Description

The 1 Ohm 2W 5% Through Hole Resistor is a commonly used electronic component with the following key specifications:

Specifications:

• Resistance Value: 1 ohm (Ω)
• Power Rating: 2 watts (W)
• Tolerance: ±5% (The actual resistance may vary within a 5% range of the nominal value.)
• Mounting Type: Through hole (The resistor has leads that pass through holes on a printed circuit board (PCB) for soldering.)
• Package Type: Typically cylindrical or rectangular, designed for through-hole mounting, commonly used in power applications.

Key Features:

• 1 Ohm: This resistance value is often used for current sensing, power dissipation, or voltage drop applications. It is a relatively low resistance, ideal for applications where the current needs to be regulated or controlled, and a small voltage drop is desired.

• 2W Power Rating: With a power rating of 2 watts, this resistor can safely dissipate up to 2 watts of power. This makes it suitable for higher power applications, as compared to lower-rated resistors such as 0.25W or 0.5W, which are designed for lower power dissipation.

• 5% Tolerance: The resistor can have an actual resistance value within ±5% of 1 ohm, meaning the resistance may range between 0.95 ohms and 1.05 ohms. This level of tolerance is commonly accepted for many general-purpose applications where precise accuracy is not critical but reliable performance is still necessary.

Typical Applications:

• Current Limiting: This resistor can be used to limit current in circuits, such as in power supplies or motor driver circuits. It can act as a current-sensing resistor to prevent excessive current flow.

• Power Circuits: Suitable for applications in power electronics where moderate to high power dissipation is expected. It can be used in voltage regulators, amplifiers, and other circuits that require power regulation and control.

• Current Sensing: Due to its 1-ohm value, this resistor is often used in current-sensing applications, such as in battery management systems or circuit protection devices.

• Audio Amplifiers: It can also be used in audio circuits, such as power amplifiers, where controlling or limiting current is important to avoid overloading and ensure stable operation.

• High-Current Circuits: Given its 2W power rating, this resistor is appropriate for circuits with relatively high current flow, such as motor control systems, power distribution, and power conditioning applications.
