Through Hole Resistors
The CMF55R49000GNEK is an example of one of the most common types of resistors, the through hole resistor.
Application Field
The CMF55R49000GNEK has many applications, such as current-limiting, overcurrent-protection, voltage-regulation, dampening and leveling. It is commonly used in point-of-load converters, post-regulators, DC/DC converters, voltage-regulating systems, and power-supply circuits. It can also be used in noise-suppression capacitors, frequency-dependent resistors and phase-shift networks.
The CMF55R49000GNEK is capable of providing precise, low resistances, while also having a wide operating temperature range and very low temperature coefficient of resistance. This makes it suitable for an extremely wide range of different applications.
The CMF55R49000GNEK is an ideal choice for applications where power-dissipation must be minimized due to space and heat constraints. It’s also frequently used in low-voltage and low-current applications, as it is capable of producing precise, repeatable results and is able to ensure excellent long-term reliability.
Working Principle
The CMF55R49000GNEK works by passing current through a conductive material, usually made of wire, which has been wound into a spiral shape. When the current is passed through the resistor\'s winding, a voltage is created across each coil. This voltage is directly related to the amount of current that is flowing through the resistor.
The resistance of the CMF55R49000GNEK is determined by the length of wire, the number of turns, and the materials used in the winding. The wires are usually made of thick metal such as copper or zinc. The number of turns determines the amount of resistance that the resistor will produce. The materials used in the winding are also important, because they can affect the resistance values. For example, if a resistor is wound with a copper wire of a certain length, it will produce a different resistance than if it is wound with a zinc wire of the same length.
When current is applied to the resistor, it produces a voltage across each turn of the winding. This can be measured with a multimeter, which is used to measure the resistors resistance. The resistance of a resistor decreases as the current increases. This means that when a higher voltage is applied to the resistor, it will produce a greater current.
The CMF55R49000GNEK is a reliable and consistent component, making it an ideal choice for a variety of applications. It can be used to create circuits with precise resistance values, increase voltage or current, dampen noise, or regulate the output of a power supply.
