UKT1E682MHD

The UKT1E682MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UKT series, specified at 6800 µF (6.8 mF) and 25 V. It is designed for general audio equipment and other applications that benefit from high capacitance, robust ripple-current capability, and wide operating temperature range.

Key attributes include a wide temperature range of −55°C to 105°C, a rated endurance of 1000 hours at 105°C, AEC-Q200 qualification, and radial can packaging (φ18 × 35.5 mm) with 7.5 mm lead spacing—features that make it suitable for demanding power-filtering and decoupling roles in audio and qualified electronic systems.

Key Features

• High Capacitance & Rated Voltage — 6.8 mF (6800 µF) nominal capacitance at a rated voltage of 25 V with ±20% tolerance.
• Wide Temperature Range — Operates from −55°C to 105°C, supporting applications that require extended ambient capability.
• Endurance at Elevated Temperature — Rated life of 1000 hours at 105°C, with specified recovery performance after endurance testing.
• Ripple Current Performance — Low-frequency ripple current of 2.04 A at 120 Hz and high-frequency ripple current of 2.346 A at 10 kHz to support power-rail smoothing and dynamic load conditions.
• AEC-Q200 Qualification — Meets AEC-Q200 requirements for passive-component qualification as noted in the product specification.
• Radial Lead Package — φ18 × 35.5 mm radial can with 7.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for through-hole assembly.
• Polarized Electrolytic — Polar capacitor suited for DC power filtering and decoupling tasks; leakage current specified at 5100 µA.

Typical Applications

• Audio Equipment — Power-supply smoothing and decoupling in amplifiers and audio peripherals where sustained capacitance and ripple handling improve audible performance.
• Qualified Electronic Modules — Use in systems requiring AEC-Q200‑qualified passives for improved supply-chain and test reproducibility.
• Industrial Electronics — Power filtering and energy storage in assemblies operating across a wide temperature range (−55°C to 105°C).

Unique Advantages

• Substantial energy storage in a standard radial can — 6800 µF at 25 V provides notable bulk capacitance for power-rail stability in a φ18 × 35.5 mm package.
• Designed for high ripple environments — Rated ripple currents at both low and high frequencies reduce heating and extend service life under dynamic loads.
• Wide operating-temperature and endurance rating — −55°C to 105°C operation and 1000 hours at 105°C give designers predictable lifetime behavior in elevated-temperature applications.
• AEC-Q200 qualification — Facilitates inclusion in designs that require industry-standard passive-component qualification and traceable reliability practices.
• Through-hole, radial-lead form factor — 7.5 mm nominal lead spacing and standard can dimensions simplify PCB layout and assembly for legacy and robust designs.
