The 200Ω Resistor is a high-quality 1/4 Watt metal film resistor engineered to provide accurate and stable resistance in a wide variety of electronic applications. With a precise 1% tolerance, it ensures consistent and predictable performance for both analog and digital circuits. Metal film resistors are preferred over carbon film types because they deliver lower noise, superior thermal stability, and higher long-term accuracy, making them ideal for sensitive electronic designs.
The 200 ohm value is a standard E96-series resistor commonly used in LED current limiting circuits, particularly when driving standard or high-efficiency LEDs from 5V supplies such as Arduino, ESP32, and Raspberry Pi outputs. It provides a balanced trade-off between bright LED output and safe forward current. Beyond LEDs, this resistor is also widely used in voltage dividers, transistor biasing, MOSFET gate networks, and pull-up/pull-down configurations.
Built in a standard axial-lead through-hole package, this resistor easily integrates with breadboards, perfboards, and printed circuit boards (PCBs), making it ideal for both rapid prototyping and permanent project builds. It is fully compatible with all popular development platforms, including Arduino, Raspberry Pi, ESP32, ESP8266, STM32, and PIC microcontrollers.
