Through-hole resistors are passive electronic components that are made up of a number of resistive elements that are arranged and connected to each other in a specific manner. They are primarily used to provide resistance to a current that is passed through them, and are among the most commonly used passive electronic components in the industry today. As such, most modern electronic circuits include resistors in order to create desired electrical characteristics.The RNR55H4993FRB14 is a through-hole resistor that is typically used in a wide range of applications. This include applications such as power supply filtering, voltage adjustment, current flow limitation, and signal conditioning. In order to understand the working principle of this component, it is important to first gain an understanding of resistors, and the theory behind electronic resistors.Resistors are passive electronic components which are used to control electrical current in electronic circuits. Resistance is a measure of the circuit\'s opposition to current flow, and is measured in ohms. When a current passes through a resistor, a voltage drop occurs across the resistor which causes a reduction in the electrical energy being supplied. This resistance is determined by the resistor\'s specific physical characteristics such as its resistance material, its size, its shape, and the distance between its two ends.The RNR55H4993FRB14 is composed of two 4-terminal resistive elements with a combined total resistance of 55 ohms. The resistances of each element is determined by the dimensions of the resistor, as well as the material it is made of. It is also made with a robust epoxy coating capable of withstanding high temperatures and vibration. This resistor exhibits a high tolerance of up to ±100ppm over its operating temperature range of -55°C to +225°C.In terms of performance, the RNR55H4993FRB14 exhibits excellent temperature cycling, and has an extremely low temperature coefficient of -0.00147K/K. This ensures that any changes in the ambient temperature will not affect the resistor\'s desired electrical characteristics. In addition, this component also boasts excellent noise rejection and EMI characteristics, as well as low inductance.The working of this component is relatively straightforward. Whenever an electrical current passes through the component, a voltage drop occurs across the resistive elements. This voltage drop is equal to the current multiplied by the total resistance of the resistor. This force limits the flow of electric current and helps to create the desired electrical behavior in the circuit.In conclusion, the RNR55H4993FRB14 is a robust, reliable and highly versatile resistor that can be used in a wide range of applications. It is specifically designed to resist shock and vibration, and is able to maintain its desired electrical characteristics even in the most extreme temperature and vibration conditions. Furthermore, due to its low temperature coefficient, the component is also able to operate continuously through temperature changes, and is able to successfully reject any noise and EMI interference that may occur in the circuit.
