ULD1C470MDD

The ULD1C470MDD is a radial-lead aluminum electrolytic capacitor from Nichicon's ULD series, offered in a miniature φ5×11 mm can. It provides 47 µF capacitance at a 16 V rating with a design focus on long-life performance for board-level power filtering and smoothing.

Sized for compact assemblies and suited for general-purpose power applications, the part combines long endurance at elevated temperature with controlled dissipation and low leakage for reliable operation in sustained duty circuits.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance rated at 16 V with a tolerance of -20% to +20% (measured at 20°C, 120 Hz).
• Long Life Endurance — Specified for 10,000 hours at 105°C under rated conditions per the ULD series endurance characteristics.
• Low Leakage — Measured leakage current specified at 7.52 µA after voltage application, supporting minimized off-state drain.
• Dissipation Factor (tan δ) — tan δ (DF) 0.35 measured at 20°C, 120 Hz for 16 V parts, enabling predictable AC loss behavior.
• Ripple Handling — Low-frequency ripple current 91 mA at 120 Hz and high-frequency ripple current 130 mA at 100 kHz for use in ripple-susceptible circuits.
• Compact Radial Package — φ5×11 mm can with 2.0 mm lead spacing (±0.5 mm tolerance) in a radial-lead form factor for through-hole mounting and easy assembly.
• Wide Operating Temperature — Rated for operation from -40°C to +105°C to cover a broad range of environmental conditions.
• RoHS Compliant — Conforms to RoHS requirements as noted for the ULD series.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for assembly flexibility.

Typical Applications

• LED Lighting Power Supplies — Suited for power supply smoothing and filtering in LED driver circuits where long-life operation at elevated temperature is required.
• General-Purpose Power Filtering — Board-level decoupling and smoothing in compact through-hole designs across consumer and industrial electronics.
• Compact Radial Assemblies — Use in space-constrained modules that require a miniature aluminum electrolytic with defined ripple and leakage characteristics.

Unique Advantages

• Long operational life: 10,000 hours at 105°C under rated conditions delivers predictable endurance for sustained-duty circuits.
• Compact form factor: φ5×11 mm can and 2.0 mm lead spacing enable tight board placement in through-hole designs.
• Measured low leakage: 7.52 µA leakage current reduces parasitic drain and supports stable bias conditions.
• Defined dissipation: tan δ of 0.35 at 120 Hz (20°C) provides a clear loss metric for thermal and efficiency planning.
• Ripple capability across frequencies: Specified ripple currents at both 120 Hz and 100 kHz help assess performance under common power conversion conditions.
• RoHS compliant: Meets RoHS requirements for regulatory conformity in assemblies.
