Through Hole Resistors

Through Hole Resistors, sometimes called \'axial\' resistors due to the shape of their leads, are resistors that are designed to be inserted through a hole in a printed circuit board and then soldered on both sides. They are cylindrically shaped, with two leads extending from the body of the resistor and typically have resistances ranging from 0R (short circuit) to several megohm (MΩ) values.

The FKN5WSJR-73-1R2 is a through hole resistor and is part of a range of resistors from manufacturer FKN, Inc. The \'73-1R2\' section of the part number indicates that the resistor has a tolerance of +/-1% and a resistance value of 1.2 ohms. The 73-1R2 resistor is designed to be used in high current applications, typically up to 20 Amps continuous. The resistor\'s body is made from a high temperature, flame retardant, epoxy resin and the leads are made from tin plated copper.

In terms of its application field, the FKN5WSJR-73-1R2 is generally used to reduce the current flow in a given circuit. By inserting the resistor into the circuit, the current flow can be reduced or limited to the desired level. This is useful in a range of applications, from providing protection to high-power components in an electronic device to allowing the design of a complex circuit that uses a variety of current levels.

In terms of its working principle, the FKN5WSJR-73-1R2 works by providing resistance to the flow of current, thus reducing the amount of current that can flow through the resistor. This is known as Ohm\'s Law; the resistance, current and voltage in a given circuit are all related and one parameter can be derived from the other two. In the case of the FKN5WSJR-73-1R2, resistance (R) is known, so as an example, if the resistor is connected to a 9V power source, the current flowing through the resistor will be 9 divided by 1.2, or 7.5 Amps.

Finally, the FKN5WSJR-73-1R2 resistor is designed to operate at a temperature range of -65 to +155 degrees Celsius, and it should be noted that in applications using higher current levels, additional cooling may be required to prevent the resistor from overheating.

In conclusion, the FKN5WSJR-73-1R2 is a through hole resistor designed for high current applications up to 20 Amps. It works by providing resistance to the flow of current, allowing the current to be limited to the desired level. The resistor is also designed to work in a wide temperature range and additional cooling may be required in applications using higher power levels.
