Through-hole resistors are resistors that are designed to fit through printed circuit boards, also known as PCBs or Circuit cards. They are usually cylindrical and made from a conductive material, such as silver, aluminum, or tin oxide, and include two pins that go through the board. KNP3WSJB-73-0R18 is a type of through-hole resistor.

KNP3WSJB-73-0R18 is a three-pin metal-oxide film resistor. It has three pins, each with a diameter of 0.03 inch, and a body length of 0.18 inch. The resistor has a resistance of 3 W at 73 Ω and is rated for a temperature tolerance of 10%. It is designed for applications in the audio frequency range, and has good flameproof and vibration-proof properties.

The working principle of the KNP3WSJB-73-0R18 is based on an electric current generating heat around the resistor. The resistor is designed to dissipate the generated heat, limiting the current flow to within the operational limits of the device. The KNP3WSJB-73-0R18 is protected against overcurrents and overtemperature by using a positive temperature coefficient (PTC) element. This PTC element cuts out the current when the temperature exceeds a certain level, thus protecting the circuit from any damage.

KNP3WSJB-73-0R18 is suitable for many applications, particularly those that require both audio-frequency and voltages within the range. It is often used in electronic circuits and systems related to amplifiers, alarm systems, and embedded systems, as well as automation projects. It can also be used in medical equipment, automotive electronics, and power supplies. The KNP3WSJB-73-0R18 is also popularly used in consumer electronics, including TVs, radios, and computer systems.

The KNP3WSJB-73-0R18 offers superior performance in terms of stability and accuracy, while still being cost effective. Its high tolerance rating and good flameproof and vibration-proof properties make it ideal for use in general-purpose circuits and applications. With its small size, it is perfect for applications where space is limited. Overall, the KNP3WSJB-73-0R18 is a versatile and reliable through-hole resistor that provides consistent quality and performance.
