ULD2D180MPD

The ULD2D180MPD is a miniature aluminum electrolytic capacitor from Nichicon's ULD series, designed for long-life performance in compact radial-lead packages. It delivers 18 µF of capacitance at a 200 V rating in a small can-style, through-hole format.

Targeted for general-purpose power circuits, the part is explicitly suited for power supplies for LED lighting and other designs that require a compact, high-voltage electrolytic with extended operational life at elevated temperature.

Key Features

• Capacitance & Voltage — 18 µF nominal capacitance rated at 200 V, with capacitance tolerance of ±20%.
• Long-Life Endurance — Designed to withstand a load life of 15000 hours at +105°C, delivering extended service life in high-temperature applications.
• Operating Temperature Range — Specified for operation from −40°C to +105°C to cover a wide range of environmental conditions.
• Ripple Current Capability — Rated ripple current of 113 mA at 120 Hz and 214.7 mA at 100 kHz to handle AC stress on power rails.
• Package & Mounting — Radial lead, can-style package for through-hole PCB mounting; lead spacing 5 mm and compact size (L: 1.25 × D: 1.00 cm).
• Polarized Construction — Polarized aluminum electrolytic type for DC power filtering and energy storage in power circuits.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• LED Lighting Power Supplies — Suited for smoothing and bulk energy storage in LED driver circuits where long life at elevated temperature is required.
• General-Purpose Power Circuits — Applicable for general-purpose DC filtering and decoupling in through-hole designs.
• Through-Hole PCB Designs — Radial-lead package fits standard through-hole assemblies and PCB placements with 5 mm lead spacing.

Unique Advantages

• Extended High‑Temperature Lifetime: 15000 hours at +105°C provides predictable endurance for designs exposed to sustained elevated operating temperatures.
• Compact Footprint: Small can dimensions (L: 1.25 × D: 1.00 cm) enable high-density PCB layouts without sacrificing voltage rating.
• High Voltage Handling: 200 V rating supports higher-voltage rails in power supply and LED driver topologies.
• Measurable Ripple Performance: Specified ripple currents at both low and high frequencies give clear guidance for thermal and AC stress design considerations.
• RoHS Compliance: Meets applicable RoHS directives for regulatory compliance in commercial and industrial products.
