DBL
TO247 140W HIGH POWER RESISTORS
Lead Free
RNP100S
Features and Applications
Up to 140W high power rating at 25C flange temperature cased in TO-247 mold package.
Just 0.9C/W thermal resistance from resistor surface to flange or metal back plate realized.
Complete thermal conduction and heat transfer design available.
Linear temperature raise/applied power characteristics realized.
Exposed high thermal conduction metal useful in excellent heat transfer to outer heat sink.
Insulation sheet unnecessary, sufficient insulation between circuit and back metal supported in internal
structure.
Non-inductive design effective in wide frequency range.
Small size 100W power resistors and thin type fit for higher density design of power electronics.
RNP100S will be applicable in such industrial power equipment and radio frequency circuits as UPS,
motor control, power amplifiers, RF power amplifiers, automated machine controls and power supplies.
