About This Item
  • 50 Watt and 390 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.
  • In stock, ready to ship

Product Description:

50 Watt 390 Ohm Aluminum Case Resistor with 5% Tolerance

Power: 50W

Resistance: 390 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: 1 pcs 50W 390 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.
