Cement resistor, as the name suggests, is a resistor sealed with cement (actually not cement but refractory mud, which is commonly known). The resistor wire is wound around a non alkaline heat-resistant ceramic piece, protected and fixed with heat-resistant, moisture resistant and corrosion-resistant materials, and the wire wound resistor body is placed in a square porcelain frame, filled and sealed with special non combustible heat-resistant cement. There are two types of cement resistors: ordinary cement resistors and cement wire wound resistors. The appearance of the cement resistor is shown in the diagram.

Civilian frequency dividers generally use cement resistors of several watts; In order to meet the requirements of special occasions, professional frequency dividers generally use 10W, 20W, 30W, or even 50W to 100W; This is not surprising, after all, a few watts of power is clearly not enough in professional performance settings. Some friends' frequency dividers often have broken resistors, which are generally caused by low power. When replacing them, you can choose a slightly higher power, such as the original 10W. If the installation space allows, you can replace it with a 20W one without any side effects; However, it should not be too large to avoid posing a threat to the speaker!

Features:

^{Cement resistor is a type of wire wound resistor, which belongs to high-power resistors and can allow larger currents to pass through. Its function is the same as that of a general resistor, but it can be used in situations with high current, such as being connected in series with an electric motor to limit the starting current of the motor. The resistance value is generally not large. Cement resistors have the characteristics of small size, shock resistance, moisture resistance, heat resistance, good heat dissipation, and low price, and are widely used in power adapters, audio equipment, audio dividers, instruments, meters, televisions, automobiles, and other equipment.}

Application:

^{In addition to current limiting, cement resistors have various other uses. For example, when the high pitched sound of a speaker is too loud, a resistor of only about 4 ohms is connected to the positive pole of the high pitched sound, and then a resistor of about 20 ohms is added. This reduces the sensitivity of the high pitched sound by about 3-4dB. This relationship is that the smaller the resistance value of the string, the less the sensitivity will decrease, and the larger the resistance value of the string, the more the sensitivity will decrease; The resistance of the parallel is opposite to that of the string, that is, the larger the resistance of the parallel, the less it decreases, and the smaller it decreases, the more it decreases. Be careful not to exceed the limit. Generally, the resistance of the string is below 20 ohms, and the resistance of the parallel is above 4.7 ohms, so as not to affect the listening effect!}
