UKA1H470MED

The UKA1H470MED is an aluminum electrolytic capacitor from Nichicon's UKA series engineered for high-grade audio equipment. It is a polarized, radial-leaded can designed to provide bulk energy storage, smoothing and decoupling in audio power circuits.

Key value comes from its wide operating temperature range (−55°C to +105°C), a 50 V rating with 470 µF capacitance, and durability characteristics specified for long-term operation in demanding environments.

Key Features

• Capacitance and Tolerance — 470 µF with ±20% tolerance measured at 120 Hz, 20°C, providing predictable bulk capacitance for audio power rails.
• Voltage Rating — Rated at 50 V to support higher-voltage audio supply rails and headroom in amplifier designs.
• Wide Temperature Range — Specified from −55°C to +105°C to maintain performance across extreme ambient conditions.
• Endurance — Qualified for 2000 hours at 105°C with defined limits on capacitance change, tan δ and leakage current after endurance testing.
• Ripple Current Capability — Rated ripple current: 115 mA at 120 Hz and 230 mA at 10 kHz, suitable for typical audio ripple and transient conditions.
• Leakage Current Specification — Leakage current limits per datasheet: after 1 minute at 20°C no more than 0.03CV (µA); after 2 minutes no more than 0.01CV (µA), where C is µF and V is rated voltage.
• Low Loss Angle (tan δ) — Series tan δ limits include a maximum of 0.14 at 50 V (measured at 120 Hz, 20°C), supporting low dissipation in audio circuits.
• Package and Mounting — Radial lead, can-type package with 2.5 mm lead spacing and compact dimensions (L: 1.1 × D: 0.63 cm) for through-hole assembly.
• Marking and Compliance — Printed with black lettering on a pearl blue sleeve; RoHS compliant; rated AEC-Q200.

Typical Applications

• High‑grade Audio Amplifiers — Bulk smoothing and power‑rail decoupling to support clean, stable power delivery in amplifier stages.
• Preamp and DAC Power Supplies — Local energy storage to reduce supply ripple and support transient response in sensitive audio front ends.
• Audio Power Modules — Filtering and transient handling in power supply modules for consumer and professional audio equipment.

Unique Advantages

• Designed for audio use: Application designation and construction target high‑grade audio equipment, aligning electrical characteristics with audio power needs.
• Wide operating temperature: −55°C to +105°C rating enables reliable operation in a broad range of installation environments and thermal conditions.
• Long endurance at elevated temperature: 2000‑hour specification at 105°C provides predictable long‑term behavior for sustained deployments.
• Measured ripple performance: Specified ripple currents at 120 Hz and 10 kHz address both mains‑frequency smoothing and higher‑frequency switching or transient components.
• Automotive‑grade reliability marker: AEC‑Q200 rating signals series‑level reliability processes where applicable.
• Compact radial can package: Through‑hole form factor with clear sleeve marking simplifies assembly and identification on the production line.
