4.7k Ohm Resistor 1/4w

The 4.7k? Resistor is a high-quality 1/4 Watt metal film resistor engineered to provide accurate and stable resistance for 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 ideal for sensitive electronic designs. The 4.7 kilo-ohm (4.7k?) value is one of the most popular and frequently used resistor values in modern electronics. It is the standard pull-up resistor for I²C communication buses (SDA and SCL lines) used by countless modules including OLED displays, BMP280, MPU6050, and RTC modules . It is also the recommended pull-up value for OneWire sensors like the DS18B20 temperature sensor . Beyond pull-ups, it's commonly used in voltage dividers, transistor biasing, and analog signal conditioning . Designed in a standard axial-lead through-hole package , this resistor easily integrates with breadboards, perfboards, and printed circuit boards (PCBs) , making it ideal for rapid prototyping and permanent installations . It is fully compatible with all major development platforms, including Arduino, Raspberry Pi, ESP32, ESP8266, STM32, and PIC microcontrollers . Specifications Resistance Value: 4.7 k?
