470k Ohm Resistor 1W

The 470k? 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 especially suitable for high-impedance and precision circuits . The 470 kilo-ohm (470k?) value is a standard E96-series resistor widely used where high resistance and minimal current draw are required. Common applications include RC timing networks with 555 timer ICs , op-amp feedback resistors for high-gain configurations, high-impedance voltage dividers for battery monitoring on microcontroller analog pins, and biasing FET/JFET input stages . It's also commonly used in audio preamplifier inputs , transistor leakage protection , and low-frequency filter circuits . Manufactured in a standard axial-lead through-hole package , this resistor easily integrates 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: 470 k?
