Product Description: The 15k Ohm 1/4 Watt Resistor is a reliable passive component designed for precise current regulation and signal biasing. These carbon film resistors feature a 5% tolerance, ensuring consistent performance for general-purpose electronic applications. With a standard 0.25W power rating, they are ideal for pull-up/pull-down networks, RC timing circuits, and setting transistor bias points in both hobbyist and professional projects.

Key Features

  • Optimised for Signal Biasing: Frequently used to set the operating point of transistors or as part of a voltage divider.

  • Axial Through-Hole Design: Long, flexible leads ensure easy installation on breadboards or permanent PCBs.

  • Quick Identification: Features the standard 4-band color code (Brown, Green, Orange, Gold) for rapid manual sorting.

  • Low Noise Performance: Carbon film construction minimizes electrical noise, making it suitable for sensitive analog paths.

  • Protective Coating: Finished with a flame-retardant lacquer to provide environmental protection and prevent combustion during overloads.

Technical Details

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

  • Overload Surge Capacity: Can withstand temporary peak voltages up to 500V for short durations.

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

  • Operating Temperature: Maintains accurate resistance values within a range of -55°C to +155°C.

  • Temperature Coefficient: Typically rated at ±450 ppm/°C, ensuring thermal stability during continuous operation.

  • Lead Material: Solder-plated copper-clad steel leads for high conductivity and excellent solder wetting.

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

  • Miniature Body Size: Compact axial dimensions (approx. 2.3mm x 6.5mm) for high-density component layouts.

  • Environmental Compliance: Fully RoHS compliant and lead-free for modern manufacturing standards.

  • High Frequency Response: Low parasitic inductance makes it suitable for high-speed logic and basic RF filtering.

  • Precision Grade: Class J (±5%) provides a cost-effective balance for most hobbyist and commercial projects.

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

  • Solderability: Meets standard industrial requirements for both manual and wave soldering processes.

  • Reliability: Designed to fail open-circuit during extreme overloads rather than shorting.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: In 9V battery projects, a 15k Ohm resistor is an excellent choice for a pull-up to keep input pins high while drawing only ~0.6mA, effectively saving battery life.

  • 18650 Monitoring: Use two of these resistors in series to create a simple voltage divider for monitoring 18650 cell levels with a 3.3V or 5V microcontroller ADC.

  • IC & Driver Support: Ideal for limiting current to the base of NPN transistors like the BC547 when switching low-power loads like buzzers or small relays.

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