UHD1C471MPD6

The UHD1C471MPD6 is a radial-lead aluminum electrolytic capacitor offering 470 µF capacitance at a 16 V rating in a compact φ10 × 12.5 mm can. It is part of Nichicon’s UHD series designed for high-ripple, low-impedance applications and general-purpose electronic designs.

With a −40°C to 105°C operating range and 4,000 hour endurance at 105°C, this capacitor targets designs that require reliable smoothing and decoupling under continuous bias and ripple conditions while maintaining a small footprint and standard radial mounting.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with tolerance −20% to +20% and a rated voltage of 16 V.
• Radial Lead Package — φ10 × 12.5 mm can with radial leads, 5.0 mm lead spacing (±0.5 mm), suitable for through-hole assemblies and bulk or bag packing.
• High Ripple / Low Impedance — Designed for high ripple environments with specified ripple current of 772.5 mA at 120 Hz and 1.03 A at 100 kHz, and a low loss tangent (tanδ) of 0.16 at 20°C, 120 Hz.
• Wide Temperature & Endurance — Rated for −40°C to +105°C operation and an endurance rating of 4,000 hours at 105°C (φ10 case), supporting continuous biased operation at elevated temperature.
• Leakage Current & Stability — Specified leakage current of 75.2 µA (measured after rated voltage application), with capacitance and dissipation specifications maintained after endurance testing per the UHD series data.
• Regulatory & Packaging — RoHS-compliant construction with mass-production availability and packaging options in bulk (no terminal forming) or bag packing.

Typical Applications

• Power Filtering and Smoothing: Use on DC power rails to reduce ripple and stabilize supply voltages thanks to the UHD1C471MPD6’s high ripple-current capability and low impedance.
• Switching Power Supplies: Suitable for decoupling and bulk capacitance at switching frequencies, supported by the specified ripple current at 100 kHz.
• Embedded & Industrial Electronics: Reliable operation across −40°C to 105°C and 4,000-hour endurance at elevated temperature make it appropriate for long-running embedded and industrial control boards.
• General-Purpose Consumer Electronics: Compact φ10 can and radial-lead form factor provide an easy-to-mount option for space-conscious PCB layouts in consumer devices.

Unique Advantages

• High ripple handling capability: Explicit ripple current ratings at both low and high frequencies allow designers to size capacitors confidently for ripple-intensive circuits.
• Low loss at operating frequency: A tanδ of 0.16 (20°C, 120 Hz) supports lower dissipation and predictable thermal behavior under AC stress.
• Compact radial can: φ10 × 12.5 mm case minimizes board area while preserving capacitance, simplifying layout for through-hole designs.
• Wide operating temperature and proven endurance: −40°C to 105°C rating with 4,000 hours endurance at 105°C provides predictable life performance in continuous-duty applications.
• Controlled leakage characteristics: Specified leakage current enables accurate power budgeting and standby current estimates for system design.
• RoHS-compliant production and packaging options: Environmentally compliant construction with bulk or bag packing to suit production and prototyping workflows.
