Product Overview
Dale RH-50 wirewound resistor marked 120Ω and 50W. This chassis-mount power resistor uses a gold anodized aluminum housing designed to transfer heat into a mounting surface for proper dissipation. The RH-50 is part of Dale’s high-power RH series commonly used in industrial controls, power supplies, and load applications.
The 50 watt rating applies when mounted to an appropriate heatsink or metal chassis. Wirewound construction provides stable resistance under sustained load and is typical for high-power fixed resistor designs.

Frequently Asked Questions
Is the full 50W rating usable without a heatsink?
The 50 watt rating applies when properly mounted to a suitable heatsink or metal chassis. Free-air dissipation is significantly lower.
What does the handwritten “120.5” indicate?
The marking appears to be a handwritten measured resistance value. The nominal resistance marking is 120 ohms.
Are the terminals in good shape?
Terminals are intact and show no visible corrosion or damage.
Is this resistor inductive?
Standard RH-series wirewound resistors have inherent inductance typical of wirewound construction.
Do you have multiple available?
Available quantity reflects current inventory on hand.
Built to shed heat and handle load. Mounted properly, it remains a dependable workhorse for high-power circuits.
