UKL1A471MPD

The UKL1A471MPD is a radial-lead aluminum electrolytic capacitor in Nichicon's UKL low-leakage series. It provides 470 µF capacitance at 10 V with a compact φ10 × 16 mm can and 5 mm lead spacing, tailored for applications that value low leakage and reliable ripple-handling.

Commonly applied in audio electronics, this component combines low leakage characteristics with specified ripple current capability and a rated endurance of 2000 hours at 85°C, making it a practical choice for through-hole designs requiring stable performance in the −40°C to 85°C operating range.

Key Features

• Electrical Performance — 470 µF capacitance with ±20% tolerance at 10 V rated voltage; leakage current specified at 9.4 µA.
• Ripple Current Handling — Low-frequency ripple current of 530 mA at 120 Hz and high-frequency ripple current of 795 mA at 10 kHz for effective AC load handling.
• Low Loss (tan δ) — Dissipation factor (tan δ) appropriate to the φ10 × 16 case and 10 V rating (0.17), supporting stable AC performance.
• Reliability & Endurance — Rated lifetime of 2000 hours at 85°C with operating temperature range of −40°C to 85°C.
• Package & Mounting — Radial-lead can, case size φ10 × 16 mm, lead spacing 5 mm (±0.5 mm) and lead diameter 0.6 mm for straightforward through-hole mounting.
• Packaging Options — Supplied in Bulk (No Terminal Forming) or Bag Packing to suit assembly and inventory preferences.
• RoHS Compliant — Manufactured to meet RoHS requirements.

Typical Applications

• Consumer Audio Equipment — Used in audio circuits where low leakage and defined ripple capability support stable biasing and power decoupling.
• Professional Audio Gear — Suitable for through-hole audio designs that require reliable ripple handling and endurance at elevated temperatures.
• Audio Power Supplies — Functions as a reservoir/filtration element in power sections of audio devices, leveraging its 470 µF capacitance and ripple-current ratings.

Unique Advantages

• Low Leakage Characteristics — Part of Nichicon's standard low-leakage UKL series, reducing standby losses and bias drift in sensitive circuits.
• Balanced Ripple Capability — Explicit low- and high-frequency ripple current ratings (530 mA at 120 Hz, 795 mA at 10 kHz) provide measurable performance across typical audio frequencies.
• Compact Through-Hole Form — φ10 × 16 mm radial can with 5 mm lead spacing offers a small footprint for tight PCB layouts.
• Temperature and Endurance Ratings — −40°C to 85°C operating range and 2000 h endurance at 85°C support sustained use in heat-stressed enclosures.
• Supply Flexibility — Available in bulk or bag packing to accommodate prototyping and production needs.
