0.68 µF, 20 V, 0805 — Molded tantalum for tight board budgets
The TAJR684M020RNJ: This is a KYOCERA AVX TAJ series molded tantalum capacitor, delivering 0.68 µF capacitance with ±20% tolerance at 20 V rated voltage in a compact 0805 (2012 Metric) surface-mount package. 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.
