150 Ohm Resistor 1/4w

The 150? 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 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 150 ohm value is a standard E96-series resistor commonly used in LED current limiting circuits , particularly when driving high-brightness or high-efficiency LEDs from 3.3V and 5V supplies like 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 . Specifications Resistance Value: 150 Ohm (?)
