ULD1C101MED

The ULD1C101MED is a miniature radial-lead aluminum electrolytic capacitor from Nichicon’s ULD series, offering 100 µF capacitance at a 16 V rating in a compact can package. It is designed for general-purpose use with a focus on long-life performance in compact power supply designs.

With an operating temperature range of -40°C to +105°C and a rated load life of 10000 hours at +105°C, this capacitor is well suited for LED lighting power supplies and other applications that require sustained performance in elevated-temperature environments. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance at a rated voltage of 16 V, with a tolerance of -20% to +20%.
• Long-life specification — Rated for 10000 hours at +105°C, providing extended service life under high-temperature operating conditions.
• Temperature range — Wide operating range from -40°C to +105°C for reliable performance across demanding thermal environments.
• Package & mounting — Radial lead, can-style package with a compact footprint (L: 1.1 × D: 0.63 cm) and 2.5 mm lead spacing for space-constrained board layouts.
• Ripple performance — Rated ripple current of 147 mA at 120 Hz and 210 mA at 100 kHz for handling AC stress on power rails.
• Polarized design — Polarized electrolytic construction for smoothing and bulk energy storage in DC power circuits.
• RoHS compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• LED lighting power supplies — Provides bulk capacitance and ripple filtering in LED driver circuits where elevated operating temperatures are common.
• Compact power supplies — Small can package and radial leads make it suitable for space-limited power modules and board-level regulators.
• General-purpose smoothing and decoupling — Used in embedded electronics and consumer devices for energy storage and transient suppression on DC rails.

Unique Advantages

• Extended high-temperature durability: 10000-hour rated life at +105°C supports longer maintenance intervals and reduced field replacements.
• Compact footprint: Small L × D dimensions and radial-can construction save PCB space in compact assemblies.
• Reliable ripple handling: Specified ripple currents at both low (120 Hz) and high (100 kHz) frequencies accommodate a range of switching and linear power designs.
• Wide operating temperature: -40°C to +105°C rating enables use across a broad set of environmental conditions.
• Regulatory compliance: RoHS conformity supports environmentally restricted designs and procurement requirements.
