3 Ohm (3E) 1/4W 5% Through Hole Resistor

The 3 Ohm (3E) 1/4W 5% Through Hole Resistor is a versatile and reliable component commonly used in a wide range of electronic circuits. Its moderate resistance, low power dissipation, and durable mounting style make it suitable for both professional designs and hobbyist projects. Here's a detailed breakdown of its key features:

Resistance Value (3 Ohms):

This resistor has a resistance of 3 ohms, which offers a balanced level of current limiting. It is often used in circuits that require moderate resistance to regulate current flow without introducing excessive heat. The 3-ohm value is suitable for power supply circuits, LED drivers, and sensor applications where precise current control is needed.

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

With a 1/4 watt (0.25W) power rating, this resistor is designed to safely dissipate up to 0.25 watts of electrical energy in the form of heat. It is ideal for low-power applications, ensuring that the resistor doesn't overheat and remains reliable even in long-term use.

Tolerance (5%):

The 5% tolerance indicates that the actual resistance can vary by up to ±5% from the nominal value of 3 ohms. This level of tolerance is standard for general-purpose resistors, offering an acceptable level of variation for most applications where precise resistance values are not critical but consistency is required.

Through-Hole Mounting:

This resistor features a through-hole design, which means it has leads that are inserted through holes in a printed circuit board (PCB) and soldered on the opposite side. The through-hole mounting style is robust, making it easy to install, replace, or repair, which is especially beneficial for prototyping and DIY electronics.

Material and Durability:

Typically made from carbon film or metal oxide, this resistor is durable, reliable, and cost-effective. It is designed to withstand typical operating conditions in low-power circuits and is well-suited for general-purpose applications where longevity and performance are key.

Applications:

• Current Limiting: The 3-ohm resistor is excellent for current-limiting applications, such as in LED circuits, where it helps control the amount of current flowing through the LED to prevent damage or to adjust the brightness.

• Voltage Division: It can be used as part of a voltage divider network, creating specific voltage levels in circuits for sensors or analog signal conditioning.

• Signal Filtering: The resistor can be used in filter circuits, often in conjunction with capacitors or inductors, to filter out unwanted frequencies or noise, especially in audio and RF applications.

• Power Regulation: In circuits that require stable power delivery, this resistor can help regulate current to ensure that sensitive components receive the appropriate amount of power.

Ease of Handling and Repair:

With its through-hole design, the resistor is easy to solder and remove from PCBs, making it a great choice for both prototype development and repair work. If a circuit needs modification or if a resistor fails, this component can be easily swapped out or adjusted.

In Summary:

The 3 Ohm (3E) 1/4W 5% Through Hole Resistor is a reliable and affordable component that offers moderate resistance, low power dissipation, and a robust through-hole mounting. It’s well-suited for applications like current limiting, voltage division, signal filtering, and power regulation in low-power electronic circuits. Its ease of handling and versatility make it a perfect choice for both hobbyists and professional engineers working on general-purpose electronic designs.

This resistor's 3-ohm value is ideal for circuits that need a balance between current limiting and voltage regulation. If you need more specific applications or further details, feel free to ask!
