ULD1C271MPD

The ULD1C271MPD is a miniature radial-lead aluminum electrolytic capacitor from Nichicon's ULD series, designed for long-life operation in compact power designs. It delivers 270 µF at a 16 V rating with polarized radial-can packaging and is suited for general-purpose power supply applications, including LED lighting power supplies.

Engineered for elevated-temperature endurance, this part is rated for operation from -40 °C to +105 °C and specified to withstand 10,000 hours at +105 °C. The ULD1C271MPD is RoHS compliant for regulatory compatibility.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance at 120 Hz, 20 °C, providing bulk energy storage for power rails and smoothing.
• Long-Life Endurance — Rated lifetime of 10,000 hours at +105 °C under D.C. bias plus rated ripple current, giving predictable longevity in high-temperature environments.
• Operating Temperature Range — Specified for -40 °C to +105 °C operation to cover a wide range of industrial and lighting temperature profiles.
• Ripple Current Capability — Rated ripple current of 231 mA at 120 Hz and 330 mA at 100 kHz, enabling effective ripple handling in both low- and high-frequency power circuits.
• Compact Radial Can Package — Radial lead mounting with 3.5 mm lead spacing and a compact footprint (L: 1.15 × D: 0.8 cm) for space-constrained PCB layouts.
• Polarized, Through-Hole Mounting — Polarized aluminum electrolytic suitable for through-hole radial lead implementation where robust mechanical retention is required.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863) for restricted substances.

Typical Applications

• LED Lighting Power Supplies — Bulk filtering and smoothing in LED driver power stages where long life at elevated temperature is required.
• General-Purpose Power Supply Circuits — Energy storage and ripple suppression for low-voltage power rails in compact designs.
• Board-Level Power Filtering — Through-hole radial mounting for robust placement in applications needing mechanical durability and serviceable components.

Unique Advantages

• Extended High-Temperature Life: Specified 10,000 hours at +105 °C to support designs exposed to sustained elevated temperatures.
• High Capacitance at Low Voltage: 270 µF at 16 V provides substantial charge storage for smoothing and hold-up in compact circuits.
• Compact Footprint: Small radial-can dimensions (L: 1.15 × D: 0.8 cm) and low-profile construction enable space savings on crowded PCBs.
• Broad Ripple Handling: Clear ripple current ratings at both 120 Hz and 100 kHz allow designers to evaluate performance across typical switching and line-frequency environments.
• Regulatory Compatibility: RoHS compliance supports global product deployment without restricted substance concerns.
• Through-Hole Durability: Radial lead and can construction provide secure mechanical mounting and ease of replacement or rework.
