Through hole resistors are important devices used to control and limit the electrical current flow in electrical circuits. They come in a variety of shapes, sizes, and tolerance levels and are made from different materials depending on application and power requirements. The KNP1WSJT-52-3R is one such type of resistor, the characteristics of its application field and working principle will be discussed in this article.

The KNP1WSJT-52-3R through hole resistor is a high current, low resistance resistor with a power rating of 5watts and resistance values of 0.2~2.5 ohms. It is a low-cost, axial-lead resistor with 4 terminals and a wide operating temperature range of -55~+155°C. This type of resistor is suitable for crowded circuits and fast switching medium-high power applications. It is often used as current-limiting precision and current-equalizing resistors.

The KNP1WSJT-52-3R is a tubular cermet type resistor, made out of ceramic powder that has been blended with Nickel, Cobalt, and Titanium. This combination of materials creates a resistor that has a low temperature coefficient, a high heat resistance, low inductance, and excellent long-term stability. These properties make the KNP1WSJT-52-3R suitable for precision electronics and high reliability applications.

Work Principle - The KNP1WSJT-52-3R has a metal core with 4 terminals. When supplied with electricity, the current flows through the positive and negative terminals and heats up a special gel-filled ceramic container within the resistor. The heat of this ceramic container affects the material inside the resistor, resulting in a specific resistance value. The resistance value of the KNP1WSJT-52-3R is determined by the combination of materials it is made from and the internal structure of the resistor.

The KNP1WSJT-52-3R through hole resistor is widely used in electronic applications such as high current automotive payloads, load switching, and lighting. It is also used in limiting power supplies, in precision current regulators, and for pulse generators because of its low temperature coefficient of resistance, low inductance, and high power capability. Due to its low thermal coefficient of resistance, the KNP1WSJT-52-3R is also used in temperature control circuits.

Since the resistor is made from high-quality materials, it is capable of reliable operation for long-term periods and it is also resistant to corrosion. It has high surge resistance and low stray inductance, making it the ideal choice for high frequency applications. The KNP1WSJT-52-3R through hole resistor is also UL- and CSA-approved and is designed to meet military standards.

In conclusion, the KNP1WSJT-52-3R through hole resistor is a high-quality, high current, low resistance, and low inductance resistor suited for a variety of medium/high power applications. It is offered in a wide range of resistance values and is UL- and CSA-approved. Its excellent thermal shock resistance, long-term stability, and surge resistance make it ideal for applications in automotive payloads, load switching, lighting, temperature control circuits, power supply limiting, and precision current regulation.
