RoHS2POWER – NIKKOHM

TO247 140W HIGH POWER RESISTORS・RNP-100S (27.5mm lead length)

Features and Applications
Up to 140W high power rating at 25 °C flange temperature cased in TO-247 mold package.
Only 0.9C/W thermal resistance from resistor surface to flange or metal back plate are realized.
Flexible lead terminal for easy mounting, lead total length 27.5 mm. The lead length of 27.5 mm isindicated by Z00 at the end of the part number.
Insulation sheet is unnecessary, sufficient insulation between circuit and back metal is supported atinternal structure.
Small size 100W power resistors and thin type fit for higher density design at power electronics.
RNP-100S will be applied to such industrial power equipments and radio frequency circuits as UPS, motorcontrol, power amplifier, RF power amplifier, automated machine control and power supplies.

Recommendation(1) Flat surface heat sink, thermal compound andsufficient mount screw torque (0.5Nm-0.6Nm) will
be necessary for well heat transfer.
(2) In rush current protection application as charge
current limitation resistor, sufficient power derating
will be necessary.
(3) Flammability is UL94V-0,(4) Recommended screw torque is 0.5-0.6Nm.
