Description

A 7.5 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (7.5 Ohms):

This resistor has a resistance of 7.5 ohms, which means it provides a moderate resistance to the flow of electrical current. A 7.5-ohm resistor is commonly used in applications that require current limiting, voltage division, or impedance matching. It's often found in circuits dealing with moderate power levels or circuits involving audio, signal processing, or low-power devices like LEDs or sensors.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating means this resistor is designed to safely dissipate up to 0.25 watts of heat without being damaged. In circuits with a 7.5-ohm resistor, the power dissipation is generally low to moderate, so this rating ensures the resistor can handle the heat generated by typical current flow without failure.

Tolerance (5%):

The 5% tolerance means that the actual resistance of the resistor can vary by up to ±5% from the nominal value of 7.5 ohms. This means the resistor could fall within a range of 7.125 ohms to 7.875 ohms. While there is some variation, this tolerance is standard for general-purpose resistors and is usually acceptable for most applications that do not require high precision.

Through-Hole Mounting:

This resistor is designed for through-hole mounting, meaning it has leads that pass through holes in a printed circuit board (PCB) and are soldered in place. Through-hole resistors provide a solid mechanical connection, making them durable and reliable for use in prototypes, permanent installations, or applications where component replacement or modifications may be necessary.

Applications:

• Current Limiting: The 7.5-ohm resistor can be used to limit the current in circuits, such as LED drivers or other low-power devices, protecting sensitive components from excessive current.
• Voltage Division: This resistor is often part of voltage divider circuits, where it helps to create specific voltage levels needed by other parts of the circuit.
• Impedance Matching: In audio and signal processing circuits, a 7.5-ohm resistor may be used to match impedances between components, optimizing signal flow and minimizing loss.
• Power Regulation: The resistor could be part of power regulation or filtering circuits, controlling the flow of power to ensure safe operation of components.

Summary:

The 7.5 Ohm 1/4W 5% Through Hole Resistor is ideal for applications requiring moderate current limiting, voltage division, or impedance matching. The 1/4W power rating ensures that the resistor can safely dissipate heat in low to medium-power circuits, while the 5% tolerance ensures it performs accurately enough for general-purpose use. Through-hole mounting makes it durable and easy to handle, especially in prototypes and designs where mechanical strength and ease of replacement are important.
