Specification Brand : uxcell BulletPoint1 : 5 Wattage and 50 Ohm, 5% tolerance. Wire Wound Resistor owns high stability and accuracy. Moreover, it was used for various application because of the wide resistance range. BulletPoint2 : Aluminum Housed. An insulated cover on the wounded wires would block out the heat, which promises the high performance of a resistor. Hence, the cooling job was achieved by aluminum case. BulletPoint3 : This 5W resistor formed with qualified copper, nickel, and aluminum. With the compact structure and heat dissipation design, a capability of overload has been built. BulletPoint4 : Board length 3/4 inches(19mm) and two wires for a connection. BulletPoint5 : 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. Color : One Color CustomerPackageType : Standard Packaging ExternallyAssignedProductIdentifier1 : 0778739187254 ExternallyAssignedProductIdentifier2 : 778739187254 ExternallyAssignedProductIdentifier3 : 00608641811889 IncludedComponents : 20 x Carbon Film Resistors ItemName : uxcell 2 Pcs Aluminum Case Resistor 5W 50 Ohm Wirewound for LED Replacement Converter 5W50RJ ItemPackageDimensions_Height : 12.7 centimeters ItemPackageDimensions_Length : 3.302 centimeters ItemPackageDimensions_Width : 8.7884 centimeters ItemPackageQuantity : 2 ItemTypeKeyword : single-resistors Manufacturer : uxcell Material : Aluminum Material1 : Cermet Material2 : Wirewound ModelNumber : a18032800ux0018 NumberOfItems : 1 PartNumber : a18032800ux0018 ProductDescription : Main Body Length: 1.9 cm/ 0.75 inches Power: 5 Wattage Rated Resistance: 50 R Tolerances: 5%(J) Connection Type: Wires Wires Length: 23mm/0.9 inches Weight(Single): 4g/0.15 Oz Materials: Nickel alloys Wire Wound Resistor with Aluminum Case Color: Gold
