Through Hole Resistors

A through hole resistor is an electronic component that produces electrical resistance in a circuit. Through hole resistors are designed to be inserted into plated through holes on printed circuit boards (PCB) and thus, also referred to as through hole mount components.

KNP5WSJB-73-240R application field and working principle

KNP5WSJB-73-240R is a through hole resistor typically used in power supplies and lighting applications. It features low power dissipation, high overload capacity, small size, and good temperature stability.

The KNP5WSJB-73-240R has a five-watt power rating and can operate within -55-125 degrees Celsius temperature range with a temperature coefficient of +/-3.5ppm/degree Celsius. This ensures that it produces stable electrical resistances across a wide temperature range.

The KNP5WSJB-73-240R resistor also has a small size with a diameter of 5mm and a length of 7mm. This makes it easy to work with on tight printed circuit boards, and it also helps in preventing accidental contact of the components. The small size also allows the component to fit in a variety of applications that require space saving, like cell phone circuitry.

With its high overload capacity, the resistor is highly resistant to voltage and current overloads up to a certain limit. This ensures that the resistor does not suffer damage when subjected to a sudden rise in power or voltage.

The resistor has a low power dissipation, which means that it does not produce a lot of heat. This helps in keeping the temperature of the power environment stable, reducing operational costs, and increasing the efficiency of the power supplies.

The KNP5WSJB-73-240R resistor works on the principle of ohm\'s law, which states that the current flowing through a resistor is inversely proportional to its resistance. This means that the resistance of the resistor determines the amount of current that can flow through it.

To summarize, the KNP5WSJB-73-240R is a through hole resistor typically used in power supplies and lighting applications. It features low power dissipation, high overload capacity, small size, and good temperature stability, making it a perfect choice for applications that require a reliable high-power component.
