The ULD2W100MPD is a radial-lead aluminum electrolytic capacitor designed for high-voltage, long-life applications. It provides 10 µF capacitance at a 450 V rating in a compact φ10×20 mm can with 5 mm lead spacing.

Targeted at general-purpose power circuits and LED lighting power supplies, this part delivers long endurance (20,000 hours at +105°C), a wide operating temperature range, and predictable electrical characteristics for stable filtering and energy storage in high-voltage designs.

Key Features

• Electrical Performance — 10 µF capacitance with tolerance ±20% and rated voltage of 450 V, suitable for high-voltage filtering and energy storage.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.24 measured at 20°C, 120 Hz, offering known dissipation behavior for thermal and efficiency calculations.
• Leakage Current — Specified leakage current of 280 µA, allowing designers to budget quiescent current in standby and low-load conditions.
• Ripple Handling — Low-frequency ripple current of 92 mA at 120 Hz and high-frequency ripple current of 174.8 mA at 100 kHz for typical power supply ripple attenuation needs.
• Long Life & Endurance — Life rating of 20,000 hours at +105°C under rated conditions, reflecting suitability for continuous-operation power applications.
• Mechanical & Packaging — Radial lead can (φ10×20L) with 5 mm lead spacing and bulk/bag packing options for manual or automated assembly workflows.
• Environmental Compliance — RoHS compliant.

Typical Applications

• LED Lighting Power Supplies — Long-life 20,000 h endurance and 450 V rating make the capacitor suitable for smoothing and energy storage in LED driver circuits.
• High-Voltage Power Filtering — 10 µF / 450 V combination supports smoothing and decoupling in high-voltage power rails and converters.
• General-Purpose Electronics — Radial-lead format and compact φ10×20 mm size fit space-constrained assemblies requiring reliable long-term performance.

Unique Advantages

• High Voltage Capability: 450 V rating enables use in elevated-voltage power supplies without stacking components.
• Predictable Dissipation: Specified tan δ at 20°C/120 Hz provides known loss behavior for thermal design and efficiency planning.
• Long Endurance at Elevated Temperature: 20,000 hours at +105°C supports continuous-operation applications and reduces periodic replacement needs.
• Compact Radial Can: φ10×20 mm package with 5 mm lead spacing balances board density and ease of through-hole assembly.
• Ripple Current Performance: Defined LF and HF ripple current ratings help ensure reliable operation under switching and mains-frequency ripple conditions.
• RoHS Compliant: Meets RoHS requirements for restricted substances in electronic products.
