Product Description The 1M Ohm 1/4 Watt Resistor is a high-resistance passive component essential for timing, biasing, and high-impedance signal conditioning. These carbon film resistors feature a 5% tolerance, ensuring reliable performance in analog and digital circuits. With a standard 0.25W power rating, they are the go-to choice for applications requiring minimal current draw, such as pull-up resistors for low-power microcontrollers or as part of long-duration RC timing networks.

Key Features

  • Ultra-Low Current Draw: Ideal for high-impedance sensing and battery-powered logic where efficiency is critical.

  • Stable Carbon Film Construction: Offers high reliability with low electrical noise and consistent resistance.

  • Breadboard Friendly: Standard axial leads fit perfectly into solderless breadboards and prototyping PCBs.

  • Instant Identification: Clearly marked with a 4-band color code (Brown, Black, Green, Gold) for rapid sorting.

  • Safety Coating: Finished with a flame-retardant lacquer to prevent damage during minor electrical stress.

Technical Details

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

  • Maximum Overload Voltage: Capable of withstanding short-duration peak surges up to 500V.

  • Dielectric Withstanding Voltage: Provides insulation protection up to 500V AC.

  • Operating Temperature Range: Reliable performance maintained from -55°C to +155°C.

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

  • Lead Quality: Tin-plated copper-clad steel leads for superior conductivity and strong mechanical joints.

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

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

  • Moisture Resistance: Sealed with multi-layer epoxy to prevent oxidation of the carbon element in humid conditions.

  • Low Parasitic Capacitance: Suitable for high-impedance inputs without significantly affecting signal speed.

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

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

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: In 9V battery projects, a 1M resistor is the perfect "keep-alive" pull-up, drawing only ~9µA, ensuring your battery lasts as long as possible.

  • 18650 Monitoring: Use this in an ultra-high impedance voltage divider for monitoring 18650 cell voltages to prevent parasitic battery drain during deep sleep.

  • IC & Sensor Support: Essential for high-gain op-amp circuits or to provide a discharge path for the gate of a Power MOSFET.

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

Package Includes

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