ULD2C330MPD

The ULD2C330MPD from Nichicon is a miniature-sized aluminum electrolytic capacitor in the ULD series designed for long life in compact power designs. It is a polarized, radial-lead can rated at 33 µF and 160 V, intended for general-purpose power filtering with specific suitability for power supplies in LED lighting.

Key value propositions include a long rated life of 20000 hours at +105°C, compact radial packaging, and documented ripple current capability across low and high frequencies—making it a practical choice for space-constrained, high-reliability power applications.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a rated voltage of 160 V and ±20% tolerance at 120 Hz, 20°C.
• Long Life Endurance — Engineered for 20000 hours of load life at +105°C, supporting sustained operation under elevated temperature and bias conditions.
• Temperature Range — Operational from −40°C to +105°C, suitable for applications with wide ambient variation.
• Radial Through‑Hole Package — Radial can with radial lead mounting, 5 mm lead spacing and compact dimensions (L: 1.6 × D: 1.0 cm) for easy PCB assembly and mechanical stability.
• Ripple Current Capability — Specified ripple current of 158 mA at 120 Hz and 284.4 mA at 100 kHz, enabling ripple handling across low and high frequency domains.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), meeting common environmental directive requirements.

Typical Applications

• LED Lighting Power Supplies — Designed and recommended for power supply use in LED lighting, providing smoothing and energy buffering for driver circuits.
• General Purpose Power Filtering — Suited for general-purpose DC filtering and decoupling in compact power assemblies.
• Compact/Space-Constrained Designs — Miniature form factor and radial can package enable use where board space is limited and through-hole mounting is preferred.

Unique Advantages

• Extended operational life: 20000 hours at +105°C offers longer maintenance intervals and predictable end-of-life planning for deployed systems.
• High-voltage rating: 160 V allows use in higher-voltage rails compared with lower-voltage electrolytic options, expanding design flexibility.
• Compact footprint: Small can dimensions (L: 1.6 × D: 1.0 cm) reduce board area while retaining through-hole robustness.
• Broad temperature capability: −40°C to +105°C operation supports a wide range of environmental conditions without derating the capacitor’s baseline specifications.
• Documented ripple performance: Specified ripple currents at 120 Hz and 100 kHz let designers size components with confidence for both mains‑frequency and high‑frequency converter applications.
• Regulatory readiness: RoHS compliance supports environmentally regulated product assemblies.
