The ULF300C flat type metal clad wire wound resistor series from RARA, offers a power rating of up to 300W on a heat sink and available resistance values between 1ฮฉ and 3.5kฮฉ. 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 ULF300C series from RARA offers an extruded aluminium housing providing strong and rugged protection, with cement filling material as well as tolerances as low as ยฑ0.5%. This resistor series offers a temperature range from -55ยฐC up to +200ยฐC.
Typical applications for the ULF series include:
