Description

A 100 Ohm 1/4W 5% Through Hole Resistor is a specific type of resistor with the following characteristics:

Resistance Value (100 Ohms):

This resistor has a resistance of 100 ohms, which means it provides a moderate level of resistance to the flow of electrical current. A 100-ohm resistor is commonly used in circuits for applications like current limiting, voltage division, and filtering. It can be found in various low- to medium-power applications, such as limiting current in LED circuits, voltage dividers, and signal processing circuits.

Power Rating (1/4W):

The 1/4 watt (0.25W) power rating indicates that this resistor is designed to safely dissipate up to 0.25 watts of heat. This power rating is suitable for most low-power applications where the current passing through the resistor is not high enough to generate significant heat. The 1/4W rating ensures that the resistor operates safely without overheating under normal conditions.

Tolerance (5%):

The 5% tolerance means that the actual resistance can vary by ±5% from the nominal value of 100 ohms. Therefore, the actual resistance could range from 95 ohms to 105 ohms. This level of tolerance is typical for general-purpose resistors and is adequate for most applications where precise resistance values are not critical.

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. This type of mounting provides a reliable, stable connection and is ideal for prototyping, permanent circuit designs, or when components may need to be replaced or modified.

Applications:

• Current Limiting: A 100-ohm resistor is commonly used in series with components like LEDs to limit the current and prevent overcurrent that could damage the components.
• Voltage Division: It can be used in voltage divider circuits to reduce or divide an input voltage into smaller, more manageable levels needed for other parts of the circuit.
• Impedance Matching: In audio or RF (radio frequency) circuits, a 100-ohm resistor is often used for impedance matching to optimize signal transfer and minimize signal reflections.
• Power Regulation: The resistor can also be used in power regulation circuits to help control the flow of voltage and current to ensure other components operate within their specified limits.

Summary:

The 100 Ohm 1/4W 5% Through Hole Resistor is a versatile, general-purpose resistor that is used in applications such as current limiting, voltage division, impedance matching, and power regulation. The 1/4W power rating ensures it operates safely under typical low-power conditions, while the 5% tolerance provides acceptable accuracy for most general-purpose applications. The through-hole mounting design guarantees a reliable and durable connection, making it ideal for both prototyping and finalized circuit designs where component reliability and the ability to replace or modify parts are important.
