Product Description: The 150k Ohm 1/4 Watt Resistor is a high-impedance passive component designed for precise signal management and current control. These carbon film resistors feature a 5% tolerance, ensuring reliable performance in analogue and digital timing circuits. With a standard 0.25W power rating, they are an ideal choice for creating voltage dividers, setting transistor bias points, and serving as pull-up/pull-down resistors in low-power electronic designs.

Key Features

  • High Resistance Value: Perfect for applications requiring minimal current flow in high-impedance signal paths.

  • Axial Through-Hole Leads: Standard flexible leads ensure a secure fit in breadboards and easy soldering on prototyping PCBs.

  • Standard Colour Coding: Features the 4-band colour code (Brown, Green, Yellow, Gold) for rapid manual identification.

  • Stable Carbon Film Construction: Offers high reliability with low electrical noise for clean signal transmission.

  • Flame Retardant Coating: Includes a protective lacquer layer to enhance safety and provide environmental resistance.

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: Provides 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 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.

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

  • 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.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: In 9V battery projects, a 150k Ohm resistor is an excellent choice for a pull-up to keep input pins high while drawing only ~60µA, significantly extending battery life.

  • 18650 Monitoring: Use two of these resistors in a voltage divider network to monitor 18650 cell levels with high-impedance inputs, keeping parasitic drain extremely low.

  • IC & MOSFET Support: Ideal for discharging the gate of Power MOSFETs or as a timing component in 555 Timer circuits for long-duration pulses.

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