Features and Applications
Up to 140W high power rating at 25C mount screw temperature cased in TO-247 mold package.
Only 0.9C/W thermal resistance from resistor surface to flange or metal back plate are realized.
Complete thermal conduction and heat transfer design is available.
Linear temperature raise / applied power characteristics are realized.
Exposed high thermal conduction metal is useful for excellent heat transfer to outer heat sink.
Insulation sheet is unnecessary, sufficient insulation between circuit and back metal is supported at internal structure.
Non-inductive designs effective in wide frequency range.
Small size 100W power resistors and thin type fit for higher density design at power electronics.
RNP100S will be applied to such industrial power equipments and RF circuits as UPS, motor control, power amplifier,
RF power amplifier, automated machine control and power supplies.
Recommendation
Flat surface heat sink, thermal compound and sufficient mount screw torque will be necessary for well heat transfer.
In rush current protection application as charge current limitation resistor, sufficient power derating will be necessary.
