Through Hole Resistors are widely used electronic components in circuit designs. CMF554K4800DHBF is a through hole resistor and is primarily used to limit or regulate current flow and voltage levels. They offer resistance to direct current (DC) and many alternating current (AC) electrical signals.

The CMF554K4800DHBF is a 4.80K ohm resistor with a maximum power rating of 1/8 watt and a tolerance of ±5%. It is a 0402 size resistor, which means it features a 0.04” x 0.02” rectangular shape and a 0.040” diameter lead spacing. It is a metal film resistor with a flame retardant coating material, making it suitable for automotive applications, medical systems, and other electronics applications.

The resistor is rated for use in temperatures between -55° C and +150° C. It has a maximum DC current rating of 250 mA and maximum reverse voltage rating of 100 V. The operating frequency range is from 0 Hz to 5 MHz. CMF554K4800DHBF has a temperature coefficient of ±100 ppm/°C, this means that its resistance is affected by changes in the operating environment.

The resistor is designed for through-hole mounting and features a nickel-barrier plating on its two leads to avoid corrosion. Due to its very small size, it can be soldered on tiny spaces and then secured using an epoxy coating. It has a standard 5-lead form which makes it easily mountable.

The working principle behind CMF554K4800DHBF is the same as any other resistor. Its resistance limits the current flow through it. When electric current passes through the resistor, energy is lost in the form of heat. The heat produced is dependent on the amount of current and the resistance. This heat must be dissipated from the resistor, or it will eventually fail. Heat sinks or air circulation can be used for heat dissipation.

In summary, the CMF554K4800DHBF is a through hole resistor most commonly used in automotive, medical, and many other electronic applications. It has a high power rating and is designed for high temperature use. The working principle behind this small resistor is the same as any other, it limits the current flow by producing heat which must then be dissipated.
