Description

A 12 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (12 Ohms):

This resistor has a resistance of 12 ohms, which means it offers moderate resistance to the flow of electrical current. The 12-ohm value is commonly used in circuits where you need to limit current, create voltage dividers, or control power dissipation. It is often found in applications like LED current limiting, signal processing, or voltage regulation circuits.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating means the resistor is designed to safely dissipate up to 0.25 watts of heat. Given its resistance value, this resistor is intended for low-power applications. It can handle typical current flow without overheating, ensuring safe and efficient operation in circuits where power dissipation is minimal.

Tolerance (5%):

The 5% tolerance means that the actual resistance of the resistor can vary by ±5% from the nominal value of 12 ohms. This means the resistance could range from 11.4 ohms to 12.6 ohms. This tolerance is common for general-purpose resistors and is typically sufficient for most standard circuit applications where exact precision is not critical.

Through-Hole Mounting:

This resistor is designed for through-hole mounting, which means it has leads that pass through holes in a printed circuit board (PCB) and are soldered on the opposite side. Through-hole mounting provides strong mechanical and electrical connections, making it a reliable choice for both prototype and permanent designs. It is especially useful in situations where components might need to be replaced or for applications that require durability and ease of modification.

Applications:

• Current Limiting: A 12-ohm resistor is commonly used in circuits to limit the current, such as in LED drivers or to protect sensitive components from excessive current.
• Voltage Division: It can be used in voltage divider circuits, where the resistor helps create specific voltage levels required by other parts of the circuit.
• Impedance Matching: It is often used in applications where impedance matching is important, such as audio equipment, to ensure proper signal flow and minimize power loss.
• Power Regulation: The resistor may also be part of power regulation circuits, helping to control the distribution of power to various components in the system.

Summary:

The 12 Ohm 1/4W 5% Through Hole Resistor is a versatile and general-purpose resistor used in applications requiring moderate current limiting, voltage division, or impedance matching. The 1/4W power rating ensures it can safely handle heat dissipation in low-power circuits, while the 5% tolerance offers adequate accuracy for most standard applications. Its through-hole mounting design makes it durable, easy to handle, and ideal for both prototyping and permanent circuit designs where mechanical strength and ease of replacement are necessary.
