Aluminum Housed Resistor (RH Series)

JDC RH aluminum housed resistors are chassis-mount power resistors designed to transfer heat into a suitable heatsink. Also known as aluminium housed or metal-clad resistors, they combine a compact enclosure with wirewound or film resistor technology for industrial power conversion and control equipment.

Aluminum housed resistor features

• Aluminum enclosure with a heatsink-mounting surface for efficient heat dissipation.
• Rated power options from 5 W to 500 W, depending on model and mounting conditions.
• Resistance values from 0.05 Ω to 100 kΩ.
• Resistance tolerances from ±1% to ±10%.
• Temperature coefficient options from ±10 ppm/°C to ±100 ppm/°C.
• Operating temperature range from -55°C to +275°C.
• Non-inductive construction is available for suitable resistance and power ratings.
