Green 4 Ohm 5% 100 Watt Aluminum Shell Wire Wound Resistor 2pcs

Aluminum housing for heat dissipation, suitable for cooling plate installation. Small size, high power load, standard and non-inductive winding types. High insulating capacity, good performance in vibration. Multiple connection modes, easy to install. Widely used in power supply, transducer, elevator and high requirement equipment industry.

Suggestion:

a. The load resistor will get huge hot, please don't touch it when the resistor is working. Because aluminum resistor is a braking device which transfers Electric energy to Thermal energy. This is a normal physical phenomenon.

b. The load resistor should be mounted on metal board

c. We recommend a 30%-50% increase in rated power based on your actual load power and add a heat sink device when it is necessary.
If you choose a 30% increase in rated power, you must add a heat sink device.
If you choose a 50% increase in rated power, you can add a heat sink device for the best use of its performance.
d. Not recommend to use it for Automotive repair or refit unless you have professional knowledge.
