UKA1E471MPD

The UKA1E471MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKA series, designed for high-grade audio equipment and applications that require stable capacitance across a wide temperature range. This 470 µF, 25 V polarized can delivers low loss (tanδ 0.18 at 20°C, 120 Hz), defined ripple-handling capability, and a 2000-hour endurance at 105°C.

Its compact φ10 × 12.5 mm can, 5 mm lead spacing and radial-lead package make it suitable for densely packed boards where reliable audio-grade filtering and energy storage are required.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance rated at 25 V with ±20% tolerance for bulk energy storage and filtering in polarized circuits.
• Low Loss — Tangent of loss angle (tanδ) of 0.18 at 20°C and 120 Hz, supporting lower dissipation in audio-frequency applications.
• Ripple Current Performance — Rated ripple current of 380 mA at 120 Hz (low frequency) and 570 mA at 10 kHz (high frequency) for effective ripple handling across common audio and power frequencies.
• Leakage Current — Specified leakage current of 352.5 µA, measured under standard conditions for predictable DC performance.
• Wide Temperature & Endurance — Operating temperature range −55°C to +105°C with a rated lifetime of 2000 hours at 105°C for long-term stability under thermal stress.
• Compact Radial Can — φ10 × 12.5 mm body with 5 mm lead spacing and radial-lead mounting for through‑hole assembly and straightforward board placement.
• AEC-Q200 Rating — Rated to AEC-Q200, indicating qualification for applications that require that standard.
• Packaging & Availability — Supplied in bulk/bag packing with no terminal forming; part is in mass production.

Typical Applications

• High‑Grade Audio Equipment — Designed for use in high-grade audio systems where low loss and stable capacitance support cleaner power rails and signal fidelity.
• Audio Power Filtering — Suitable for filtering and smoothing in audio power supplies thanks to its ripple current capability and endurance at elevated temperature.
• General Analog Circuits — Employed where polarized bulk capacitance and wide temperature operation are required for analog signal and power stability.

Unique Advantages

• Audio‑oriented electrical characteristics — Low tanδ at 120 Hz helps minimize dissipation in audio-frequency circuits.
• Robust ripple handling — Defined ripple current ratings at both low and high frequencies provide predictable thermal performance in power and audio applications.
• Wide temperature resilience — −55°C to +105°C operating range and 2000 h endurance at 105°C support reliable operation in demanding environments.
• Automotive‑grade qualification — AEC‑Q200 rating supports designs that require that qualification level.
• Compact radial form factor — Small φ10 × 12.5 mm can and 5 mm lead spacing enable dense board layouts without sacrificing capacitance.
• Production readiness — Part is in mass production and supplied in bulk/bag packing for production-scale procurement.
