50 Watt 12 Ohm Aluminum Case Resistor with 5% Tolerance
Power: 50W
Resistance: 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: 5 pcs 50W 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.

Measured resistance was within 12 Ohms, +/- 5% . I was unable to verify 50W power dissipation claim, but it worked for my needs, which was at about 30W.

Used these for led turn signals on a jeep wrangler. No more bulb out warning on the dash or hyperflash

I bought these to use as input "pre charge" power limiter for DC to DC converters and inverters. I use them in conjunction with a timer circuit, they seem to work fine.

Nice load resistor for power supply projects. The terminals are very easy to connect wires with a pre-drilled hole in each terminal. The case has short fins for convection cooling. Case has tabs with pre-drilled holes for attaching the resistor to project case.
