Through Hole Resistors are components which are commonly used in electrical and electronic applications to regulate the current flow. The RNR55H4642FPB14 is a through hole resistor of a type known as metal oxide film (MOF) and uses a resistor element made of aluminum oxide. It is a non-inductive type resistor, meaning it has a low susceptibility to inductance-induced voltage spikes, making it ideal for precision and safety-critical applications. The resistor\'s high power capability and low temperature coefficient make it well-suited for use in a variety of environments, from deep-sea exploration to aerospace engineering.

The RNR55H4642FPB14 has an operating range of -55°C to +175°C, and its resistance value falls between 2.5 ohms and 250 kiloohms. It also possesses a high power handling capacity, with a power dissipation rating of 0.2 watts to 2.2 watts. The resistor is Class B flame retardant, making it suitable for a wide range of industrial applications. The part is also RoHS compliant, meeting all the applicable safety requirements.

The RNR55H4642FPB14 is a through hole resistor which works through a number of different principles. Its main operation is based on the phenomenon of ohmic heating, which is what happens when electricity flows through a material. As electrical current passes through the resistor, it heats up the metal oxide film material and the resistor itself, causing the resistance to increase or decrease depending on the material\'s temperature coefficient. The resistor also employs resistive strain gaging, which is the measurement of resistive changes resulting from physical forces being applied to the resistor. Additionally, the RNR55H4642FPB14 also tends to employ positive temperature coefficient (PTC) to further protect against voltage spikes and surges.

The RNR55H4642FPB14 is an exceptionally versatile through hole resistor, designed to withstand temperatures up to 175°C, and its range of power dissipation (from 0.2 watts to 2.2 watts) makes it suitable for a variety of industries, including electrical, consumer electronics, automotive, and aerospace applications. Its high resistance value, low temperature coefficient, flame retardance, and RoHS compliance make it an ideal choice for many high-precision, high-safety solutions.
