82 Ohm 1/4 Watt Resistor

The 82 Ohm 1/4 Watt Resistor is a fixed-value passive electronic component designed to regulate current flow, divide voltage, and protect sensitive electronic components in electrical and electronic circuits. With a resistance value of 82 Ohms (82Ω) and a power rating of 1/4 Watt (0.25W), this resistor is suitable for a wide range of low-power applications, including LED current limiting, voltage divider networks, transistor biasing, signal conditioning, embedded systems, and DIY electronics projects.

Resistors are among the most commonly used components in electronic circuits because they control the amount of electrical current flowing through a circuit. By limiting current and producing controlled voltage drops, they help ensure the safe and reliable operation of LEDs, transistors, integrated circuits (ICs), sensors, microcontrollers, and other electronic devices.

The 82 Ohm resistor is manufactured using high-quality carbon film or metal film technology to provide accurate resistance, low electrical noise, and stable long-term performance. It features a through-hole axial lead design, making it easy to install on printed circuit boards (PCBs), breadboards, stripboards, and prototype boards. The compact size and lightweight construction make it suitable for students, hobbyists, repair technicians, and professional electronics engineers.

With a tolerance of ±5%, the resistor maintains its resistance value within acceptable limits for most general-purpose electronic applications. The 0.25 Watt (1/4 Watt) power rating allows it to safely dissipate heat generated during normal operation when used within its specified limits.

The 82 Ohm 1/4 Watt Resistor is widely used in Arduino projects, Raspberry Pi projects, AVR microcontroller circuits, robotics, educational electronics kits, electronic repairs, and general circuit development.
