The UKA0J103MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKA series designed for high-grade audio equipment and applications requiring robust bulk capacitance. It delivers 10,000 µF at 6.3 V in a compact φ12.5×40 mm can with a wide operating temperature range and proven endurance.

This component is targeted at audio system designers and embedded engineers who need high capacitance, elevated ripple-handling capability, and reliable operation across –55 °C to 105 °C.

Key Features

• Capacitance & Tolerance – 10,000 µF nominal with ±20% tolerance (measured at 120 Hz, 20 °C).
• Rated Voltage – 6.3 V DC nominal rating suitable for low-voltage audio and analog power rails.
• Ripple Current Performance – Low-frequency ripple current: 1,650 mA (120 Hz); high-frequency ripple current: 1,897.5 mA (10 kHz), supporting demanding ripple conditions.
• Leakage Current & Endurance – Specified leakage current of 1,890 µA and endurance rated for 2,000 hours at 105 °C with defined post-test limits.
• Wide Temperature Range – Operational from –55 °C to 105 °C, enabling use in systems exposed to broad thermal conditions.
• Mechanical & Mounting – Radial lead can package with 5 mm lead spacing (±0.5 mm tolerance) and physical size φ12.5 × 40 mm (approximately 4.0 × 1.25 cm).
• Packaging & Production – Available in bulk (no terminal forming) or bag packing; product status: mass production.
• Qualification – Rated to AEC‑Q200, supporting designs that require component-level reliability qualifications.

Typical Applications

• High‑Grade Audio Equipment – Bulk capacitance and ripple handling for power supply smoothing and decoupling in professional audio amplifiers and preamplifiers.
• Audio Power Supplies – Use in low-voltage audio power rails where large capacitance and high ripple current capability reduce noise and maintain stable supply under load.
• Analog and Mixed‑Signal Systems – Energy storage and decoupling for analog sections in consumer and pro audio electronics operating across wide temperature ranges.

Unique Advantages

• High Bulk Capacitance in a Compact Can – 10,000 µF in a φ12.5×40 mm package reduces board area while providing the capacitance required by demanding audio circuits.
• Robust Ripple Handling – Specified low- and high-frequency ripple currents enable reliable operation under continuous ripple loading common in audio power supplies.
• Wide Thermal Endurance – Rated for operation from –55 °C to 105 °C and endurance of 2,000 hours at 105 °C for consistent performance in thermally challenging environments.
• AEC‑Q200 Rated – Component-level qualification that assists system designers targeting higher reliability specifications.
• Through‑Hole Mounting Simplicity – Radial lead configuration with standard 5 mm spacing simplifies prototyping and through-hole assembly processes.
• Production‑Ready Packaging – Available in bulk and bag formats and currently in mass production to support volume builds.
