ULD2A100MED

The ULD2A100MED from Nichicon is a miniature, radial-lead aluminum electrolytic capacitor designed for long-life power applications. It delivers 10 µF capacitance at a 100 V rating in a compact radial can package suited to through-hole mounting and space-constrained boards.

Engineered for durability, this part withstands a 10 000‑hour load life at +105 °C and is specifically noted for use in power supplies for LED lighting. The capacitor is polarized, RoHS compliant, and intended for general-purpose power filtering and energy storage in electronic systems.

Key Features

• Capacitance & Voltage — 10 µF nominal capacitance with a 100 V rated voltage, suitable for higher-voltage rail filtering and energy storage needs.
• Long Life Assurance — Rated for 10 000 hours at +105 °C under D.C. bias plus rated ripple current (per series endurance specification for 10–100 V parts), supporting extended service life in demanding thermal environments.
• Temperature Range — Operates from −40 °C to +105 °C, enabling deployment across a wide range of ambient conditions.
• Ripple Current Capability — Specified ripple current handling of 63 mA at 100 Hz and 150 mA at 100 kHz, useful for smoothing and decoupling in switching supplies and LED drivers.
• Compact Radial Can Package — Radial lead, through-hole mounting with a small footprint (L: 1.1 cm × D: 0.63 cm) and 2.5 mm lead spacing for compact board layouts.
• Polarized Design & Tolerance — Polarized electrolytic capacitor with ±20% capacitance tolerance at 120 Hz, 20 °C.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), meeting common environmental requirements for electronic components.

Typical Applications

• LED Lighting Power Supplies — Used for bulk filtering and energy smoothing in LED driver circuits where long life at elevated temperature is required.
• Switching Power Supplies — Provides decoupling and ripple attenuation on higher-voltage rails in compact, through-hole power supply designs.
• General-Purpose Power Filtering — Suitable for general-purpose smoothing, bypassing, and energy storage in industrial and consumer electronics.

Unique Advantages

• Extended High‑Temperature Endurance: The 10 000‑hour rating at +105 °C offers designers predictable performance over long operational periods in thermally stressful power systems.
• Compact Footprint for Through‑Hole Designs: Small radial can dimensions and tight lead spacing enable space-efficient layouts without sacrificing voltage capability.
• High Voltage Capability: 100 V rating supports higher-voltage rails and applications where extra voltage margin is required.
• Measured Ripple Performance: Specified ripple current values at both low and high frequency provide clear guidance for thermal and lifetime budgeting in power designs.
• Regulatory Compliance: RoHS conformity simplifies selection for designs targeting regulated markets and helps ensure environmental compliance.
