ULD1J100MDD

The ULD1J100MDD is a miniature aluminum electrolytic capacitor in Nichicon's ULD series, designed for long-life performance in compact, radial-leaded packages. It delivers 10 µF capacitance at a 63 V rating with radial lead mounting and a polarized can package.

Targeted for general-purpose electronics and power-supply designs—including power supplies for LED lighting—the part combines a small footprint with a long rated life of 10000 hours at +105°C and RoHS compliance.

Key Features

• Electrical Performance — 10 µF capacitance at a 63 V rated voltage with polarization; capacitance tolerance specified as -20% to +20%.
• Long-Life Endurance — Rated for 10000 hours of load life at +105°C, supporting sustained operation in elevated-temperature environments.
• Ripple Current Ratings — Specified ripple handling of 33.6 mA at 120 Hz (low frequency) and 80 mA at 100 kHz (high frequency).
• Temperature Range — Operating range from -40°C to +105°C for broad environmental compatibility.
• Compact Radial Package — Radial lead, can-style package with 2 mm lead spacing and compact dimensions (L: 1.1 × D: 0.5 cm) for space-constrained board layouts.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• LED Lighting Power Supplies — Provides stabilized capacitance and long-term endurance under elevated temperature conditions common in LED driver circuits.
• General-Purpose Power Electronics — Suited for decoupling and smoothing in compact power modules that require a radial-leaded solution.
• Consumer and Industrial Electronics — Useful where a small form factor and long operational life are needed in board-mounted power stages.

Unique Advantages

• Long Rated Life: 10000 hours at +105°C gives designers predictable lifetime performance in high-temperature applications.
• Small Footprint: Compact L: 1.1 × D: 0.5 cm dimensions and 2 mm lead spacing enable placement in dense PCBs and tight power-supply layouts.
• Frequency-Aware Ripple Ratings: Separate ripple current specifications at 120 Hz and 100 kHz allow designers to assess performance across typical switching and low-frequency conditions.
• Wide Operating Temperature: -40°C to +105°C range supports deployment across diverse thermal environments.
• RoHS Compliance: Meets applicable environmental directives for use in regulated product lines.
