ULD2W8R2MPD

The ULD2W8R2MPD is an aluminum electrolytic capacitor in a radial-lead can designed for high-voltage, long-life applications. It is part of Nichicon's ULD series and provides a compact 8.2 µF capacitance at a 450 V rating with polarized radial leads.

Engineered for applications that require extended endurance at elevated temperatures, this part delivers 20,000 hours of rated life at 105°C and is suited for general-purpose high-voltage power supply use, including LED lighting power supplies.

Key Features

• Electrical Rating — 8.2 µF capacitance with a 450 V rated voltage and tolerance of -20% to +20%.
• Long Life Endurance — Rated for 20,000 hours at 105°C, providing extended service life in high-temperature environments.
• Temperature Range — Operating range from -40°C to +105°C, supporting a wide range of ambient conditions.
• Ripple Performance — Low-frequency ripple current 88 mA (120 Hz) and high-frequency ripple current 167.2 mA (100 kHz) for reliable filtering in diverse switching environments.
• Leakage and Loss — Specified leakage current 247.6 µA and tan δ of 0.24 (measured at 20°C, 120 Hz), enabling predictable loss and leakage characteristics.
• Compact Radial Package — φ10 × 20 mm can with 5 mm lead spacing (±0.5 mm tolerance) for through-hole mounting and straightforward PCB placement; available in bulk/bag packing.
• Regulatory — RoHS compliant, supporting restricted-substance requirements.

Typical Applications

• LED Lighting Power Supplies — Provides high-voltage smoothing and energy storage suitable for LED driver designs that require long operational life at elevated temperature.
• General-Purpose Power Filtering — Used for decoupling and bulk filtering in high-voltage power supply circuits where 450 V ratings are required.
• High-Voltage Electronics — Fits compact, through-hole assemblies needing a durable electrolytic with defined ripple and leakage specifications.

Unique Advantages
