UKA0J332MHD

The UKA0J332MHD is a Nichicon UKA series aluminum electrolytic capacitor in a radial lead can designed for audio applications. It delivers 3.3 mF capacitance at a 6.3 V rating in a compact φ12.5 × 20 mm package with 5 mm lead spacing.

Engineered for reliability in demanding environments, this part offers a wide operating temperature range (−55°C to 105°C), specified ripple-current performance at both low and high frequencies, and a 2000 hour endurance rating at 105°C.

Key Features

• High Capacitance in Compact Can — 3.3 mF (3300 µF) at 6.3 V in a φ12.5 × 20 mm radial can provides bulk energy storage in a small footprint.
• Wide Operating Temperature — Rated from −55°C to 105°C for designs that require extended temperature tolerance.
• Ripple Current Performance — Low-frequency ripple current of 910 mA (120 Hz) and high-frequency ripple current of 1.0465 A (10 kHz) for robust AC handling in power rails and audio circuits.
• Leakage Current Specified — Leakage current listed as 623.7 µA for predictable bias behavior in sensitive circuits.
• Long Endurance — 2000 hours life at 105°C, with endurance characteristics defined by the UKA series specification.
• Radial Lead Package — Through-hole radial lead mounting with 5 mm lead spacing (±0.5 mm) for easy PCB placement and assembly.
• Quality Rating — AEC-Q200 listed in product specifications.
• Packaging & Availability — Available in bulk (no terminal forming) and bag packing; status: mass production.

Typical Applications

• High-grade Audio Equipment — Intended for use in premium audio designs where the UKA series is specified for audio performance and stability across a wide temperature range.
• Audio System Power Sections — Suited to audio power rails requiring 3.3 mF capacitance and defined ripple-current handling at both 120 Hz and 10 kHz.
• Through-hole PCB Audio Modules — Compact radial can and 5 mm lead spacing make this part suitable for through-hole audio boards and module assemblies.

Unique Advantages

• Compact energy density: 3.3 mF in a φ12.5 × 20 mm can minimizes board area while providing substantial bulk capacitance.
• Wide temperature and long-life performance: −55°C to 105°C rating with 2000 hours endurance at 105°C supports reliability in thermally demanding audio equipment.
• Dual-frequency ripple capability: Specified ripple currents at 120 Hz (910 mA) and 10 kHz (1.0465 A) allow confident selection for both power-line smoothing and higher-frequency decoupling in audio circuits.
• Predictable leakage behavior: Leakage current specified (623.7 µA) for predictable bias and low-noise designs.
• Automotive-grade qualification: AEC-Q200 listing provides an added level of component qualification where that rating is required.
• Through-hole convenience: Radial lead form and standard 5 mm lead spacing simplify prototyping and serviceability on audio PCBs.
