Through-hole resistors, also known as axial resistors, are among the most common components used in electronics circuits. CMF5549K900FHEB is a popular through-hole resistor used in applications such as radio frequency (RF) circuits, analog to digital (AD) circuits, and linear voltage regulator circuits.

Through-hole resistors are long cylindrical components, with two parallel leads extending from each end. The leads are bent 90 degrees at the end to form a shape known as a "shoulder". This shoulder allows the resistor to be soldered to the circuit board.

The CMF5549K900FHEB is a metal film resistor with a tolerable variation in resistance value of ± 5%. The body of the resistor is coated with a thin metal film, which determines the resistance value, and then covered with epoxy to protect from external stimuli.

The main application field of the CMF5549K900FHEB is low voltage, low current circuits and high reliability applications due to its low temperature coefficient of resistance, low noise voltage, and high accuracy. In particular, these resistors are well-suited for use in voltage divider circuits, such as the switched capacitor analog to digital converter.

The working principle of the CMF5549K900FHEB is fairly simple. The resistor is connected between two circuits, limiting the current flowing through it. The amount of current is proportional to the voltage applied, and thus the resistance value of the resistor. This principle can also be applied to other devices such as inductors, capacitors, and diodes.

The CMF5549K900FHEB is just one example of the many varieties of through-hole resistors available. These resistors are a reliable, cost-effective solution for many different applications. When selecting a through-hole resistor, it is important to consider the desired resistance range, and the environmental conditions that the resistor will face during operation.
