Dubilier DWR Power wire wound resistor Datasheet

Power Wire Wound Resistors
Resistors
Operating temperature -40°C to +200°C
1W to 10W
Flame Proof and High Power
The DWR series is available in power ratings from 1W to 10W
With tolerances of 5% and 10%
The resistors are coated in green lacquer of flameproof silicone,
The 5th colour band is violet to represent power wire wound
Resistors. High power dissipation in small volume
