68k Ohm Resistor 1/4w

The 68k? 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 68 kilo-ohm (68k?) value is a standard E96-series resistor commonly used in RC timing networks with 555 timer ICs , voltage dividers , transistor base biasing , and op-amp feedback circuits . It's a popular choice for medium-impedance applications that require moderate current limiting while maintaining minimal load on signal sources. It's also widely used in audio circuits, sensor scaling networks, and pull-up resistors for low-current digital lines . 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: 68 k?
