Through Hole Resistors

Through-hole resistors are an essential component used in almost all electronic circuits. The CMF55442R00BEEA70 is a through-hole resistor, and its application and working principle are as follows.

Application

CMF55442R00BEEA70 is an axial leaded, non-inductive long-term tolerant and non-conductive type resistor. It can be used in a diverse range of applications which require high tolerance and stability, such as:

• High-power audio amplifiers
• Low noise voltage regulators
• High frequency radio circuits
• Space research projects
• Computer controlled electronic processes

As it is a through-hole component, it is also well suited for applications where wires are prone to vibration. CMF55442R00BEEA70 comes with power ratings up to 3 W and an operating temperature range of -55°C to +150°C. It is available in various tolerance values, including 0.1%, 0.25%, 0.5%, 1%, and 2%, as well as a range of resistance values.

Working Principle

CMF55442R00BEEA70 works on the principle of organic semiconductors, which forms a resistive barrier between two electrical contacts. This barrier inhibits current from flowing between the contacts, and the degree of resistance depends on how much current can be allowed to pass.When a voltage is applied to the terminals of the resistor, electrons from the negative terminal flow into the positive terminal. As they pass through the resistor, their energy is dissipated in the form of heat. This heat is the main source of energy loss in the resistor. The total amount of energy lost depends on the resistance value of the resistor itself and the amount of current flowing through it.The CMF55442R00BEEA70 has a maximum power rating of 3 W and is extremely tolerant of mechanical force, making it suitable for applications such as high-power audio amplifiers and space research projects. Its long-term stability and non-inductance characteristics make it ideal for use in low noise voltage regulators and computer-controlled electronic processes.

Conclusion

CMF55442R00BEEA70 is a through-hole resistors with an application field in a diverse range of industries, from audio amplifiers to space research. It has a maximum power rating of 3W and an operating temperature range of -55°C to +150°C. Its organic semiconductors technology provides it with non-inductance and long-term stability characteristics, making it ideal for low-noise voltage regulator circuits and high-frequency radio applications.
