Through hole resistors, commonly referred to as THRs, are electrical components used to resist current in a circuit. These resistors are cylindrical and feature two or more pins or terminals, which allow them to be more easily mounted onto a circuit board via penetration of the pins through the holes contained therein. The pins of the THR provide both electrical and mechanical connections to the circuit board, which in turn provide the resistor’s primary purpose - to resist current in a circuit.

One such THR is the RN55E6491BR36. This resistor is an axial-lead type, meaning it is composed of a metal-film resistor encased in a cylindrical plastic body with its body pins extending in a coaxial fashion from the body. This resistor is composed of a cylindrical, colored body that reads 0.5 by 5mm and contains a white band (which indicates the tolerance value), along with a length of wire leads.

In terms of its application field, the RN55E6491BR36 is used in the production of printed circuit boards or PCBs. This is the most diverse and versatile type of resistor, which makes it suitable for a vast array of circuits in industries and applications. Additionally, this THR is certified to the European RoHS (Restriction of Hazardous Substances) standard, meaning that it is RoHS compliant and is made of materials that adhere to the regulations set forth by the European Commission.

In terms of working principle, this resistor works on the same principle as any other THR. When current is applied to the resistor via the leads, it creates resistance to the current by raising the temperature of the resistor’s body. The resistance creates a voltage drop, thereby reducing the amount of current through the circuit. The current (ampacity) and temperature (power rating) are two closely related factors that determine the present resistor.

The RN55E6491BR36 is a compact and reliable THR, and is suitable for a wide variety of circuits. Beyond its capacity to reduce current in a circuit, it is more than capable of maintaining its high current capacity even when exposed to sudden environmental changes. Additionally, its RoHS certification makes it a valuable component for the production of any PCB, due to its ability to meet the current European regulations and requirements for hazardous materials.
