ULD1H100MDD

The ULD1H100MDD is a Nichicon ULD-series radial lead aluminum electrolytic capacitor specified at 10 µF and 50 V. It combines a miniature can package (φ5 × 11 mm) and long-life endurance to serve general-purpose power-supply filtering and decoupling needs.

Engineered for operation from -40°C to +105°C with a rated life of 10,000 hours at 105°C, this polarized capacitor is suited for compact board-level power circuits, including LED power supplies and other general-purpose electronic equipment.

Key Features

• Capacitance & Voltage — 10 µF nominal capacitance at a rated voltage of 50 V for board-level power filtering and decoupling.
• Long Life Endurance — Designed for 10,000 hours of operation at 105°C under rated conditions, supporting sustained performance in elevated-temperature environments.
• Low Leakage — Leakage current specified at 5 µA, minimizing standby losses in power rails.
• Dissipation Factor (tan δ) — tanδ of 0.19 measured at 20°C, 120 Hz, indicating predictable AC loss behavior at line frequencies.
• Ripple Current Capability — Low-frequency ripple current of 37.8 mA (120 Hz) and high-frequency capability of 90 mA (100 kHz) for smoothing and ripple attenuation across frequencies.
• Compact Radial Lead Package — φ5 × 11 mm can with 2.0 mm lead spacing (±0.5 mm) for tight-layout, through-hole assemblies; available in bulk or bag packing.
• Wide Temperature Range — Rated for -40°C to +105°C to handle a broad range of operating environments.
• RoHS Compliant — Conforms to RoHS requirements for lead-free assemblies.

Typical Applications

• LED Power Supplies — Provides filtering and ripple suppression in compact LED driver circuits where long life at elevated temperatures is required.
• General Purpose Power Filtering — Suited for bulk decoupling, smoothing and local energy storage on analog and digital power rails.
• Embedded and Industrial Electronics — Compact radial form factor and wide temperature rating make it appropriate for board-level power circuits in space-constrained designs.

Unique Advantages

• Long-term thermal reliability: 10,000-hour rating at 105°C supports stable performance in high-temperature operating conditions.
• Compact footprint: φ5 × 11 mm can and 2.0 mm lead spacing allow dense through-hole placement on power boards and modules.
• Predictable low-loss behavior: Specified tanδ at 120 Hz gives designers measurable AC loss characteristics for frequency-dependent designs.
• Low standby leakage: 5 µA leakage current reduces quiescent power draw in low-power and standby circuits.
• Frequency-flexible ripple handling: Rated ripple currents at 120 Hz and 100 kHz support smoothing across both mains-frequency and higher-frequency switch-mode outputs.
• Regulatory readiness: RoHS compliance simplifies integration into lead-free product assemblies.
