PF2205-1R5F1

Through Hole Resistors

Through hole resistors are one of the most commonly used components in electronics. They are used to control the amount of current flowing through circuits by providing a certain resistance. Resistor technology has come a long way since the early days of vacuum tubes, and modern resistors are designed for a wide range of applications with various performance characteristics. A common through hole resistor is the PF2205-1R5F1, which is typically used in AC lines, inverters, controllers, and motor control circuits.

PF2205-1R5F1 Application Field

The PF2205-1R5F1 is a standard component of a variety of different precision control systems, including AC lines, inverters, controllers, and motor drive circuits. It is especially useful in these precision circuits where its high resistance accuracy and low-temperature stability are both required. Due to its low-temperature coefficient and long-term stability characteristics, these resistors have been used in applications such as control inverters for solar power systems, air conditioners, HVAC systems, and robot controllers.

PF2205-1R5F1 Working Principle

The PF2205-1R5F1 is composed of two metal layer chips on an insulated ceramic board, which is composed of resistive elements, capacitor elements, and insulating layers. Its resistance is regulated by changing the amount of current flowing through it. When a specific amount of current is passed through the resistor, it will produce a voltage drop in the form of heat. As the heat dissipates, the resistance of the resistor will increase ever so slightly, stabilize, and return to its initial value.

These resistors also feature incredibly low temperatures coefficients. This means that even when exposed to varying ambient temperatures, the resistance of these resistors will remain virtually unchanged, allowing them to maintain accuracy and stability in challenging temperatures.

Conclusion

The PF2205-1R5F1 is a versatile and long-lasting component, offering consistent performance for a variety of precision control applications such as AC lines, inverters, controllers, and motor drive circuits. Its stable resistance characteristics and low-temperature coefficient make it suitable for these temperature-dependent applications, while its long-term stability ensures reliable performance in the long run.
