ULD2W6R8MPD

The ULD2W6R8MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's ULD series, engineered for long-life high-voltage applications. It provides 6.8 µF capacitance at a 450 V rating in a compact φ10 × 16 mm can, making it suitable for high-voltage DC filtering and general-purpose power supply use, including LED lighting power supplies.

Key value propositions include a 20000-hour endurance at 105°C, measurable loss characteristics (tanδ), and specified ripple and leakage performance to support reliable operation in sustained, high-voltage environments.

Key Features

• Capacitance & Tolerance — 6.8 µF nominal capacitance with tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• High Voltage Rating — Rated for 450 V to support high-voltage DC filtering and power conversion stages.
• Long Life Endurance — Load-life rated for 20000 hours at +105°C, suitable for designs requiring extended operational lifetime.
• Loss Tangent (tanδ) — Specified tanδ of 0.24 (measured at 20°C, 120 Hz) for predictable dissipation behavior in AC conditions.
• Ripple Current Specified — Low-frequency ripple current of 62 mA at 120 Hz and high-frequency ripple current of 117.8 mA at 100 kHz, enabling performance characterization across frequencies.
• Leakage Current — Measured leakage current of 222.4 µA for evaluation of standby losses and insulation performance.
• Compact Radial Package — φ10 × 16 mm can with 5.0 mm lead spacing (±0.5 mm) and radial lead mounting for straightforward through-hole PCB implementation.
• Environmental Compliance — RoHS compliant.
• Packaging & Availability — Available in bulk (no terminal forming) or bag packing; part is in mass production.

Typical Applications

• LED Lighting Power Supplies — Provides high-voltage capacitance and long-life endurance for DC filtering and smoothing in LED driver circuits.
• High-Voltage DC Filtering — 450 V rating and defined ripple/current specs support use in high-voltage bus decoupling and filtering.
• General-Purpose Power Supplies — Suitable for general-purpose power conditioning where a compact radial electrolytic capacitor with long operational life is required.

Unique Advantages

• Extended Operational Life: 20000 hours at 105°C reduces maintenance and replacement needs in continuous-duty applications.
• High-Voltage Capability: 450 V rating enables use in high-voltage power stages and DC link circuits.
• Frequency-Aware Ripple Data: Specified ripple currents at 120 Hz and 100 kHz allow designers to assess performance across both low- and high-frequency conditions.
• Compact Radial Form Factor: φ10 × 16 mm can and 5 mm lead spacing support space-conscious through-hole designs.
• Quantified Dielectric Loss: tanδ value at 120 Hz provides a measurable parameter for thermal and dissipation planning.
• Regulatory Compliance: RoHS status supports environmentally regulated product builds.
