ULD2G2R2MPD

The ULD2G2R2MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s ULD series, designed for long-life operation in compact power circuits. It combines a 2.2 μF capacitance with a 400 V rated voltage and a miniature φ8 × 11.5 mm can size, making it suitable for high-voltage filtering and smoothing in general-purpose power applications, including LED lighting power supplies.

Built for durability, this part is specified for 15,000 hours at 105°C and is RoHS compliant, offering predictable electrical performance over extended field life.

Key Features

• Capacitance & Voltage — 2.2 μF capacitance rated at 400 V for high-voltage filtering and energy storage in compact assemblies.
• Long-Life Endurance — Rated for 15,000 hours at 105°C, providing extended service life in elevated-temperature environments.
• Low Loss Characteristics — tanδ = 0.24 measured at 20°C, 120 Hz, enabling controlled dissipation for stable performance.
• Leakage Current — Specified leakage current of 128 μA for predictable standby and idle behavior.
• Ripple Current Capability — Low-frequency ripple current 40 mA (120 Hz) and high-frequency ripple current 80 mA (100 kHz) for AC ripple handling across frequencies.
• Compact Radial Package — φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole designs with tight board real estate.
• Polarized, General-Purpose Use — Polarized aluminum electrolytic optimized for general-purpose power applications.
• Packaging & Availability — Available in bulk (no terminal forming) or bag packing; status: mass production.

Typical Applications

• LED lighting power supplies — Provides high-voltage smoothing and long operational life for driver circuits used in LED luminaires.
• High-voltage power filtering — Suitable for filtering and decoupling in 400 V class power assemblies and general-purpose power electronics.
• General-purpose electronic equipment — Use where a compact, long-life polarized capacitor is required for energy storage and ripple suppression.

Unique Advantages

• Extended thermal endurance: 15,000-hour rating at 105°C reduces replacement cycles and supports designs exposed to elevated operating temperatures.
• High-voltage capability: 400 V rating allows direct use in higher-voltage rails without additional series components.
• Small footprint: φ8 × 11.5 mm can and 3.5 mm lead spacing enable compact through-hole layouts and high-density board designs.
• Predictable electrical behavior: Specified tanδ and measured leakage current give designers clear parameters for thermal and standby budgeting.
• Frequency-flexible ripple handling: Defined ripple current at both low (120 Hz) and high (100 kHz) frequencies supports performance across switching regimes.
• Regulatory compliance: RoHS compliant for use in regulated markets and assemblies.
