5.1k Ohm Resistor 1/4w

The 5.1k? 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 well-suited for sensitive electronic designs. The 5.1 kilo-ohm (5.1k?) value is a standard E96-series resistor with several important uses in modern electronics. It is the official pull-down value for USB-C CC (Configuration Channel) lines , used to identify a device as a USB-C sink (power consumer) — making it essential for DIY USB-C power delivery projects . It is also commonly used in voltage dividers, transistor biasing, op-amp feedback networks, and pull-up/pull-down configurations in microcontroller-based circuits. 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: 5.1 k?
