• The 680K Ohm 684 1206 SMD Resistor is an ultra-high-value precision resistor engineered for the most demanding low-power and high-impedance applications. With 680,000 ohms resistance and tight ±1% tolerance, it is perfect for ultra-high-impedance voltage dividers (ultra-low-power battery voltage monitoring, extremely high-resistance sensor scaling, ADC input conditioning with virtually no loading), near-zero-current pull-up/pull-down networks, feedback resistors in ultra-high-gain op-amp stages, RC timing and oscillator circuits with exceptionally long time constants, bias networks in ultra-low-power amplifiers, and various other energy-critical analog, mixed-signal, and microcontroller applications where minimizing current draw is essential.
• Rated at 1/4W (0.25W) power dissipation, it generates essentially no heat in ultra-low-current circuits, making it ideal for battery-operated devices, wearables, remote sensors, energy-harvesting systems, long-life portable instrumentation, and any design where power efficiency is the top priority.
• The 1206 package size remains highly popular for its excellent balance between compactness for dense modern boards and ease of reliable soldering — both automated and manual. Commonly used in advanced portable devices, industrial ultra-low-power sensors, high-impedance audio circuits, IoT ultra-low-power nodes, sophisticated battery management systems, Arduino, Raspberry Pi, ESP32 ultra-low-power projects, and professional energy-efficient PCB manufacturing.
• Built with thick film technology, it delivers exceptionally low temperature drift, negligible excess noise, and superior long-term stability. The “684” marking follows the standard 3-digit SMD code: 68 × 10⁴ = 680,000 Ohms. Fully RoHS compliant and optimized for lead-free reflow soldering processes.A critical ultra-high-value component for every ultra-low-power or precision analog-focused inventory—this 680KΩ 1% 1206 SMD resistor provides top-tier accuracy, near-zero power impact, and excellent value. Available in bulk reels for production or small packs for makers, developers, and repair work.
