UKA1A470MDD

The UKA1A470MDD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKA series, specified at 47 µF with a 10 V rating. It is designed for audio and electronics applications that require a compact polarized electrolytic with a wide operating temperature range and defined ripple/leakage performance.

The component combines a small φ5 × 11 mm can with 2 mm lead spacing and is engineered for long-term operation up to 105°C with a 2000-hour endurance rating, making it suitable where stable capacitance, controlled leakage and frequency-dependent ripple performance are required.

Key Features

• Capacitance & Tolerance — 47 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C, providing predictable charge storage for circuit design.
• Rated Voltage & Polarization — 10 V rated voltage; polarized electrolytic construction for DC power and signal applications.
• Thermal Range & Endurance — Operating temperature range −55°C to +105°C with an endurance specification of 2000 hours at 105°C.
• Ripple Current Performance — Specified low-frequency ripple current of 68 mA (120 Hz) and high-frequency ripple current of 136 mA (10 kHz), suitable for filtering and decoupling in frequency-varying environments.
• Low Leakage Current — Leakage current specified at 14.1 µA, supporting low-noise and low-bias applications where minimal DC leakage is important.
• Package & Mounting — Radial lead can package (φ5 × 11 mm) with 2 mm lead spacing for through-hole mounting and straightforward PCB placement.
• Industry Qualification — Part of the UKA series with AEC‑Q200 noted in the product specifications, indicating qualification for demanding reliability environments.

Typical Applications

• High-grade Audio Equipment — Targeted for audio systems where stable capacitance, low leakage and controlled ripple behavior contribute to signal fidelity and power supply smoothing.
• Automotive Electronics — AEC‑Q200 listing supports use in automotive designs that require components capable of withstanding extended thermal and electrical stress.
• Temperature-challenged Electronics — With a −55°C to +105°C operating range and 2000-hour endurance at 105°C, suitable for embedded and industrial applications operating across wide temperature spans.

Unique Advantages

• Compact radial package: φ5 × 11 mm can and 2 mm lead spacing provide a small footprint for space-constrained boards while maintaining through-hole reliability.
