Capacitance and voltage rating for the BOM
The TAJE686K020RNJ: At 68 µF and 20 V rated, this TAJ-series tantalum capacitor covers the bulk decoupling sweet spot for 12 V rails and 5 V POL converters, with enough headroom for a 16 V bus. The ±10% tolerance keeps the filter corner frequency predictable across the reel. The 900 mOhm ESR sets the ripple current ceiling in a 2917 footprint.
It fits avionics black boxes, downhole instrumentation, and satellite power buses where the ambient cycles from cold-soak to hot bay. The molded case handles the thermal expansion without cracking.
No NRND or EOL notice — this part is suitable for new designs and existing BOM lines.
