ULD2E100MPD

The ULD2E100MPD is a miniature aluminum electrolytic capacitor in Nichicon’s ULD series, designed for long-life operation in compact power circuits. It is a polarized, radial-lead, can-style capacitor with a rated capacitance of 10 µF and a rated voltage of 250 V.

Engineered for applications such as LED lighting power supplies and general-purpose power filtering, the ULD2E100MPD offers a long rated lifetime of 15000 hours at +105°C, RoHS compliance, and a compact footprint for space-constrained designs.

Key Features

• Capacitance & Voltage: 10 µF nominal capacitance with a 250 V rated voltage suitable for higher-voltage filtering and energy-storage tasks.
• Long-Life Thermal Endurance: Rated lifetime of 15000 hours at +105°C, providing extended operating life in elevated-temperature environments.
• Compact Radial Package: Radial can package with 5 mm lead spacing and a compact size (L: 1.25 × D: 1.0 cm) for PCB space savings.
• Operating Range: Specified to operate from −40 °C to +105 °C, addressing a wide range of ambient conditions.
• Ripple Current Capability: 90 mA at 120 Hz (low frequency) and 171 mA at 100 kHz (high frequency) to support DC-bias plus ripple conditions.
• Polarized, Through-Hole Mounting: Polarized aluminum electrolytic design with radial lead mounting for robust through-hole assembly.
• Environmental Compliance: Compliant with the RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• LED Lighting Power Supplies: Provides long-life bulk and smoothing capacitance for driver circuits and LED power modules.
• Compact Power Supplies: Space-constrained AC/DC and DC/DC converters benefit from the small footprint and radial through-hole mounting.
• General-Purpose Power Filtering: Suitable for decoupling and smoothing in industrial and consumer electronic power rails.

Unique Advantages

• Extended High-Temperature Life: 15000 hours at +105°C reduces replacement frequency and maintenance for long-running applications.
• Small Footprint: L: 1.25 × D: 1.0 cm dimensions help optimize board layout in compact devices.
• High Voltage Handling: 250 V rating supports higher-voltage circuits without additional series components.
• Robust Through-Hole Mounting: Radial leads and can package offer mechanical stability for industrial assembly processes.
• Frequency-Indexed Ripple Performance: Specified ripple current at both 120 Hz and 100 kHz enables selection for both low- and high-frequency ripple conditions.
• RoHS Compliant: Meets environmental regulatory requirements for modern electronic products.
