PF2205-1R1F1

Through-hole resistors are resistors that are designed to be directly soldered to a printed circuit board. They are distinct from surface mount resistors, which are soldered to solder pads on the surface of a circuit board, instead of being mounted down through drilled holes. The PF2205-1R1F1 through-hole resistor is a popular choice for many application fields. It is an axial-lead resistor with a power rating of 1/4 watt, a resistance of 1.1 ohms and a tolerance of 1%. This article will discuss the application fields of the PF2205-1R1F1, as well as its working principle.

Applications

The PF2205-1R1F1 through-hole resistor is a popular choice for a variety of applications that require low-power resistors, such as surge protection circuits, high-voltage circuits, and DC/DC converters. The resistor is also well-suited for use in audio frequency applications, such as preamp overdrive circuits, and low pass filter designs. Additionally, the PF2205-1R1F1 can be used in a wide range of general-purpose applications, such as limiting voltages in bass and treble control circuits, and decoupling signals for better circuit protection.

Working Principle

The PF2205-1R1F1 through-hole resistor operates on the same principle that all resistors do: it resists the flow of current. The resistor has a resistance value of 1.1 ohms, meaning that it will oppose the flow of current by 1.1 ohms. In order for current to be able to flow through the resistor, a voltage must be applied across its leads. If the voltage is greater than the resistor’s rated power rating, the resistor will begin to heat up, resulting in increased resistance and, if left unchecked, eventual failure of the component. It is important to select an appropriate power rating for a given application to ensure that the resistor can handle the rated voltage without over-heating.

Conclusion

The PF2205-1R1F1 through-hole resistor is a popular choice that can be used in a wide range of applications, from surge protection to audio frequency applications. It operates on the same principle as all resistors, resisting the flow of current, and it must be matched with an appropriate power rating to ensure that it does not overheat when a voltage is applied across its leads.
