POWER-NIKKOHM

RoHS 245W DPAK-TO252 STYLE
SMD SURGE PROTECTION RESISTOR

RNP-45(AEC-Q200)

Features and Applications
Very small size, low profile, right weight, TO252 style, SMD surge protection power film resistors.
-55°C to +175°C temperature range provides for automotive applications.
Low thermal resistance under 1.0 °C/W shows excellent cooling performance.
Easy to replace TO252 D-PAK power resistor.
Excellent rf characteristics advantage to high speed pulse operation.
Applications include snubber, gate control, bleeder, filter, rush current protection, braking resistors ofautomotive, rail traction, wind turbine, PV, UPS and motor control inverters.
