100k Ohm Resistor 1W

The 100k? Resistor is a high-quality 1/4 Watt metal film resistor engineered to deliver accurate and stable resistance in a wide variety of electronic circuits. With a precise 1% tolerance , it ensures consistent and predictable performance in both analog and digital applications. Metal film resistors are preferred over carbon film types because they offer lower noise , superior thermal stability , and higher long-term accuracy , making them especially well-suited for high-impedance and precision circuits . The 100 kilo-ohm (100k?) value is one of the most popular and widely used resistor values in modern electronics. It is a go-to value for RC timing circuits with 555 timer ICs , op-amp feedback networks , voltage dividers for battery monitoring on Arduino analog pins, and pull-up/pull-down configurations in microcontroller projects. It's also commonly used for transistor base biasing , MOSFET gate pull-down , and as a standard load resistor for high-impedance analog sensors and probes . Manufactured in a standard axial-lead through-hole package , this resistor integrates easily with breadboards, perfboards, and printed circuit boards (PCBs) , making it ideal for both rapid prototyping and permanent installations . It is fully compatible with all popular development platforms, including Arduino, Raspberry Pi, ESP32, ESP8266, STM32, and PIC microcontrollers . Specifications Resistance Value: 100 k?
