Through Hole Resistors may not be as common in modern technology as they were in the past, but your average CMF558K6900BEEB still has its uses. Here, we will explore the CMF558K6900BEEB’s application field and working principle.

Background

The CMF558K6900BEEB is a Through Hole Resistor, meaning it is a resistive component that is usually installed by soldering its legs into the circuit board opening. Because of its through-hole mounted nature, this component has been largely replaced by its surface mount counterpart in modern electronic circuit design.

The CMF558K6900BEEB’s typical rating is 5W, 12V, 200K ohm1 . The resistor has 4 terminals, each of which are soldered directly into the circuit board. This increase the overall rigidity of the resistor, allowing it to carry load better without bending. The most profound feature of this resistor is its high tolerance value. It has a tolerance of 5%, which is nearly double the tolerance value of its surface mount counterparts. This gives it greater application in critical electric circuits such as radios and amplifiers.

Application Fields

The most applicable field of the CMF558K6900BEEB is in the radio and audio electronics. The resistor’s highly accurate rating allows it to be used in the electromagnetics of devices such as radios and amplifiers. Its ability to bear larger amounts of voltage helps as well.

The CMF558K6900BEEB is also commonly used in industrial and automotive applications. As previously mentioned, the resistor is highly durable, taking a beating from the environment much better than its surface mount counterparts. This makes it suitable in environments such as industrial circuit boards which are exposed to fluids or high temperatures. Automobile electronics also benefit from the resistor’s durability.

Working Principle

The CMF558K6900BEEB works in accordance with the Ohm’s law. This law states that electricity running through a conductor is inversely proportional to the resistance of the conductor. The CMF558K6900BEEB’s resistance, in this case, is 200K ohm1. As electricity passes through the resistor, it is reduced to match the resistor’s resistance.

The CMF558K6900BEEB also acts as a fuse. The fuse present in these resistors is designed to blow in the event of too much current passing through. The resistor’s high tolerance enables it to bear higher voltage ratings than its surface mount counterparts. This further enhances its application range.

Conclusion

In conclusion, the CMF558K6900BEEB is a Through Hole Resistor with applications spanning the radio and audio electronics, industrial and automotive industries. Its ability to bear higher voltage and its increased tolerance rating make it more reliable for use in such fields. To work, the resistor follows Ohm’s law, showing that electricity passing through the resistor is inversely proportional to its resistance. It also serves as a fuse, blowing up if too much current is present.
