All About ResistorsProduct Overview
Nothing stops a project dead in its tracks faster than not having the right resistor. These components are arguably the most fundamental and essential passive components in all of electronics. They are the "control" in your circuits; you use them to limit current for LEDs, create voltage dividers to read sensors, pull-up or pull-down digital pins, and build filters.
The Essential Resistor Library
The SparkFun Resistor Kit is an absolute must-have for any prototyping station. This curated library provides 500 total 1/4-watt resistors, giving you 25 pieces each of the 20 most common and useful standard values. Instead of digging through messy bins or halting a build to order parts, this assortment ensures you have the exact component you need right at your fingertips. Whether you are limiting current to a simple LED or pulling a microcontroller pin high or low, this kit covers the baseline hardware requirements for almost any low-power embedded project.
Breadboard Ready Assortment
These 1/4W resistors are the perfect size for standard prototyping. They're easy to handle, their color bands are highly visible for quick identification, and their leads fit perfectly into breadboard contacts without bending or breaking. To give you the right tool for any job, the assortment covers a massive range of resistances:
- 0Ω to 47Ω: Ideal for wire jumpers and specialized current sensing.
- 100Ω to 680Ω: Perfect for protecting standard LEDs and basic circuitry.
- 1kΩ to 10kΩ: Standard values for digital pins, switches, and communication lines.
- 22kΩ to 1MΩ: Used for precise voltage dividers, timing circuits, and advanced filtering.
This kit is an essential companion to our SparkFun Beginner Parts Kit (which does not include resistors), or pair it with our SparkFun Capacitor Kit to build a comprehensive, well-rounded parts library.
Keeping this comprehensive kit on your desk ensures you'll always be ready to tackle your next circuit design without any delays!
