Product Description: The 1k Ohm 1/4 Watt Resistor is one of the most widely used passive components in electronics, serving as a standard for current limiting and signal biasing. These resistors feature a 5% tolerance, ensuring reliable performance for general-purpose applications. With a standard 0.25W power rating, they are the go-to choice for pull-up/pull-down logic, LED protection in 5V-12V circuits, and as base resistors for transistors.

Key Features

  • Universal Application: The "bread-and-butter" value for digital logic and analog prototyping.

  • Axial Through-Hole Leads: Flexible leads allow for easy insertion into breadboards or soldering on PCBs.

  • Standard Color Coding: Features the 4-band color code (Brown, Black, Red, Gold) for rapid manual identification.

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

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

  • 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.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: In 9V battery projects, a 1k Ohm resistor is the perfect "safe" resistor to use for indicator LEDs, limiting current to a conservative ~7-9mA to prolong battery life.

  • 18650 Monitoring: Use two 1k resistors as part of a voltage divider for monitoring 18650 cell levels; however, consider higher values (like 10k or 100k) if you need to minimize parasitic drain.

  • IC & Driver Support: Ideal for use as a pull-up resistor on I2C lines or to protect the input pins of an Arduino or ESP32 from floating signals.

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

Package Includes

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