Product Description (Detailed):

A fundamental building block in countless electronic designs, the 4.7k Ohm ¼ Watt Carbon Film Resistor is a ubiquitous passive component found in hobbyist projects, educational kits, and professional circuits alike. With a resistance value of 4700 Ohms ($4.7k\Omega$) and a power dissipation rating of ¼ Watt (0.25W), this resistor offers a reliable and cost-effective solution for a broad spectrum of low-power and general-purpose applications.

Carbon film resistors are well-regarded for their stability, good temperature coefficient, and affordability. They are manufactured by precisely depositing a thin carbon film onto a ceramic substrate, with a helical cut to achieve the exact resistance. This specific 4.7k Ohm resistor typically comes with a standard $\pm 5\%$ tolerance, easily identified by its four-band color code: Yellow, Violet, Red for the 4.7k Ohm value, followed by a Gold band indicating the 5% tolerance.

The 4.7k Ohm resistor's versatility makes it invaluable. It's frequently employed as a pull-up resistor for digital input pins on microcontrollers (like Arduino or ESP32), ensuring a defined high logic state when a switch is open, or in I2C communication lines to provide reliable data transmission. It's also a common choice in voltage divider networks to scale down voltages for sensor inputs or biasing transistors. Furthermore, it can serve as a current limiting resistor in various circuits where a moderate current reduction is required. Its standard axial-leaded format ensures easy integration into breadboards, perfboards, and through-hole PCBs, making the 4.7k Ohm ¼ Watt Carbon Film Resistor an indispensable component for prototyping, experimentation, and final circuit assembly in almost any electronics endeavor.

The 4.7kΩ Resistor is a commonly used standard E12-series value resistor, essential for both analog and digital circuits. It offers a great balance between power and sensitivity, making it perfect for sensor interfaces, pull-up resistors, and voltage dividers in Arduino, ESP32, and Raspberry Pi projects.

Its carbon film composition and axial design allow easy installation in breadboards, PCBs, and DIY prototyping boards. The yellow-violet-red-gold color band makes it easily identifiable.
