Through Hole Resistors

Through hole resistors are a type of resistors designed to be mounted through holes in printed circuit boards (PCBs). The primary purpose of these resistors is to help control the current and voltage levels in electrical circuits. These resistors are commonly used in a variety of applications, from industrial to consumer electronics.

RN55D1872FBSL

The RN55D1872FBSL is a standard-sized through hole resistor, designed for surface-mount applications. The resistor has a resistance value of 1872 ohms, a steel-plated interior, and a nickel barrier on its exterior for improved reliability & durability. It features an operating temperature range of -55°C to 155°C & a power rating of 1/4W.

Application Field

The RN55D1872FBSL is a versatile component used in a variety of applications, ranging from industrial automation to consumer electronics. Because of its low resistance value, it is often used in circuits where precise current control is required. For example, it is often used in telecom circuits as a current-limiting resistor, or in power supplies as a protective device. Additionally, it is often used in audio systems to match the impedance of loudspeakers, and in switching power supplies to control inrush current.

Working Principle

Resistors work by creating an electrical opposition to the flow of current within a circuit. The resistance value of a resistor determines how much it will oppose current flow. For example, a resistor with a high resistance value will impede the flow of current more than a resistor with a lower resistance value. The RN55D1872FBSL’s resistance value is 1872 ohms, which makes it a good choice for applications where precise current control is desired. Additionally, its steel-plated interior and nickel barrier offer improved reliability and durability, even when placed in extreme temperatures.
