Through Hole Resistors

Through hole resistors are resistors which have leads that are designed to fit through a hole drilled in a printed circuit board (PCB). These leads are soldered into the PCB to form permanent connections, thus making them ideal for high power applications. The size of the resistor and the length of the leads can vary depending on the application.

CA51003R000KR05 application field and working principle

The CA51003R000KR05 is a through-hole resistor designed for use in high-power, high-voltage applications. Its features include low power consumption, high temperature tolerance, excellent long-term reliability, and a wide operating temperature range. The resistor is built using two-layer ceramic substrate technology, which gives it a low parasitic inductance. It also includes a Nichrome resistor element, allowing it to maintain a very exact resistance value over a wide range of temperatures. The resistor also features an internal resistance value adjustment mechanism, allowing for further tuning of the device for specific applications.

The CA51003R000KR05 is mainly used in applications such as surge protection, electrical noise suppression, input and output filtering, and as reference resistors. It is especially useful in applications where transient loads and high-frequency signals may be present. In these cases, the CA51003R000KR05’s low parasitic inductance helps to reduce high-frequency noise and provides better stability over temperature and supply voltage variations.

This resistor is also used in applications where exact resistance values are required. For example, this resistor is ideal for calibrating voltage dividers, measuring DC current, and creating digital to analog converters. The wide operating temperature range and high accuracy of this device makes it an ideal choice for such applications.

The working principle of the CA51003R000KR05 is relatively straightforward. When the device is connected to a voltage source, current flows through the resistor element and its respective leads. As the current flows, some of the energy from the voltage source is converted into heat, which causes a change in the resistance value of the resistor. This change is proportional to the total amount of current that has been applied, thus allowing for precise control of the device.

In addition to its accuracy and durability, the CA51003R000KR05 is also a cost-effective solution when compared to other through-hole resistor solutions. As such, it is often a preferred option for applications that require reliable, accurate resistors.
