What is its use? Has anyone used it or knows about it? . . .

Precision resistor?

The yellow part you see is the aluminum heat sink, and the resistor body is inside it. Since the resistor has a heat sink outside, it is obviously used in places where the power dissipation is quite large.

Has it been useful?

Probably not, precision resistor

An aluminum heat sink is added outside. It should be a resistor with relatively high power. The heat sink is used when the heat is relatively large. In addition, ordinary resistors will not have heat sinks even if the heat dissipation is relatively large. The addition of heat sinks indicates that the temperature requirements are relatively high.

It is probably the load resistance, which is absorptive and dissipates the energy.

High-power aluminum shell resistors seem to have a purpose for motor braking. They can be used as loads or as dummy loads for testing.

Motor brake, but no specific introduction

It is mostly used to kill cars with high-power motors.

Thank you, I'll go check it out

Load resistance, use 4-8 ohm resistance as load when testing the power amplifier.

It's been useful, I saved it, thank you for your selfless sharing

The shell is added 1) for heat dissipation 2) explosion-proof. It is generally used to test power, such as in the e-cigarette industry.

It is used for power absorption, load simulation, etc., as mentioned by many netizens above.

I have used this resistor before. There was a lithium battery charging and discharging maintenance cabinet product that used this resistor as a lithium battery discharge load. Or it can be used to test the output power of the switching power supply and aging experiments.
