1k Ohm Resistor 1/4w

The 1k? Resistor is a high-quality 1/4 Watt metal film resistor offering precise and stable resistance for a wide range of electronic applications. Featuring a tight 1% tolerance , it provides consistent performance and accurate readings in both analog and digital circuits. Metal film resistors are favored for their low noise , excellent thermal stability , and long-term accuracy , making them ideal for sensitive electronic designs. The 1 kilo-ohm (1k?) value is one of the most frequently used resistor values in electronics. It is commonly employed in pull-up and pull-down resistor networks for digital input pins, LED current limiting when driving LEDs from 5V or higher, voltage divider circuits , and transistor base biasing . This makes the 1k? resistor a true workhorse component in any maker's toolbox. Designed in a standard axial-lead through-hole package , it integrates easily with breadboards, perfboards, and PCBs , making it suitable for both prototyping and final builds . It is fully compatible with all popular development platforms including Arduino, Raspberry Pi, ESP32, ESP8266, STM32, and PIC microcontrollers , and has been tested extensively in real-world DIY projects.
