Product Description (Detailed):

Achieve precise current limiting and signal conditioning in your electronic circuits with our versatile 220Ω Carbon Film Resistor. Commonly known as a 220 Ohm resistor or 220R resistor, this essential passive component is a staple in every electronics enthusiast's and professional's toolkit. Each resistor features a reliable ¼ Watt (0.25W) power rating, making it perfectly suited for a wide range of low-power applications, from hobby projects and educational kits to complex industrial designs. The carbon film construction ensures stable resistance values with a standard ±5% tolerance, easily identifiable by its distinct Red-Red-Brown-Gold color code bands. This robust and cost-effective design is ideal for ensuring optimal current flow, protecting sensitive components like LEDs, and configuring pull-up or pull-down networks.

Our axial lead through-hole resistors are designed for effortless integration into breadboards, stripboards, and printed circuit boards (PCBs), providing excellent mechanical stability for both temporary and permanent setups. With a typical maximum working voltage of 250V and an operating temperature range generally from -55°C to +150°C, these resistors offer dependable performance across various environmental conditions. Whether you're building a simple LED circuit, developing a sensor interface for an Arduino or Raspberry Pi, or creating more intricate analog and digital designs, the 220 Ohm carbon film resistor plays a critical role. It precisely controls current flow according to Ohm's Law ($I=V/R$), ensuring the longevity of your active components and the correct operation of your circuits. Invest in these high-quality 220 Ohm resistors for accurate performance, durability, and a smooth experience in all your electronic endeavors.

The 220Ω resistor is one of the most commonly used resistors in electronics, especially for limiting current to LEDs to protect them from overvoltage or overcurrent. It is also useful in digital logic level matching, voltage dividers, and transistor base biasing.

With a power rating of ¼ watt, it is suitable for low-power circuits and educational kits. The resistor features the standard 4-band color code and tinned axial leads, making it easy to use in both breadboard and soldered circuits.
