Description

A 270 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (270 Ohms):

This resistor has a resistance of 270 ohms, which provides a moderate opposition to the flow of electrical current. A 270-ohm resistor is typically used in circuits where current needs to be limited, voltage needs to be divided, or a certain level of impedance is required. It is commonly used in low- to medium-power applications, such as limiting current in LED circuits, creating voltage dividers, and in signal processing or analog circuit designs.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating means the resistor can safely dissipate up to 0.25 watts of heat without damage. This power rating is suitable for typical low-power applications where the resistor won’t be exposed to high currents that could generate excessive heat. The 1/4W rating ensures safe operation in most low-power circuits.

Tolerance (5%):

The 5% tolerance means that the actual resistance could vary by ±5% from the nominal value of 270 ohms. Therefore, the actual resistance could range from 256.5 ohms to 283.5 ohms. This tolerance is standard for general-purpose resistors and is adequate for most applications where precise resistance is not crucial, offering a good balance between performance and cost.

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 components provide secure and durable connections, making them ideal for both prototyping and final circuit assemblies. This mounting type ensures stability, which is useful in applications where the components may need to be replaced, modified, or repaired.

Applications:

• Current Limiting: A 270-ohm resistor is frequently used in series with components like LEDs to limit the current and prevent excessive current flow, ensuring that sensitive components like LEDs are not damaged by too much current.
• Voltage Division: It can be used in voltage divider circuits to divide an input voltage into smaller, more manageable voltages, which are then used by other parts of the circuit.
• Impedance Matching: In audio, RF (radio frequency), or communication circuits, a 270-ohm resistor may be used for impedance matching, helping ensure efficient signal transfer and reducing reflections.
• Power Regulation: This resistor can also be used in power regulation circuits, where controlling current or voltage is necessary to ensure stable operation of other components in the system.

Summary:

The 270 Ohm 1/4W 5% Through Hole Resistor is a general-purpose resistor often used for current limiting, voltage division, impedance matching, and power regulation in low- to medium-power circuits. The 1/4W power rating ensures safe operation under normal conditions, while the 5% tolerance provides acceptable accuracy for most general-purpose applications. The through-hole mounting design ensures a reliable and durable connection, making it ideal for both prototyping and final circuit designs where reliability, ease of modification, or replacement is important.
