Through Hole Resistors (THR), also known as wire wound resistors, are a type of resistor that are usually used in circuit boards due to their robust construction and high power handling. The FKN2WSJR-73-2R is a relatively new THR from a Japanese manufacturer Kaga, and it has become increasingly popular for its good performance and wide range of application fields.

This type of THR has two distinguishing features: its ability to handle a wide range of temperature extremes and its low electro-magnetic interference (EMI) or stray capacitance. The FKN2WSJR-73-2R is specifically designed for use over -55℃ to +150℃, making it suitable for use in model trains, aircraft, and automotive applications, as well as industrial and domestic circuits.

In addition to its temperature range, the FKN2WSJR-73-2R also has a low EMI value of 2.2pF compared to the average 6pF of other THR resistors. This makes it an ideal choice for designs that require reduced EMI levels or that are sensitive to EMI (such as medical equipment and communications systems). Additionally, this resistor is reliable and robust enough to provide a long lifetime of stable operation even in harsh environments.

The construction of the FKN2WSJR-73-2R is what makes it so effective. The resistor features a metal-glass alumina composite structure that is designed to withstand temperature extremes while keeping its EMI level low. This construction also makes the THR highly resistant to vibration and shocks, and the resistance element is made of a high-quality alloy that provides a long lifetime of stable operation.

The FKN2WSJR-73-2R also features a working principle which ensures a linear temperature coefficient of resistance. This means that it’s able to track temperatures over its operating range without compromising on its underlying power by significantly increasing its temperature coefficient. This helps to maintain a steady current and provides greater consistency in operating conditions.

In addition to its consistent power and temperature coefficient, the FKN2WSJR-73-2R also offers good environmental protection. The resistor is insulated with a durable powder paint finish, which prevents oxidization and corrosion. This helps to ensure that the resistor can handle high temperature conditions while providing reliable performance.

The FKN2WSJR-73-2R is an impressive THR resistor that offers a wide range of applications and excellent performance. Its robust construction and reliable performance in extreme temperatures make it an ideal choice for both consumer and industrial applications. Additionally, its low EMI value and linear temperature coefficient make it suitable for a wide range of applications, including model trains and medical equipment.
