Product Description (Detailed):
Elevate your electronic projects with our reliable 330 Ohm Carbon Film Resistors, an indispensable component for a multitude of circuit designs. Often referred to simply as 330R resistors, these essential passive devices are engineered for consistent performance in a vast range of applications. Each resistor features a robust ¼ Watt (0.25W) power rating, making them perfectly suited for current limiting in LED circuits, pull-up/pull-down configurations, and signal conditioning in low-power electronic systems. The carbon film construction ensures stable resistance values with a common ±5% tolerance, clearly identifiable by the standard Orange-Orange-Brown-Gold color code bands. This construction provides a dependable and cost-effective solution for ensuring precise current control and voltage drops within your circuits.
Our axial lead through-hole resistors are designed for effortless integration into breadboards, prototyping boards, and printed circuit boards (PCBs), offering excellent mechanical stability for both temporary and permanent installations. With a typical maximum working voltage of 250V and an operational temperature range from approximately -55°C to +155°C, these resistors guarantee reliable operation across diverse environmental conditions. Whether you're building an Arduino circuit, interfacing with sensors, or designing a basic audio amplifier, the 330 Ohm carbon film resistor is a fundamental building block. It plays a critical role in controlling current according to Ohm's Law (I=V/R), protecting sensitive components, and ensuring the correct operational parameters for your design. Choose our high-quality 330 Ohm resistors for accuracy, durability, and a seamless experience in all your electronic endeavors.
The 330Ω Resistor is one of the most commonly used general-purpose resistors in DIY electronics and embedded system design. With a ¼ Watt power rating and 5% tolerance, it is ideal for limiting current to LEDs, protecting microcontroller GPIO pins, and creating simple voltage dividers.
Its compact axial through-hole design makes it easy to use with breadboards, PCBs, and perfboards, and its color code (orange-orange-brown-gold) allows for quick identification.
It’s a must-have for any Arduino, Raspberry Pi, or ESP32-based project, especially when working with LED indicators, sensors, and basic logic circuits.
