UKA0J220MDD

The UKA0J220MDD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKA series designed for audio applications. It delivers 22 µF capacitance at a rated voltage of 6.3 V in a compact φ5 × 11 mm can with 2 mm lead spacing.

This part combines a wide operating temperature range (−55 °C to 105 °C) and a 2000-hour endurance rating at 105 °C with characterized electrical parameters such as tan δ, leakage current, and ripple current to support stable performance in audio-focused designs.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with a rated voltage of 6.3 V and tolerance of −20% to +20%.
• Low-loss Characteristics — Tangent of loss angle (tan δ) specified at 0.30 (measured at 20 °C, 120 Hz) to help maintain signal integrity in audio circuits.
• Leakage Current — Measured leakage current of 4.158 µA supporting predictable bias conditions in sensitive circuits.
• Ripple Current Handling — Rated ripple current of 45 mA at 120 Hz (low frequency) and 90 mA at 10 kHz (high frequency) for decoupling and filtering tasks across frequency ranges.
• Temperature & Endurance — Operates from −55 °C to 105 °C with an endurance rating of 2000 hours at 105 °C per the series specification.
• Package & Mounting — Radial can package, φ5 × 11 mm size, 2 mm lead spacing, supplied in bulk (no terminal forming) or bag packing for through-hole assembly.
• AEC-Q200 Rated — Series includes AEC-Q200 rating noted in specifications.

Typical Applications

• High-grade audio equipment — Suited to audio designs that require stable capacitance and controlled dissipation across a wide temperature range.
• Audio amplifiers and preamplifiers — Component parameters such as tan δ (0.30) and low leakage current support consistent performance in sensitive amplifier stages.
• Audio signal decoupling and filtering — Ripple current ratings at 120 Hz and 10 kHz make the part appropriate for smoothing and decoupling in audio power rails and circuits.

Unique Advantages

• Compact radial footprint: φ5 × 11 mm can and 2 mm lead spacing enable tight board layouts for through-hole audio assemblies.
• Wide ambient tolerance: −55 °C to 105 °C operating range supports reliable operation across varied environmental conditions.
• Endurance at elevated temperature: 2000-hour rating at 105 °C provides predictable long-term behavior for thermal-stressed designs.
• Frequency-aware ripple performance: Separate ripple current specifications at 120 Hz (45 mA) and 10 kHz (90 mA) allow designers to assess behavior across audio-relevant frequencies.
• Measured electrical characteristics: Specified tan δ and leakage current values provide deterministic parameters for circuit simulation and margining.
• Supply options for assembly: Available in bulk (no terminal forming) or bag packing to match production and prototyping workflows.

Why Choose UKA0J220MDD?

The UKA0J220MDD positions itself as a compact, audio-focused aluminum electrolytic capacitor with clear, measured electrical specifications that design and procurement teams can use directly in BOMs and simulations. Its combination of 22 µF capacitance, 6.3 V rating, defined tan δ, low leakage current, and ripple current data supports designers targeting stable audio performance across temperature.

This part is appropriate for engineers and manufacturers of audio equipment who require documented behavior (including endurance at 105 °C) and straightforward, through-hole form factor options for assembly. The AEC-Q200 designation noted in the series specifications can help meet qualification expectations where that standard is required.
