Product Description The 2.2M Ohm 1/4 Watt Resistor is an ultra-high resistance passive component designed for applications requiring extremely low current flow. These carbon film resistors are essential for high-gain amplifier biasing, long-period timing circuits, and high-impedance voltage sensing. With a 5% tolerance and standard 0.25W power rating, they provide stable and reliable performance in both sensitive analog and low-power digital environments.

Key Features

  • Ultra-High Impedance: Perfect for circuits where minimizing current draw is critical to battery life or signal integrity.

  • Carbon Film Stability: Engineered for low electrical noise, making it ideal for high-impedance input stages.

  • Breadboard Compatible: Standard axial leads allow for seamless integration into solderless breadboards.

  • Manual Identification: Features clear 4-band color coding (Red, Red, Green, Gold) for easy value verification.

  • Flame-Retardant Coating: Coated with a protective lacquer to ensure safety and durability under thermal stress.

Technical Details

  • Maximum Working Voltage: Rated for continuous operation up to 250V AC/DC.

  • Overload Capacity: Capable of handling short-duration surge voltages up to 500V.

  • Operating Temperature: Maintains rated accuracy from -55°C to +155°C.

  • Temperature Coefficient: Typically rated at ±450 ppm/°C for thermal stability.

  • Dielectric Strength: Offers high insulation protection up to 500V AC.

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

  • Resistance Drift: Guaranteed to stay within ±3% of the nominal value after 1,000 hours of continuous load.

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

  • RoHS Compliant: Manufactured using lead-free processes to meet global environmental standards.

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

  • High Frequency Performance: Low parasitic capacitance makes it suitable for high-impedance signal conditioning.

  • Standard Precision: Class J (±5%) offers a cost-effective solution for non-precision timing and biasing.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: In 9V battery applications, a 2.2M resistor draws a negligible ~4µA, making it the ultimate choice for "always-on" pull-up pins.

  • 18650 Monitoring: Use this in an ultra-low-power voltage divider for monitoring 18650 cell levels to eliminate parasitic drain during deep-sleep modes.

  • IC & MOSFET Support: Ideal for providing a high-impedance discharge path for the gate of a Power MOSFET or as a timing resistor in low-frequency 555 Timer circuits.

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

Package Includes

  • 5 x 2.2M Ohm 1/4 Watt Carbon Film Resistors.
