Through Hole Resistors are an indispensable part within any electronic circuit. The device converts an electrical current into a resistance and is used to control, regulate, adjust, and protect electrical signals. The PF2472-0R75F1 Through Hole Resistor from Panasonic, for example, is a part of the RoHS compliant PF2472 series, with a rated power of 1/2W and a resistance of 75 Ohms.

The PF2472-0R75F1 has two main application fields: as an automatic antenna tuning device and as a power device. In the case of antenna tuning, it acts as a radio frequency (RF) signal attenuator that helps regulate the signal strength depending on the various tuning parameters. As a power device, it helps control the current going to the load by adjusting its resistance value. This is an extremely useful function in overload protection and amplitude regulation, since the resistor can be used to reduce the output voltage in case of an overcurrent condition.

The working principle of the PF2472-0R75F1 Through Hole Resistor is based on its carbon composition material. Inside this component, the carbon nanoparticles, mixed in the metal-oxide paste, form an electrical contact inside the component’s resistively element. This contact helps to regulate the electrical flow and determines the resistor’s resistance value. The resistor also has an operating temperature range of -55°C to +155°C.

The PF2472-0R75F1 is available in three different sizes: 1005, 1206, and 1210. The package style of the component is Axial, which means that the two lead wires come out of the resistor body in the same direction. The end terminals are notched for ease of mounting. The resistor is also non-magnetic, as expected for an electronic an component.

The PF2472-0R75F1 is a good choice for applications where an accurate and precise resistor value is needed - for controlling power, regulating current or voltage, and maintaining a consistent electrical signal. It is especially useful in overload protection and RF antenna tuning, where its reliable performance will ensure the long-term reliability of the circuit. The component is a great choice for both engineers and hobbyists who are looking for a high-performance through hole resistor that can handle high power and temperature conditions.
