6.8k Ohm Resistor 1/4w

The 6.8k? 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 6.8 kilo-ohm (6.8k?) value is a standard E96-series resistor commonly used in voltage dividers , transistor base biasing , op-amp feedback networks , and medium-impedance pull-up/pull-down configurations . It's also frequently used in RC timing circuits with 555 timer ICs , audio gain-setting networks , and sensor interfacing applications . Its medium resistance value strikes a balance between low current draw and adequate signal strength , making it versatile across many electronic designs. 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: 6.8 k?
