UKA1A221MED

The UKA1A221MED is a miniature radial-lead aluminum electrolytic capacitor from Nichicon's UKA series designed for audio equipment. It offers 220 µF capacitance at a 10 V rating in a compact φ6.3 × 11 mm can with 2.5 mm lead spacing.

Engineered for demanding operating conditions, the part provides a wide temperature range (–55°C to 105°C), endurance of 2000 hours at 105°C, low leakage current (66 µA), and measurable ripple current capability—making it suitable where stable, low-noise decoupling is required. Status: End Of Life.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 10 V and tolerance of −20% to +20%.
• Audio-focused Series — Specified for audio equipment applications within the UKA series.
• Temperature Performance — Operating temperature range of −55°C to +105°C and endurance of 2000 hours at 105°C for long-term thermal stability.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) of 0.26 (measured at 20°C, 120 Hz) and leakage current of 66 µA as supplied in product data.
• Ripple Current Capability — Low-frequency ripple: 175 mA at 120 Hz; high-frequency ripple: 262.5 mA at 10 kHz, supporting power-filtering duties in audio circuits.
• Mechanical & Mounting — Radial lead, polarized aluminum can package, case size φ6.3 × 11 mm with lead spacing 2.5 mm (±0.5 mm).
• Qualification — Listed with AEC-Q200 in the product specifications.
• Packaging Options — Available in bulk (no terminal forming) or bag packing.

Typical Applications

• High‑grade Audio Equipment — Intended for use in audio equipment where compact, polarized electrolytic capacitors are required.
• Power Supply Decoupling — Provides local energy storage and ripple handling in low-voltage audio power rails.
• Signal and Analog Circuits — Suitable where low leakage and controlled tan δ are needed for stable analog/audio performance.

Unique Advantages

• Compact footprint: The φ6.3 × 11 mm can and 2.5 mm lead spacing allow tight placement on crowded PCBs.
• Wide temperature range: −55°C to +105°C supports operation across extended ambient and equipment temperature conditions.
• Endurance at elevated temperature: Rated for 2000 hours at 105°C, offering predictable aging behavior for design planning.
• Measured ripple performance: Specified ripple currents at both 120 Hz and 10 kHz let designers assess suitability for power-filtering in audio paths.
• Low leakage and controlled loss: 66 µA leakage and tan δ = 0.26 (120 Hz, 20°C) help minimize noise and DC offset concerns in sensitive circuits.
• Automotive-grade qualification listed: AEC‑Q200 appears in the specifications for use cases that reference that qualification.
