Through Hole Resistors

Through hole resistors are a type of electrical resistor built with conventional leaded construction instead of surface mount technology, and typically consist of a cylindrical body made of ceramic, metal, or plastic with two printed metal terminals extending from it. The most common and recognizable type of resistor is the carbon composition resistor, which is most often used to limit current or voltage in low power circuits. These resistors are used in a variety of industries and applications, ranging from consumer electronics to automotive, industrial, and military applications.

CMF558K6600FEBF Application Field and Working Principle

The CMF558K6600FEBF through hole resistor is a two terminal, non-inductive, fixed-value current limiting component. It is commonly used in a wide variety of consumer electronics, automotive, industrial, and military applications which require a fixed resistor with a maximum power rating of up to 5 Watts. The device is soldered directly to a PCB and has a tolerance of 5% at 20 degrees Celsius.

The device consists of a ceramic body filled with metal flakes and functions by dissipating energy in the form of heat. When a voltage is applied across the terminals, resistance to the flow of electrical current is created within the device. This resistance is proportional to the amount of voltage applied, and is usually designated by a color code determining the tolerance of the resistor. The heat generated by the resistor is dissipated through the metal lead frames, reducing the internal temperature of the resistor and preventing damage.

The CMF558K6600FEBF is generally used to limit voltage in order to prevent damage to connected components. Additionally, the resistor can be paralleled with other resistors to increase the power limitation level, or be used in series with fuses or other components to provide overvoltage protection. In automotive electronics, the device is typically used to limit current in windshield and other lighting circuits, protecting them from voltage transients and electrical noise caused by the vehicle’s alternator.

The CMF558K6600FEBF is a reliable, cost-effective through-hole resistor that is easy to apply in compact designs. It is widely available in a range of voltage and power ratings, and also features a wide operating temperature range, making it suitable for a variety of applications. This makes it an excellent choice for custom designs requiring a reliable, low-cost resistor.
