UKA1C471MPD

The UKA1C471MPD is a polarized aluminum electrolytic capacitor in a radial can package, engineered for high‑grade audio equipment. It provides 470 µF at a 16 V rating with a wide operating temperature range of −55°C to +105°C and a rated lifetime of 2000 hours at 105°C.

Designed for applications that demand stable capacitance, controlled loss (tan δ), and robust ripple handling, this part balances compact size (φ8×11.5 mm) with measurable leakage and ripple specifications suitable for audio-focused designs.

Key Features

• Capacitance and Voltage — 470 µF rated capacitance at 16 V with a tolerance of ±20% (measured at 120 Hz, 20°C).
• Temperature Range & Endurance — Operates from −55°C to +105°C and meets endurance requirements after 2000 hours at 105°C.
• Low‑frequency loss (tan δ) — Tangent of loss angle (tan δ) of 0.22 at 120 Hz and 20°C, supporting predictable AC performance in audio circuits.
• Leakage Current — Specified maximum leakage of 225.6 µA after 1 minute and 75.2 µA after 2 minutes at 20°C (based on 0.03CV and 0.01CV limits).
• Ripple Current Capability — Rated ripple current of 315 mArms at 105°C/120 Hz, with higher-frequency capability listed at 472.5 mA at 10 kHz for relevant use cases.
• Package & Mounting — Radial lead (can) package, case size φ8×11.5 mm, lead spacing 3.5 mm (±0.5 mm), supplied in bulk with no terminal forming.
• Reliability Rating — Manufactured to a component rating of AEC‑Q200 for enhanced reliability in demanding environments.

Typical Applications

• High‑Grade Audio Equipment — Suited for audio designs where stable bulk capacitance and controlled loss across a wide temperature range are required.
• Power Supply Filtering — Use where 16 V, 470 µF capacitance and defined ripple handling help smooth and stabilize local rails in audio systems.
• General Purpose Radial Mounting — Compact φ8×11.5 mm radial can for through‑hole PCB assemblies requiring polarized electrolytic capacitance.

Unique Advantages

• Wide operating temperature window — −55°C to +105°C supports stable performance in both cold and hot operating environments.
• Quantified leakage characteristics — Clear leakage current limits (225.6 µA / 75.2 µA) enable predictable bias and standby current budgeting.
• Measurable loss and ripple specs — tan δ = 0.22 and 315 mArms ripple rating at 120 Hz/105°C provide design‑level data for audio power stages.
• Compact radial can footprint — φ8×11.5 mm case and 3.5 mm lead spacing simplify placement in constrained PCB layouts.
• AEC‑Q200 rating — Component‑level reliability designation for applications that demand higher assurance under stress conditions.
