What resistor can 25w12 JF cement resistor be replaced?

The cement resistor can be replaced with a ceramic electric or carbon film resistor razor, but the power of the carbon film resistor is too small, so it is best to replace it with a ceramic resistor.

The cement resistor is made by winding the resistance wire on the non-alkaline heat-resistant porcelain, and adding heat-resistant, moisture-resistant and corrosion-resistant materials to protect and fix it, and put the winding resistor body into the square porcelain frame, and fill and seal it with special non-combustible heat-resistant cement. The outer side of the cement resistor is mainly made of ceramic (generally divided into high-alumina porcelain and feldspar porcelain).

Cement resistance. Cement resistor, literally is a resistor encapsulated with cement, in fact, the material of the canning is not traditional cement, but an insulating silicide. The resistance wire is wound on the non-alkaline heat-resistant porcelain, and the heat-resistant, moisture-resistant and corrosion-resistant materials are added to protect and fix it, and the wire-wound resistive body is put into a square porcelain frame, and it is filled and sealed with special non-flammable heat-resistant silicide resistance cement.

There are two types of cement resistors: ordinary cement resistors and cement wirewound resistors.

In this regard, as long as you choose 15 watts to 10 12 ohms, it can be completely replaced, and the effect is better.

Because the resistance value of this resistance is relatively small, only 12, and the power is relatively large, you can use a section of electric furnace wire (a few hundred watts of electric furnace wire is the best, do not have too much power of electric furnace wire, it is not easy to make.) Wrap around a suitable electronic component, measure it with a multimeter over and over again, and you're good to go.

It can be replaced with its original electronics, but this resistor is a little more expensive.

If you want to replace it, find a resistor with the same resistance. The same 12 ohm resistor can be replaced.

Generally speaking, I think that if you have a cement resistor like this one, you can directly replace it with another resistor.

In fact, as long as the power supply is turned on, it can be guaranteed to be stable.

25 watts of 12 ohm GF cement. The resistor can be replaced by any resistor, as long as it is 25 watts, a resistor of 12 ohms can be replaced.

The 25 watt 12 ohm gif cement resistor can be used in any store**, and the aluminum resistor can be used.

What does cement resistance 10w47kv mean Hello dear, 10w refers to the power generated on the resistor, the maximum can not exceed this value, otherwise the resistance may burn out. Hope it helps. If my answer is helpful to you, please also give a thumbs up (comment in the lower left corner), look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress.

Finally, I wish you good health and a good mood!

Cement resistance is the resistance that is potted with cement (in fact, it is not cement but refractory mud, which is commonly known);

Cement resistors are all resistors with higher power. It is able to allow the passage of large currents.

First of all, you need to know how much current is through this resistance and how big this resistance is, and then multiply the square of the current by the resistance value to be the actual power consumed by this resistor.

For example, the resistance value of this resistor is 100, and the current passing through it is 300mA, then the power consumed by this resistor is, then the power should be at least 10W resistance when selecting the resistor.
