UKL0J103MHD

The UKL0J103MHD is a Nichicon UKL series aluminum electrolytic capacitor in a radial‑lead can, offering 10,000 µF capacitance at a 6.3 V rating. Designed for low leakage and high ripple handling, this through‑hole component is targeted at applications such as audio where bulk energy storage and smoothing are required.

Key electrical characteristics include low leakage current and the ability to handle significant ripple at both low and high frequencies. Note: this part is designated End Of Life and the UKL series documentation indicates products in the series are scheduled to be discontinued.

Key Features

• High Capacitance: 10,000 µF nominal capacitance provides substantial bulk energy storage for power smoothing and decoupling.
• Rated Voltage: 6.3 V working voltage suitable for low‑voltage power rails and audio circuits.
• Low Leakage Current: Specified leakage current of 126 µA supports low standby losses in DC applications.
• Ripple Current Capability: Low‑frequency ripple current of 1.9 A at 120 Hz and high‑frequency ripple current of 2.185 A at 10 kHz enable reliable performance under dynamic load conditions.
• Endurance: Rated for 2000 hours at 85 °C, with endurance characteristics specified after restoration to 20 °C.
• Radial Through‑Hole Package: φ18 × 40 mm can with 7.5 mm lead spacing (±0.5 mm) and radial leads simplifies board-level assembly and replacement.
• Temperature Range: Operates from −40 °C to 85 °C for typical ambient and enclosure conditions.
• Polarized Electrolytic: Standard polarized aluminum electrolytic construction for bulk smoothing and energy storage applications.

Typical Applications

• Audio circuits: Bulk smoothing and power supply decoupling for audio amplifiers and preamplifiers where large capacitance and low leakage are required.

Unique Advantages

• Large energy storage in compact can: 10,000 µF in a φ18 × 40 mm radial can delivers substantial capacitance density for power rail stabilization without custom assemblies.
• Low standby loss: Measured leakage current of 126 µA helps minimize quiescent power draw in low‑power systems.
• Broad ripple handling: Specified ripple current at both 120 Hz (1.9 A) and 10 kHz (2.185 A) supports use in systems with mixed-frequency load swings.
• Through‑hole robustness: Radial lead, can package with defined lead spacing eases prototyping, repairability, and mechanical stability in product enclosures.
• Qualified endurance window: 2000 hours at 85 °C provides predictable lifetime performance for designs with elevated operating temperatures.
