Through hole resistors are used in applications when the PCB layout requires a wire connection from the component backside. This type of resistors are preferred as they offer a better electrical contact when soldering than surface mount components, and they are also more durable. PF2472-330RF1 is a through hole resistor and is commonly used for power protection, motor control and general purpose applications. In this article, we will discuss the application field and working principle of the PF2472-330RF1.

Applications of PF2472-330RF1

The main application of the PF2472-330RF1 is as a current limiter. It is especially useful when controlling or limiting the amount of current flowing through a circuit. For example, it can be used to protect electrical components from overloading or to regulate a motor\'s current consumption. Additionally, the device can also be used in power supply circuits, where the PF2472-330RF1 acts as a voltage regulator, ensuring a stable output voltage.

The device can also be used to provide protection against over-voltage surges, which can cause damage to the circuit and equipment. It works by limiting the voltage to a predetermined level thereby providing the necessary protection. Aside from over-voltage protection, the PF2472-330RF1 can also be used as a noise filter in audio circuits, providing a low frequency and broad-band attenuation of unwanted frequencies.

Working Principle of PF2472 - 330RF1

PF2472-330RF1 is a through hole resistor with a tolerance of ±5%, a power rating of 2 watt, and a resistance value of 330 ohm. It is constructed of two sintered copper elements, which are wrapped around a ceramic core body. The two elements are connected by thin wires (called leads) that exit through the base of the resistor. The two leads are then inserted into a hole in a PCB board and soldered in place.

When electricity passes through the resistor, some is converted into heat energy, which delays the flow of current. This delay of current flow is referred to as resistance, and it is measured in ohms. The higher the resistance, the less current flow through the circuit. The PF2472-330RF1has an 330 ohm resistance, which is suitable for protecting and limiting the current flow in a variety of applications.

The PF2472-330RF1 also has a number of other special characteristics that make it an ideal current limiter for a variety of applications. It has excellent temperature and voltage coefficient stability, and it is also flame retardant. Additionally, it has an extended operating temperature range (-55°C to +125°C) and low inductance. These features make it suitable for applications with high shock and vibration levels.

Conclusion

The PF2472-330RF1 is a through hole resistor and is commonly used for power protection, motor control, and general purpose applications. It is especially suitable for current limitation and over-voltage protection. It is constructed of two sintered copper elements, which are connected by two leads. It offers excellent temperature and voltage coefficient stability, and it is also flame retardant. With all these features, the PF2472-330RF1 is a reliable and cost-effective solution for a variety of applications.
