50W 3.9 Ohm 5% Aluminum Housing Resistor Screw Tap Chassis Mounted Aluminum Case Wirewound Resistor Load Resistors Green 2 pcs

Key Features

• 50 Watt and 3.9 Ohm, 5% tolerance. Wire Wound Resistor owns high stability and accuracy. Moreover, it was used for various application because of the wide resistance range.
• Aluminum Housed. An insulated cover on the wounded wires would suppress the heat, which promises the high performance of a resistor. Hence, the cooling job was achieved by aluminum case.
• This 50W resistor formed with qualified copper, nickel, and aluminum. With the compact structure and heat dissipation design, a capability of overload has been built.
• Board length 1.96 inches(49.8mm) with two 3.5mm mounting hole, and 2 terminals for a connection.
• Reliable. Problems like the flush LED would have a perfect solution, or you can use it in any AC DC circuits, converter, inverter, motor speed control, drivers, etc.

Package Content

2 pcs 50W 3.9 ohm Aluminum ResistorSuggestion:a. The load resistor will get huge hot, please don't touch it when the resistor is working.Because alumnium 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, not on flammable board such as plastic board,rubber,paper,wood and etc. 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.
