UKA0J472MHD

The UKA0J472MHD is a miniature radial‑lead aluminum electrolytic capacitor from Nichicon’s UKA series, specifically positioned for audio equipment. It delivers high bulk capacitance (4.7 mF / 4700 µF) in a compact φ12.5 × 25 mm can with a 6.3 V rated voltage.

Designed for demanding audio environments, this polarized capacitor combines wide operating temperature range (−55 °C to 105 °C), long endurance (2000 hours at 105 °C), and strong ripple handling to support stable power delivery in audio circuits and high‑grade audio equipment.

Key Features

• High Capacitance: 4700 µF (4.7 mF) provides substantial bulk energy storage for power supply smoothing and decoupling in audio systems.
• Rated Voltage: 6.3 V working voltage suitable for low‑voltage audio power rails and preamp stages.
• Wide Operating Temperature: −55 °C to 105 °C for reliable operation across harsh thermal conditions encountered in professional audio gear.
• Endurance: 2000 hours at 105 °C, meeting the series endurance specification for long‑term stability in continuous‑use applications.
• Ripple Current Capability: Low‑frequency ripple current 1.12 A (120 Hz) and high‑frequency ripple current 1.288 A (10 kHz), supporting demanding ripple conditions common in audio power supplies.
• Loss Characteristics: Tangent of loss angle (tan δ) specified as 0.36 (measured at 20 °C, 120 Hz) for this part, giving a clear parameter for design calculation.
• Leakage Current: Specified leakage current of 888.3 µA for predictable standby current and bias behavior.
• Compact Radial Package: φ12.5 × 25 mm can with 5 mm lead spacing (±0.5 mm) and radial lead mounting—easy to place on through‑hole PCBs and modules.
• Packaging & Production: Available in bulk (no terminal forming) or bag packing; part is in mass production.
• AEC‑Q200 Rated: Listed with AEC‑Q200 in the product specifications, reflecting qualification for demanding reliability applications.

Typical Applications

• High‑Grade Audio Equipment — Suited to audio amplifiers and high‑fidelity components where stable bulk capacitance and temperature tolerance matter.
• Audio Power Supplies — Bulk energy storage and smoothing on low‑voltage rails in preamplifiers, DAC/ADC power sections, and analog front ends.
• Embedded Audio Modules — Compact radial form factor makes it usable in modules and assemblies that require robust capacitance in a small footprint.

Unique Advantages

• High energy density in a compact can: 4700 µF in a φ12.5 × 25 mm package reduces board area compared with multiple smaller capacitors.
• Designed for audio workloads: UKA series focus on high‑grade audio equipment provides part‑level specs tuned for audio system use.
• Robust ripple handling: Rated ripple currents at both low and high frequencies allow designers to manage power supply ripple across the audio bandwidth.
• Wide temperature endurance: −55 °C to 105 °C and 2000‑hour endurance at 105 °C support long service life in thermally challenging installations.
• Industry qualification: AEC‑Q200 listing adds a recognized reliability benchmark for designers requiring qualified passive components.
• Through‑hole radial convenience: 5 mm lead spacing and standard radial can simplify replacement, prototyping, and module assembly.
