Molded tantalum construction and board fit
The molded epoxy case provides mechanical protection and moisture resistance, suitable for reflow soldering without the cracking risk of some ceramic MLCCs. Rated at 6.8 µF with ±10% tolerance and a 25 V DC voltage rating, this part fits bulk decoupling on 12 V or 5 V rails, hold-up capacitors in power supplies, and output filtering in low-dropout regulators. The 2 Ohm ESR at 100 kHz limits ripple current capacity — expect around 300 mA ripple current at 85°C, derating further at higher ambient.
The voltage derating curve in the TAJ series datasheet recommends staying below 2/3 of rated voltage above 85°C to maintain reliability.
No direct pin-compatible replacement is listed — the TAJ series covers a range of capacitance and voltage combinations, but each size code (C case) and rating is a distinct order code.
