• The 680K Ohm (684) 0805 SMD Resistor is a mega-high value precision resistor engineered for the most critical ultra-high-impedance and ultra-low-current applications in modern precision electronics. With ±5% tolerance and a conservative 1/8W power rating, it serves as the core element in ultra-high-impedance voltage divider networks for precision analog sensor front-ends, high-accuracy ADC signal conditioning, ultra-low-noise reference voltage generation, picoammeter input protection, electrometer-grade current measurement, and any circuit where input bias currents must be restricted to the picoampere or femtoampere domain. It is also the preferred choice for ultra-low-leakage pull-up/pull-down resistors in high-impedance digital sensor interfaces, nanowatt-class or deep-sleep microcontroller GPIO configurations, specialized open-drain setups in battery-powered scientific instrumentation, and any mixed-signal or digital circuit where leakage must be minimized to extreme levels to preserve signal integrity or extend battery life. Additionally, it performs exceptionally as the high-resistance component in transimpedance amplifiers with pico/femtoampere resolution, feedback networks in ultra-low-power op-amps, leakage current monitoring in high-voltage insulation testers, guard-ring biasing in pico-level measurement systems, and the most sensitive analog signal paths found in scientific, medical, and industrial precision instruments.
• The thick film process achieves world-class insulation resistance in the teraohm range, leakage currents in the picoampere to femtoampere domain, vanishingly low parasitic capacitance and inductance, negligible voltage and temperature coefficients at mega-ohm levels, ultra-low thermal and current noise, and outstanding long-term stability against humidity, voltage stress, temperature cycling, and aging—making the 680K 0805 an indispensable component in high-accuracy scientific instrumentation, medical diagnostic & therapeutic devices, radiation & particle detectors, ultra-low-power environmental monitoring nodes, precision electrometers, femtoampere current sources, and any application where resistance values in the high hundreds of kilo-ohms must remain exceptionally accurate and virtually drift-free over years of operation in demanding environmental conditions.
• The compact 0805 footprint maintains excellent electrical isolation even at 680kΩ while providing reliable thermal behavior for its power class and strong soldering integrity, enabling seamless use in both ultra-dense high-reliability production PCBs and individual laboratory-grade ultra-precision prototypes.
• Fully RoHS compliant and manufactured under the most rigorous high-value resistor process controls with special focus on leakage, drift, noise, and stability at mega-ohm levels, the 680K 0805 is one of the most trusted, highest-performance mega-ohm resistors available—delivering unmatched precision, ultra-low leakage, and rock-solid long-term accuracy for the most critical ultra-high-impedance and ultra-precision analog measurement and control applications.
