The ULF150C flat type metal clad wire wound resistor series from RARA, offers a power rating of up to 150W on a heat sink and available resistance values between 1Ω and 1.75kΩ. These UL approved high power and low inductance resistors are designed for industrial and other applications where space is at a premium, the flat design also allows for excellent heat dissipation. The ULF150C series from RARA offers an extruded aluminium housing providing strong and rugged protection, with cement filling material as well as tolerances as low as ±0.5%. This resistor series offers a temperature range from -55°C up to +200°C.
Typical applications for the ULN series include:
