The 100kΩ 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 (100kΩ) 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.
