Description

A 12K Ohm 1/4W 5% Through Hole Resistor is a commonly used electronic component that plays a crucial role in controlling the flow of electrical current within a circuit. It is designed with a resistance value of 12,000 ohms (12K), which means it limits the current flow to that specific resistance level, making it ideal for various applications such as voltage dividers, current limiting, and signal conditioning.

Key specifications of this resistor include:

• Resistance: 12K ohms, which is the value of resistance the resistor provides to the circuit. This resistance ensures that the current is limited according to Ohm’s law.
• Power Rating: 1/4 watt (0.25W), which refers to the maximum power the resistor can dissipate without overheating or being damaged. It is suitable for low power applications.
• Tolerance: 5%, meaning the actual resistance value can vary by ±5% from the stated nominal resistance of 12K ohms. This tolerance is typical for general-purpose resistors and is sufficient for most non-precision applications.
• Package Type: Through hole, meaning the resistor is designed to be inserted into holes on a printed circuit board (PCB) and soldered from the opposite side. This is a common form factor in traditional, hand-soldered circuit assemblies.
• Construction: Typically made from a metal oxide or carbon composition, providing stability and reliability in a variety of environments. The resistor’s body is cylindrical with color-coded bands to indicate its resistance value and tolerance.

This resistor is often used in a variety of general-purpose electronics, such as in power supplies, amplifiers, analog circuits, and digital circuits. Its small size and efficiency make it an essential component in a wide range of low-power electrical designs. The 12K Ohm 1/4W 5% Through Hole Resistor is ideal for applications that require modest resistance and tolerance, such as in signal processing and simple electronic devices.

Applications:

• Voltage dividers and current limiting circuits.
• General-purpose electronics in hobbyist projects and prototyping.
• Digital and analog circuit design.

Safety Considerations: It is important to ensure that the resistor operates within its power rating (1/4W) to prevent overheating and potential damage. Overloading a resistor beyond its power rating can lead to component failure, circuit damage, and even fire hazards. Always verify the appropriate resistor value for your application to ensure optimal performance and safety.
