Description

The 1 Ohm 1/4W 5% Through Hole Resistor is a commonly used electronic component. Here is a detailed description of its characteristics:

1. Resistance Value (1 Ohm):

• The 1 ohm resistance means the resistor limits the flow of electric current by providing a resistance of 1 ohm. This relatively low value allows a significant amount of current to pass through, which is useful in applications where only a small amount of resistance is needed to control or regulate current flow.

2. Power Rating (1/4W or 0.25W):

• The 1/4 watt (0.25W) power rating means that this resistor can safely dissipate up to 0.25 watts of power without overheating. This is suitable for low-power applications where the resistor does not need to absorb a significant amount of energy.

3. Tolerance (5%):

• The 5% tolerance indicates that the actual resistance could vary by ±5% from the nominal value of 1 ohm. This means the resistor could have a resistance anywhere between 0.95 ohms and 1.05 ohms. This tolerance level is typical for general-purpose resistors and is acceptable in many electronic circuits.

4. Through-Hole Mounting:

• This resistor uses a through-hole mounting style, which means it has two metal leads that are inserted into holes in a printed circuit board (PCB) and soldered on the other side. Through-hole resistors are typically used in applications that require more physical robustness and are often favored in prototyping, DIY projects, or situations where the circuit might need to be serviced or modified.

5. Material and Construction:

• The resistor is generally made of materials like carbon film or metal oxide, which offer stability and reliability. Carbon film resistors are widely used for their cost-effectiveness, while metal oxide resistors offer better durability, particularly in high-temperature or high-power applications.

Applications:

• Current Limiting: The 1-ohm resistor is useful in circuits that require current regulation. It can limit current flow in power supplies, LED circuits, or battery-operated devices.
• Voltage Divider: It can be used as part of a voltage divider circuit, where it works in conjunction with other resistors to create specific voltage levels.
• Signal Processing: In combination with other components (capacitors or inductors), it can be used in signal-processing circuits, including filters or amplifiers.
• Pull-down or Pull-up Resistors: In digital circuits, 1-ohm resistors can sometimes be used as pull-down or pull-up resistors in logic circuits, although they are often more suitable for low-resistance tasks.

Summary:

The 1 Ohm 1/4W 5% Through Hole Resistor is a reliable and versatile resistor used for various applications, including current limiting, voltage division, and signal processing. Its 1-ohm resistance, 1/4W power rating, and 5% tolerance make it a suitable choice for general-purpose electronic circuits, and its through-hole mounting style ensures easy installation and stability in a variety of PCB designs.
