50 Watt 40 Ohm Aluminum Case Resistor with 5% TolerancePower: 50WResistance: 40 ohmTolerance: 5%Connection Type: RodsBoard Length: 49.8mmMounting Hole Diameter: 3.5mmDistance Between Mounting Hole: 41mmMaterials: Nickel Alloys Wire Wound Resistor with Aluminum CaseColor: GreenPackage Content: 2 pcs 50W 40 ohm Aluminum ResistorSuggestion: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, 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.
