ULD2D270MPD

The ULD2D270MPD is a radial lead aluminum electrolytic capacitor from Nichicon’s ULD series, designed for long-life, miniature power applications. It provides 27 µF capacitance at a 200 V rated voltage in a compact φ10×16L can with 5 mm lead spacing.

Engineered for general-purpose power supply use, including LED lighting power supplies, this capacitor combines extended endurance with stable electrical characteristics across a wide temperature range for reliable smoothing, filtering, and decoupling in compact assemblies.

Key Features

• Capacitance and Tolerance — 27 µF nominal capacitance with a tolerance of -20% to +20% at 120 Hz, 20 °C.
• Rated Voltage — 200 V working voltage suitable for medium-voltage power rails.
• Long Life Endurance — Rated for 20000 hours at 105 °C per ULD series specifications, providing extended service life under elevated temperature and bias.
• Temperature Range — Operates from -40 °C to +105 °C to support a broad range of environmental conditions.
• Low and High Frequency Ripple Handling — Low-frequency ripple current 149 mA (120 Hz) and high-frequency ripple current 268.2 mA (100 kHz) for effective smoothing across frequencies.
• Loss and Leakage — Tangent of loss angle (tanδ) of 0.24 (measured at 20 °C, 120 Hz) and leakage current of 316 µA for predictable dissipation and low standby loss.
• Form Factor — Radial lead, polarized can with size φ10×16L (D: 1.0 cm × L: 1.6 cm) and 5 mm lead spacing (±0.5 mm) for through-hole PCB layouts.
• Packaging and Compliance — Available in bulk (no terminal forming) or bag packing; RoHS compliant and in mass production.

Typical Applications

• LED Lighting Power Supplies — Smoothing and energy storage in LED drivers where long life at elevated temperature is required.
• General-Purpose Power Filtering — Bulk decoupling and ripple suppression on medium-voltage rails in compact power modules.
• Consumer and Industrial Electronics — Through-hole radial mounting for board-level smoothing and transient absorption in a variety of equipment.

Unique Advantages

• Extended High-Temperature Endurance: 20000 hours at 105 °C supports designs that must maintain capacitance and leakage stability over long operational lifetimes.
• Compact Miniature Footprint: φ10×16L can and 5 mm lead spacing allow dense through-hole layouts without sacrificing capacitance or voltage rating.
• Dual-Frequency Ripple Capability: Specified ripple current values at 120 Hz and 100 kHz enable effective filtering across both low- and high-frequency components.
• Measured Dissipation and Leakage: tanδ of 0.24 and leakage current of 316 µA give engineers quantifiable parameters for thermal and standby power budgeting.
• Polarized Radial Configuration: Radial lead, polarized package simplifies through-hole assembly for established PCB processes and mechanical mounting.
• Regulatory Compliance and Availability: RoHS compliant and currently in mass production for reliable supply chain planning.
