TO263 SURFACE MOUNT50W HIGH POWER RESISTORS

RNP-50FFeatures and Applications

50W high power resistors, high soldering temperature in TO263 (D2PAK) style surface mount moldpackage with matte Tin plated flange.
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.
Wide, 20 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,industrial computers and high frequency electronics.
