Product Description The 470k Ohm 1/4 Watt Resistor is a high-resistance passive component designed for precise signal biasing and ultra-low current control. These carbon film resistors feature a 5% tolerance, making them ideal for high-impedance analog circuits, timing networks, and amplifier input stages. With a standard 0.25W power rating, they provide stable performance in a compact axial package, suitable for both professional engineering and hobbyist prototyping.

Key Features

  • High Impedance Utility: Optimized for applications requiring minimal current draw in sensitive signal paths.

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

  • Breadboard Compatible: Standard axial leads fit perfectly into solderless breadboards and universal PCBs.

  • Manual Identification: Features clear 4-band color coding (Yellow, Violet, Yellow, Gold) for rapid 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 stable operation up to 250V AC/DC in standard environments.

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

  • Dielectric Strength: Provides high insulation protection up to 500V AC between the resistive element and the surroundings.

  • Operating Temperature: Maintains rated accuracy across a wide thermal range of -55°C to +155°C.

  • Temperature Coefficient: Typically rated at ±450 ppm/°C, ensuring minimal resistance drift during operation.

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

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

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

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

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

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

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

  • High Insulation Resistance: Designed to prevent leakage current in high-voltage sensing applications.

  • Thermal Dissipation: Axial design allows for effective heat convection in open-air circuit environments.

  • Indefinite Shelf Life: Protective coating ensures the leads and element remain viable for long-term storage.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: In 9V battery applications, a 470k resistor draws a negligible ~19µA, making it an excellent choice for pull-up pins to maximize battery longevity.

  • 18650 Monitoring: Use this in a high-impedance voltage divider for monitoring 18650 cell levels to eliminate parasitic battery drain during long-term storage or 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 component in long-duration 555 Timer circuits.
