UKT1C471MPD

The UKT1C471MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKT series, engineered for general audio equipment. It combines a compact radial can package with specifications tuned for audio power filtering and decoupling in wide temperature environments.

Key value propositions include a 470 µF capacitance at 16 V, AEC-Q200 qualification, a wide operating temperature range of −55°C to 105°C, and specified ripple current capability across low and high frequencies.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance with a rated voltage of 16 V and a tolerance of −20% to +20%.
• Low-loss Performance — tanδ (DF) 0.22 measured at 20°C, 120 Hz for the 16 V rating, supporting stable audio performance.
• Ripple Current Handling — Low-frequency ripple current 315 mA at 120 Hz and high-frequency ripple current 472.5 mA at 10 kHz, enabling effective smoothing of power rails in audio circuits.
• Leakage Current — Specified leakage current of 225.6 µA, meeting typical electrolytic leakage expectations for the rated capacitance and voltage.
• Robust Temperature & Endurance — Operating temperature range from −55°C to 105°C with endurance of 1000 hours at 105°C.
• Radial Can Package — Compact φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm), ideal for through-hole radial mounting and repair/replacement applications.
• Qualification & Compliance — AEC-Q200 qualification and RoHS directive compliance as specified for the UKT series.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible procurement and assembly workflows.

Typical Applications

• Audio Equipment — Power supply decoupling and smoothing in general audio devices, where stable capacitance and low-loss behavior at 105°C are required.
• Through-hole Board Designs — Radial-lead mounting for board-level power filtering in consumer and professional audio assemblies.
• High-Temperature Environments — Circuits exposed to elevated ambient temperatures up to 105°C that require sustained performance over 1000 hours.

Unique Advantages

• Wide Temperature Capability: −55°C to 105°C operating range supports designs exposed to extreme temperature variations.
• High Ripple Current Capacity: Defined ripple current specs at both 120 Hz and 10 kHz (315 mA and 472.5 mA) provide predictable performance across audio and switching-frequency environments.
• Proven Endurance: 1000 hours rated life at 105°C allows designers to specify long-term stability for challenging thermal conditions.
• Compact Radial Form Factor: φ8 × 11.5 mm can with 3.5 mm lead spacing offers a small footprint for dense through-hole layouts and retrofit applications.
• Qualification & Compliance: AEC-Q200 qualification and RoHS directive compliance (per UKT series datasheet) support regulated design requirements.
• Mass Production Availability: Listed as mass production, supporting consistent supply for manufacturing quantities.
