The 0805 footprint and 1.20 mm seated height fit dense PCB layouts where board real estate is at a premium — typical for decoupling on mixed-signal boards, power rail filtering in portable equipment, or timing circuits in industrial controls. With a 20 Ohm ESR, this part handles moderate ripple current without excessive self-heating; the ESR is a key parameter when stacking the error budget in a power supply decoupling application — higher ESR means more voltage ripple under load transients. The molded construction provides mechanical robustness and moisture resistance across the full temperature sweep, reducing the risk of parametric drift in field-deployed systems. ## Tape & Reel delivery for automated assembly The 0805 package is a standard EIA size, so existing feeder setups and nozzle kits on most placement machines will handle it without changeover.","metaTitle":"TAJR684M020RNJ KYOCERA AVX Molded Tantalum Capacitor 0.68","metaDescription":"TAJR684M020RNJ from KYOCERA AVX: Molded tantalum capacitor, 0.68 µF, 20 V, ±20%, 0805, -55°C to 125°C, 20 Ohm ESR.
