UKA0J221MED

The UKA0J221MED from Nichicon is a miniature, radial‑lead aluminum electrolytic capacitor in the UKA series designed for audio equipment. It provides 220 µF capacitance at a 6.3 V rating in a compact φ6.3 × 11 mm can, delivering stable performance across a wide temperature range.

Targeted at high‑grade audio applications, this polarized capacitor combines a low loss tangent, rated ripple current capabilities at low and high frequencies, and long endurance for demanding operating environments.

Key Features

• Electrical Performance 220 µF capacitance at 6.3 V with a tolerance of −20% to +20% and a dissipation factor (tanδ) of 0.30 (measured at 20°C, 120 Hz).
• Ripple Current Capability Low‑frequency ripple current: 160 mA (120 Hz); High‑frequency ripple current: 240 mA (10 kHz), supporting AC stress in audio circuitry.
• Leakage Current Specified leakage current of 41.58 µA (measured conditions per product data), suitable for stable bias conditions in precision audio paths.
• Reliability & Endurance Designed for 2,000 hours at 105°C with specified limits on capacitance change, tanδ, and leakage current after the endurance test.
• Wide Temperature Range Rated to operate from −55°C to +105°C, providing stability across extended environmental conditions encountered in audio equipment.
• Compact Radial Package φ6.3 × 11 mm can with 2.5 mm lead spacing (±0.5 mm) in a radial‑lead mounting style; available in bulk/no terminal forming or bag packing.
• Industry Qualification UKA series parts carry an AEC‑Q200 rating as noted in the part specifications.

Typical Applications

• High‑Grade Audio Equipment — Compact polarized capacitance for audio devices within the UKA series where space and audio performance are considerations.
• Audio Power Supply Modules — Suitable for localized energy storage and AC ripple handling in audio power sections, leveraging specified ripple current and endurance.
• Compact Consumer Audio Electronics — Small form factor (φ6.3 × 11 mm) radial can useful where board space and radial lead mounting are required.

Unique Advantages

• Miniature footprint: A φ6.3 × 11 mm can offers high capacitance in a compact radial package for space‑constrained audio designs.
• Measured low loss (tanδ): tanδ = 0.30 at 6.3 V (20°C, 120 Hz) supports low dissipation in audio signal environments.
• Frequency‑rated ripple capability: Defined ripple current values at both 120 Hz and 10 kHz give designers predictable thermal and AC performance.
• Extended temperature operation: −55°C to +105°C rating supports stable operation across broad environmental ranges.
• Long endurance specification: 2,000 hours at 105°C with defined post‑test limits on capacitance, tanδ, and leakage current for lifecycle planning.
• Radial lead and packaging options: Radial mounting with 2.5 mm lead spacing and bulk or bag packing options streamline assembly and inventory choices.
