47k Ohm Resistor 1/4w

The 47k? Resistor is a high-quality 1/4 Watt metal film resistor designed 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 47 kilo-ohm (47k?) value is one of the most popular and frequently used resistor values in electronics. It is widely used as a pull-up or pull-down resistor for high-impedance digital inputs, in RC timing networks with 555 timer ICs , as a gate pull-down resistor for MOSFETs , in op-amp feedback paths , and in high-value voltage dividers for analog signal scaling. It's also a popular choice for transistor base biasing in low-current switching circuits and for interfacing with high-impedance sensors . 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: 47 k?
