Through Hole Resistors

Through-hole resistors are electrical components that feature a resistance element enclosed in a cylindrical body with leads protruding from either end. They are commonly found in electronics circuit applications for providing current limiting, voltage switching, and bias power stability in the electrical signal path. The CMF552M4000FHEA is one such device and its application fields and working principle will be discussed in this article.

Application Field of CMF552M4000FHEA

The CMF552M4000FHEA is a through-hole resistor that is mainly used as a strain relief device in circuitry where live, electric wires coming out of the circuit board may be subject to physical stress. It is extremely useful in tightly-packed circuits and components, such as in medical devices or aircraft components, which are becoming increasingly miniaturized. Other typical applications include attenuation circuits, precision current-monitoring circuits, and surge protectors.

Working of CMF552M4000FHEA

The CMF552M4000FHEA consists of a resistance element (resistor) surrounded by an integral cylindrical body. It is designed to be soldered directly into the circuit board, thus making it an “in-line” resistor. The leads of the resistor are then soldered to the circuit connections for the desired resistance value. When current is introduced by the circuit, it will flow through the resistor (which has a certain resistance value) and the voltage drop across the resistor will be proportional to the resistance of the resistor.

The CMF552M4000FHEA also offers excellent protection against physical vibrations due to the use of its integral cylindrical body, which prevents the conductors of the resistor from becoming loose and causing shorts. This is of particular importance for precision current measurement circuits as it ensures a stable, accurate current flow.

In summary, the CMF552M4000FHEA through-hole resistor is an extremely useful device with numerous applications in electronics circuits, particularly when precision current-monitoring & surge protection are required. It offers physical protection against vibrations and its highly-integral design make it perfect for use in tightly-packed circuits and components.
