Through Hole Resistors

Through hole resistors mechanically attach two wire leads and enter the circuit board through a hole. These types of resistors are typically used in high power applications. The biggest advantage of using a through-hole resistor is the fact that it has a long life and remains relatively safe when exposed to extreme electrical or environmental conditions. This makes it an ideal choice for many applications.

FKN300JR-73-1R Application Field and Working Principle

The FKN300JR-73-1R through hole resistor is commonly used in both commercial and industrial applications. It is a high-performance, non-inductive resistor with low thermal EMF. The resistance range is from 0.5 ohm to 1 kilo ohm, and it can handle voltages of up to 600 volts. Its low thermal EMF allows it to be used in high power applications where the current needs to stay within tight tolerance window.

FKN300JR-73-1R is made from a thin film of nichrome that is deposited on a ceramic substrate. The nichrome film is sprayed onto the substrate to form the resistor element. The wire leads run from the ends of the resistor and are then soldered into the circuit board to complete the assembly. During operation, electricity passes through the resistor element, creating a tiny amount of heat. This heat dissipates through the ceramic substrate and is vented away to keep the resistor from burning out.

The FKN300JR-73-1R can handle high power applications with its high current rating. It is also well suited for high-frequency, pulsed applications, as it dissipates heat quickly and maintains its performance at high temperatures. Its low thermal EMF makes it an ideal choice for precision circuits, and it can be used in applications where higher losses would be unacceptable.

The FKN300JR-73-1R is highly reliable, cost-effective, and widely available. Its high tolerance for extreme temperatures makes it suitable for a wide range of demanding applications, and its durable design ensures long-term operation. As a result, this through-hole resistor is an excellent choice for high power applications.
