Description

A 15 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (15 Ohms):

This resistor has a resistance of 15 ohms, meaning it provides a moderate level of opposition to the flow of electrical current. A 15-ohm resistor is commonly used in applications requiring current limiting, voltage division, or power regulation. It is widely used in circuits such as LED drivers, signal processing, and voltage drop applications, as well as in low-power power supply systems.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating indicates that this resistor can safely dissipate up to 0.25 watts of heat without damage. Given its 15-ohm resistance, the resistor is designed for low-power applications, where the current passing through it won’t generate enough heat to exceed the power rating. This ensures safe and efficient operation in typical circuit conditions.

Tolerance (5%):

The 5% tolerance means that the actual resistance of the resistor can vary by ±5% from its nominal value of 15 ohms. This means the resistor could have an actual resistance between 14.25 ohms and 15.75 ohms. The 5% tolerance is standard for general-purpose resistors and is typically acceptable for most applications where high precision is not crucial.

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 on the opposite side. Through-hole resistors provide strong mechanical and electrical connections, making them ideal for both prototyping and final designs where durability and reliability are important. They are easy to handle and replace, particularly useful in applications requiring component changes or circuit modifications.

Applications:

• Current Limiting: A 15-ohm resistor is commonly used in circuits where current needs to be limited to protect components like LEDs or transistors from excessive current. It helps ensure that sensitive components operate within safe current ranges.
• Voltage Division: It is used in voltage divider circuits, where it works with another resistor to create specific voltage levels needed by other parts of the circuit.
• Impedance Matching: In audio or RF (radio frequency) circuits, a 15-ohm resistor can be used for impedance matching, optimizing signal transfer and reducing reflections.
• Power Regulation: It can be part of power distribution circuits, helping regulate voltage or current to ensure stable operation of other components in the system.

Summary:

The 15 Ohm 1/4W 5% Through Hole Resistor is a versatile resistor commonly used in circuits for current limiting, voltage division, and impedance matching. The 1/4W power rating ensures it can handle heat dissipation safely in low-power applications, while the 5% tolerance ensures it provides reasonable accuracy for most general-purpose uses. The through-hole mounting style ensures a strong, durable connection, making it ideal for both prototyping and finalized designs where easy replacement or modification is required.
