ULD2E120MPD

The ULD2E120MPD is an aluminum electrolytic capacitor in a radial lead can designed for general-purpose applications. It pairs a compact φ10×12.5 mm package with a 250 V rated voltage and 12 µF capacitance for use in board-mounted power circuits.

Designed as part of Nichicon’s ULD long-life family, this part supports extended endurance at elevated temperature and is suited for power-supply use cases such as LED lighting power supplies and other general-purpose power applications.

Key Features

• Capacitance & Voltage — 12 µF nominal capacitance with a rated voltage of 250 V and capacitance tolerance of −20% to +20%.
• Long-life Endurance — Rated for 15,000 hours at 105°C (specific to the φ10×12.5L size), providing extended operational life under elevated-temperature bias.
• Temperature Range — Operating temperature from −40°C to +105°C to support a wide range of environmental conditions.
• Radial Lead Package — Radial, can-style package with φ10×12.5 mm dimensions and 5.0 mm lead spacing (±0.5 mm tolerance) for through-hole PCB mounting.
• Electrical Loss and Leakage — Tan δ (DF) of 0.24 measured at 20°C, 120 Hz, and specified leakage current of 220 µA.
• Ripple Current Ratings — Low-frequency ripple current 97 mA at 120 Hz and high-frequency ripple current 184.3 mA at 100 kHz, suitable for smoothing and ripple management in power circuits.
• Packaging Options — Available in bulk (no terminal forming) and bag packing for flexible procurement and assembly handling.
• Regulatory — RoHS-compliant.

Typical Applications

• LED Lighting Power Supplies — Suited for use in power-supply stages for LED lighting where long life at elevated temperature is required.
• General-Purpose Power Electronics — Applicable to general-purpose smoothing and decoupling in board-level power circuits that require a 250 V rated capacitor.
• Compact Through-Hole Designs — Radial lead, φ10×12.5 mm package with 5 mm lead spacing for space-conscious through-hole PCB layouts.

Unique Advantages

• Extended High‑Temperature Life: 15,000 hours at 105°C for the φ10×12.5L size supports longer service life in thermally demanding power applications.
• High Voltage Capability: 250 V rating enables use in higher-voltage rails and power-supply sections without up-rating components.
• Verified AC Performance: Specified tan δ (0.24 at 20°C, 120 Hz) lets designers account for dielectric loss in filter and timing applications.
• Defined Ripple Handling: Published ripple current values at 120 Hz and 100 kHz (97 mA and 184.3 mA) allow accurate thermal and lifetime budgeting for ripple-bearing circuits.
• Compact Radial Form Factor: φ10×12.5 mm can and 5 mm lead spacing deliver a small footprint for through‑hole board layouts while maintaining rated performance.
• RoHS Compliance: Meets RoHS requirements for use in regulated assemblies.
