TO263 SURFACE MOUNT35W HIGH POWER RESISTORSRNP-20FFeatures and Applications

35W high power resistors in TO263 (D2-PAK) style surface mount mold package with matte Tin plated flange.
The reflow heat durable structure and materials of RNP-20F is easy to assemble as compared with RNP-20E orRNP-20D.
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.
Wide, 10 mΩ to 51K Ω resistance range, non-inductive impedance characteristic and heat extracting through insulated
metal flange aids circuit designers.
Applications for UPS, power unit of machines, motor control, drive circuits, automotive, measurements, computers andhigh frequency electronics.
