Description

A 39 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (39 Ohms):

This resistor has a resistance of 39 ohms, meaning it offers a moderate level of resistance to the flow of electrical current. A 39-ohm resistor is often used in circuits where you need to limit current, divide voltage, or regulate power. It is commonly found in applications like LED current limiting, signal conditioning, and low-power voltage divider circuits.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating indicates that the resistor is designed to safely dissipate up to 0.25 watts of heat without being damaged. This makes the resistor suitable for low-power circuits where the current is not high enough to generate excessive heat. In typical low-power applications, the resistor will operate within safe limits, ensuring reliable performance without overheating.

Tolerance (5%):

The 5% tolerance means that the actual resistance of the resistor can vary by ±5% from the nominal value of 39 ohms. This gives a resistance range of 37.05 ohms to 40.95 ohms. The 5% tolerance is typical for general-purpose resistors and is generally acceptable for most circuits that don't require precise resistance values.

Through-Hole Mounting:

This resistor is designed for through-hole mounting, meaning it has leads that pass through holes in a printed circuit board (PCB) and are soldered on the opposite side. Through-hole mounting provides a solid and durable mechanical connection, making it ideal for applications where components need to be replaced, modified, or prototyped. It's a popular mounting style for both DIY projects and more permanent designs.

Applications:

• Current Limiting: A 39-ohm resistor is often used in circuits to limit current, such as in series with LEDs or other sensitive components to prevent excess current from damaging them.
• Voltage Division: It can be used in voltage divider circuits, where it helps create a specific voltage level for other parts of the circuit.
• Impedance Matching: In audio or RF (radio frequency) applications, a 39-ohm resistor can be used for impedance matching, ensuring the proper transfer of signals between components and reducing signal reflections.
• Power Regulation: It can be used in power regulation circuits to help manage the distribution of current and voltage, ensuring the safe operation of other components in the system.

Summary:

The 39 Ohm 1/4W 5% Through Hole Resistor is a versatile, general-purpose resistor used in various applications such as current limiting, voltage division, impedance matching, and power regulation in low-power circuits. The 1/4W power rating ensures it can safely dissipate heat without damage, while the 5% tolerance provides an acceptable level of accuracy for most standard circuit designs. The through-hole mounting style ensures a strong, durable connection, making it an excellent choice for both prototyping and final circuit designs where reliability and ease of replacement or modification are required.
