Description

A 220 Ohm 2W 5% Through Hole Resistor is an electronic component used to limit the current flow in a circuit, ensuring proper voltage and current levels for various devices. Here's a more detailed description:

Key Features:

1. Resistance Value: The resistor has a resistance of 220 Ohms (Ω), meaning it resists the flow of electrical current in a circuit to this specific value.

2. Power Rating: The resistor is rated for 2 watts (2W) of power dissipation, indicating the maximum amount of power it can handle before potentially overheating or failing. This makes it suitable for moderate power applications, ensuring it can safely handle the current without excessive heat generation.

3. Tolerance: With a 5% tolerance, the actual resistance value may vary by ±5% from the nominal value of 220 Ohms. This tolerance is standard for most general-purpose resistors, allowing for slight variations in resistance while still providing reliable performance in most circuits.

4. Through Hole Mounting: This resistor is designed for through-hole mounting, meaning it has metal leads that are inserted into holes on a printed circuit board (PCB) and soldered into place. This type of resistor is commonly used in traditional electronic circuit assemblies, where durability and secure placement are essential.

5. Size and Form Factor: The resistor typically comes in a standard size, such as the axial leaded format, where the leads are at either end of the resistor body, making it easy to handle and install in various electronic applications.

6. Applications: The 220 Ohm resistor is commonly used in low- to moderate-power applications where controlling current flow is necessary, such as in:

   • LED current limiting
   • Voltage dividers
   • Signal processing circuits
   • General-purpose electronics projects
   • Power supplies or amplifiers (depending on the specific needs of the circuit)

7. Construction: Typically constructed from a resistive element made of carbon film or metal oxide, this resistor offers reliable performance over time. The ceramic body ensures insulation and resistance to heat, while the leads are usually made of tinned copper for durability.

Specifications:

• Nominal Resistance: 220 Ohms
• Power Rating: 2 Watts
• Tolerance: ±5%
• Mounting Type: Through Hole
• Material: Carbon film or metal oxide (depending on manufacturer)
