Through Hole Resistors

Often abbreviated as TH, through-hole resistors are resistors with two leads inserted through a cylindrical hole in a board or component called a through-hole. Widely used over the decades, through-hole resistors were a common part used in constructing circuit boards until they began to be replaced in the 21st century by surface-mount components.

When it comes to RNX05047M5FKR6, this TH resistor is surface-mount type chip resistors which features small size and lightweight, high operating temperature range up to +125°C. Additionally, they have excellent high voltage performance, with an increased power rating for extreme operation conditions.

Application Field

Due to its small size and high voltage performance, RNX05047M5FKR6 are commonly applied in various applications, such as consumer electronics, automotive systems, computer systems, networking communication, measuring and industrial control systems, and power control and management.

Specifically, it is mainly used as an armature, drive, engine, starter, field effect transistor (FET), thyristor, integrated circuit (IC), and potentiometer. In consumer electronics, it can be used to regulate the input/output current of a device, reduce noise and improve the product reliability.

Working Principle

RNX05047M5FKR6 works by using Ohm\'s law, which states that current is proportional to voltage while resistance is constant. When voltage is applied to the two leads of the resistor, current flows through the circuit. The amount of current depends on the applied voltage as well as the resistance value. As the applied voltage increases, the current also increases, and vice versa.

At any given time, the amount of current flowing through the resistor will be equal to the applied voltage divided by the resistance value of the resistor. This means that the higher the resistance value of the resistor, the lower the current will be, and vice versa. Since there are no moving parts in a through-hole resistor, it provides a reliable, constant resistance value over time.
