Product Description: The 1.2k Ohm 1/4 Watt Resistor is a precision passive component designed for reliable current regulation in electronic circuits. These carbon film resistors feature a 5% tolerance, ensuring consistent performance for general-purpose applications like pull-up/pull-down logic, signal conditioning, and timing. With a standard 0.25W power rating, they are a staple for breadboard prototyping and permanent PCB assembly in both hobbyist and professional projects.

Key Features

  • Optimised for 5V/12V Logic: Frequently used as a pull-up resistor for microcontrollers or as a current limiter for high-brightness LEDs.

  • Stable Carbon Film Tech: Provides excellent long-term stability with low electrical noise characteristics.

  • Axial Lead Format: Standard through-hole leads are compatible with all solderless breadboards and prototyping PCBs.

  • Clear Colour Coding: Marked with the 4-band colour code (Brown, Red, Red, Gold) for instant manual identification.

  • Protective Coating: Finished with a flame-retardant lacquer to ensure safety during minor circuit overloads.

Technical Details

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

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

  • Operating Temperature: Maintains rated resistance across a wide range from -55°C to +155°C.

  • Temperature Coefficient: Typically rated at ±450 ppm/°C, providing thermal stability during use.

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

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

  • Resistance Shift: Engineered to maintain values within ±3% even after 1,000 hours of continuous load.

  • Compact Body: Miniature size (approx. 2.3mm diameter) allows for high-density component placement.

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

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

  • Standard Tolerance: Class J (±5%), providing a cost-effective solution for non-precision analogue circuits.

  • Moisture Protection: Multiple epoxy layers prevent oxidation of the carbon element in humid conditions.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: In 9V battery projects, a 1.2k Ohm resistor is ideal for driving standard indicator LEDs, limiting current to approximately 6mA to save power.

  • 18650 Monitoring: Use this in a voltage divider network for 18650 cell monitoring to keep current leakage low while providing a readable signal to an ADC.

  • IC Protection: Perfect for limiting current to the base of NPN transistors like the BC547 when switching small relays or buzzers.

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

Package Includes

  • 5 x 1.2k Ohm 1/4 Watt Carbon Film Resistors.
