Through Hole Resistors

Through hole resistors are a type of resistor closely resembling the resistor lead type, with the distinction that a through hole resistor is usually an axial lead type, with two or more leads protruding from the body of the resistor and inserted in holes on a printed circuit board. A resistor is a small electrically-conductive device that is used to reduce the flow of current in a circuit, and the through hole resistor is a particular type of resistor with the features of having two or more leads which are inserted into holes on the printed circuit boards.The PF2203-1R8F1 is a type of through hole resistor, with a resistance value of 1.8 ohms and a power rating of 0.23 watts. It is manufactured with an axial lead style, and the leads are made of nickel-plated copper, which has a low electrical resistance and is highly corrosion-resistant. The resistor itself is contained in a moulded plastic (epoxy) body, and is usually used for applications requiring a large number of resistors in a short amount of time.The case size of the PF2203-1R8F1 is 2.0 x 6.3 mm, and the height of the resistor is 3.5 mm. It has a typical maximum voltage rating of 200 volts DC with a resistance tolerance of 5%. Other features include a low temperature stability, a high pulse withstand capability, and a low etch ratio. The PF2203-1R8F1 also has a good stabilisation characteristic, which is useful for operating temperatures that are changing often.The main application of the PF2203-1R8F1 is in industrial and consumer electronics such as computers, watches, cellular phones, medical equipment, test and measurement equipment, audio-visual equipment, and more. It is also used in a variety of automotive circuits, including but not limited to, engine control systems, airbag systems, and fuel injection systems.The working principle of the PF2203-1R8F1 is simple, it is the same as most other resistors. When a current passes through it, the resistor will reduce the current flow. This is achieved through the resistance of the material the resistor is made from and the size of the conductor. This will result in a lower output voltage, and therefore reduced current flow. This simple principle is used to control and regulate the flow of current in a range of electronic circuits.Through hole resistors such as the PF2203-1R8F1 are useful components that can be used in a wide variety of applications. Not only do they reduce the flow of current in a circuit, but they also provide many other features, such as a low temperature stability, a high pulse withstand capability, and a low etch ratio. As a result, the PF2203-1R8F1 is a great option for any circuit that requires a simple and effective component.
