68 µF, 25 V, 900 mOhm ESR — TAJ series molded tantalum
The TAJV686K025RNJ is a KYOCERA AVX TAJ series molded tantalum capacitor rated at 68 µF and 25 V with ±10% tolerance. Its 900 mOhm ESR at 25 V makes it a solid choice for bulk decoupling on 3.3 V and 5 V rails where ripple current handling and output stability matter — the ESR directly sets the self-heating and the voltage ripple under load. The 2924 (7361 Metric) case size is a standard large tantalum footprint; the 3.75 mm seated height fits typical board stack-ups without clearance issues.
TAJV686K025RNJ carries an active product status from KYOCERA AVX.
That means it holds its capacitance and ESR across avionics cold-soak, downhole heat, and satellite thermal cycling — environments where commercial-grade tantalums would derate or fail.
General-purpose molded construction
Molded case construction with general-purpose features — no low-ESR or high-reliability screening, but the standard TAJ series is widely used in power-supply bypass, DC-DC converter output filtering, and energy-storage applications where a solid tantalum is preferred over aluminum electrolytic for size and stability.
