2k Ohm Resistor 1/4w

The 2k? 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 precision designs. The 2 kilo-ohm (2k?) value is a standard E96-series resistor commonly used in voltage divider circuits , transistor base biasing , and pull-up/pull-down configurations . It is also frequently used in op-amp gain networks , analog signal scaling , and as a current limiter in low-current LED indicators. Its value is well-suited for 5V and 3.3V microcontroller systems , making it a versatile component in mixed analog/digital 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 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: 2 k?
