Description
50 Watt and 4.7K 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. 50 Watt 4.7K Ohm Aluminum Case Resistor with 5% Tolerance Power: 50W Resistance: 4.7K ohm Tolerance: 5% Connection Type: Rods Board Length: 49.8mm Mounting Hole Diameter: 3.5mm Distance Between Mounting Hole: 41mm Materials: Nickel Alloys Wire Wound Resistor with Aluminum Case Color: Gold Package Content: 2 pcs 50W 4.7K ohm Aluminum Resistor Suggestion: 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.
