAK) style surface mount mold package.
Non-inductive design suits high frequency applications and high-speed pulse circuits.
Low, 3.3 °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 milliΩ to 510K Ω resistance range, non-inductive impedance characteristic and heat venting through insulated
metal flange aids circuit designers.
Small size and thin profile suits high-density compact installations.
RNP-20D has a Ni plated copper flange, when matte tin plating is necessary refer to RNP-20E
Complete thermal conduction, heat dissipation design and vibration durable design to be available.
Applications for UPS, power unit of machines, motor control, drive circuits, automotive, measurements, computers and highfrequency electronics.

Recommended Land Pattern. (mm)Additional heat cooling system will be necessary

When joint on printed circuit board, reflow soldering by furnace with another parts shall not be recommended. After mounting another parts
and after pre-coating solder on to land pattern, dip flange and leads in to soldering resin, place RNP-20D resistor on the land pattern, andheat flange for 20-30 seconds by soldering iron which iron tip temperature is 300-350 °C. Flange temperature shall be in 270+/-10 °C for
30 seconds. A better result will be obtained if flange is pre-coating solder. Please note using soldering flux and large caloric capacity.
