KNP100JR-52-12R Resistors

Through Hole Resistors

Through Hole Resistors, commonly referred to as THRs, are resistors that are designed to be soldered into a printed circuit board (PCB). This type of resistor is most often used in high-frequency applications where components must be connected to the board through a hole drilled into the PCB. The KNP100JR-52-12R is a THR specifically designed for high-frequency applications, and is commonly used for signal conditioning, RF-amplitude control and many other applications.

KNP100JR-52-12R Application Field and Working Principle

The KNP100JR-52-12R THR is designed for general purpose signal conditioning, high-frequency circuit designs, and RF-amplitude control. The resistor is specifically designed to suppress EMI/RFI noise while attenuating transient signals. This is accomplished by using a reduced lead length, thus limiting the amount of inductance of lead within the resistor’s path. The short lead length coupled with low parasitics ensures low line loss, as well as higher power handling. The resistor also features low-capacitive parasitics, which helps maintain a low-impedance at high frequencies.

In order to use the KNP100JR-52-12R effectively, the user must understand the working principle of the resistor. The resistor works by using a combination of resistive elements and inductor windings. The resistive element is connected in series to the inductor. As current passes through the resistor, its resistance decreases, resulting in a decrease in voltage drop across the resistor. This causes the inductor to react against the current to increase voltage drop across itself. By controlling the resistance and inductance of the resistor, the circuit is able to maintain the same voltage level across the resistor and the inductor, regardless of the impedance of the load.

Conclusion

The KNP100JR-52-12R THR is an ideal choice for a variety of high-frequency applications. It is designed to resist EMI/RFI noise and attenuate transient signals while providing low line loss. Its low-capacitive parasitics help maintain a low-impedance at high frequencies, and its short lead length ensures higher power handling. By understanding the working principle of the resistor, users can effectively use the KNP100JR-52-12R in any of their high-frequency applications.
