UKA1C220MDD

The UKA1C220MDD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKA series, designed around high-grade audio applications. This polarized, can-style capacitor delivers 22 µF capacitance at a 16 V rating in a compact φ5 × 11 mm package with 2 mm lead spacing.

Engineered for extended temperature operation and endurance, the part offers a wide operating range (−55 °C to +105 °C), AEC-Q200 rating, low leakage and controlled dissipation factor—attributes useful in demanding audio circuits and other systems requiring stable decoupling and filtering over time and temperature.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with tolerance −20% to +20% and a rated voltage of 16 V.
• Temperature Range & Endurance — Rated for operation from −55 °C to +105 °C with a lifetime (endurance) of 2000 hours at 105 °C.
• Dissipation Factor (tan δ) — tan δ = 0.22 measured at 20 °C, 120 Hz, providing predictable loss characteristics for audio-grade applications.
• Leakage & Ripple Performance — Low leakage current (10.56 µA) with rated ripple currents of 54 mA at 120 Hz (low frequency) and 108 mA at 10 kHz (high frequency).
• Package & Mounting — Radial lead, can-style package (φ5 × 11 mm) with 2.0 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing.
• Qualification — AEC-Q200 rated, indicating compliance with the qualification standard listed in the product data.

Typical Applications

• High-grade audio equipment — Suitable for audio systems where stable capacitance, low leakage and controlled dissipation are needed across a wide temperature range.
• Audio power-supply decoupling — Compact radial form factor for board-level smoothing and local energy storage in audio power rails.
• Audio signal-stage support — Use where polarized electrolytic capacitance is required for coupling, bypass or timing in audio circuits.

Unique Advantages

• Wide operating temperature — −55 °C to +105 °C operation supports designs exposed to broad environmental ranges.
• Long endurance at elevated temperature — 2000 hours at 105 °C provides predictable life performance for long-term deployments.
• Low leakage current — 10.56 µA leakage supports low-noise and low-bias drift requirements in sensitive audio circuits.
• Measured loss characteristics — tan δ of 0.22 at 16 V, 120 Hz gives designers a defined dissipation baseline for audio performance tuning.
• Compact radial can — φ5 × 11 mm size and 2 mm lead spacing enable dense board placement in small audio modules and assemblies.
• AEC-Q200 qualification — Conformance to the listed qualification standard supports use in designs requiring that level of component qualification.
