Product Description The 220 Ohm 1/4 Watt Resistor is a fundamental passive component, widely recognized as the standard current-limiter for 5V LED circuits. These resistors feature a 5% tolerance, ensuring reliable performance for general-purpose prototyping and digital logic. With a 0.25W power rating, they provide a stable resistive barrier, preventing overcurrent damage to sensitive semiconductors while maintaining a compact axial form factor.

Key Features

  • LED Circuit Standard: Optimized for driving standard 5mm LEDs from a 5V supply (like Arduino) at a safe ~15-20mA.

  • Axial Through-Hole Leads: Flexible, tin-plated leads ensure a secure fit in solderless breadboards and easy soldering.

  • 4-Band Color Code: Clearly marked with Red, Red, Brown, Gold for instant manual identification and sorting.

  • Stable Carbon Film Tech: Provides consistent electrical performance with low electrical noise and high thermal stability.

  • Safety Coating: Finished with a flame-retardant lacquer to protect the element from moisture and prevent combustion during overloads.

Technical Details

  • Maximum Working Voltage: Rated for stable operation up to 250V in standard DC/AC circuit environments.

  • Overload Surge Voltage: Capable of withstanding short-duration peak surges up to 500V without failure.

  • Operating Temperature: Functions accurately within a wide thermal range of -55°C to +155°C.

  • Temperature Coefficient: Typically rated at ±450 ppm/°C, ensuring minimal resistance drift during operation.

  • Dielectric Strength: Offers high insulation protection up to 500V AC between the resistive element and surroundings.

  • Lead Material: Solder-plated copper-clad steel leads for superior conductivity and reliable mechanical strength.

  • Resistance Stability: Engineered to stay within ±3% of the nominal value even after 1,000 hours of rated load.

  • Compact Body Size: Miniature axial dimensions (approx. 2.3mm diameter) allow for high-density PCB layouts.

  • Environmental Standards: Fully RoHS compliant and lead-free for modern electronic assembly requirements.

  • Low Parasitic Inductance: Suitable for high-speed signal paths and basic RF filtering applications.

  • Moisture Protection: Sealed with multiple epoxy layers to prevent oxidation of the carbon element in humid conditions.

  • Audio-Grade Performance: Low current-noise characteristics make it suitable for basic audio signal conditioning.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: In 9V battery projects, a 220 Ohm resistor is ideal for powering high-brightness LEDs, providing roughly 30-35mA of current (ensure your LED is rated for high current).

  • 18650 Monitoring: Use as a pull-up or pull-down resistor in 18650 cell protection circuits to ensure MOSFET gates are held at a stable logic level.

  • IC Protection: Perfect for limiting current to the base of NPN transistors like the BC547 or as a series resistor for protecting microcontroller I/O pins from short circuits.

  • Related Products: We recommend pairing these with our Half-Size Breadboards and 22 AWG Jumper Wires.

Package Includes
