UCS2D151MND9

The UCS2D151MND9 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UCS series. It is a radial-lead, polarized capacitor specified at 150 µF and 200 V, designed for general-purpose electronic applications requiring high ripple tolerance and long operational life.

With a rated lifetime of 10000 hours at 105°C, a compact φ10 × 50 mm can, and high ripple current capability, this part is suited for power supply and ballast applications and other circuits where sustained thermal and electrical stress are expected.

Key Features

• Electrical Characteristics 150 µF capacitance with ±20% tolerance and rated voltage of 200 V; polarized design for DC filtering and energy storage.
• High Ripple Current Low-frequency ripple current 830 mA (120 Hz) and high-frequency ripple current 1.66 A (100 kHz), allowing effective smoothing under demanding ripple conditions.
• Long Life / Endurance Rated for 10000 hours at 105°C under DC bias plus rated ripple current, providing extended service life in elevated-temperature environments.
• Low Loss and Leakage Dissipation factor (tan δ) 0.20 (measured at 20°C, 120 Hz) and leakage current specified at 1300 µA, supporting stable performance in power circuits.
• Compact Radial Package Can size φ10 × 50 mm with 5.0 mm lead spacing (±0.5 mm); radial-lead mounting simplifies through-hole PCB assembly and retrofit designs.
• Operating Range & Compliance Operating temperature range −40°C to +105°C and RoHS compliant packaging options (Bulk/Bag) for regulatory alignment.

Typical Applications

• Power Supplies — Output filtering and bulk energy storage in power supply modules where high ripple current and long life are required.
• Ballast Circuits — Suited for ballast applications as indicated in UCS series documentation, providing reliable operation under continuous load.
• General-Purpose Electronics — Through-hole designs needing a compact, high-reliability polarized capacitor for DC filtering and decoupling.

Unique Advantages

• High ripple handling: Rated ripple currents of 830 mA (120 Hz) and 1.66 A (100 kHz) reduce heat buildup and improve filtering performance in ripple-intensive circuits.
• Extended elevated-temperature life: 10000 hours at 105°C supports longer maintenance intervals and predictable aging in hot-payload applications.
• Compact, serviceable package: φ10 × 50 mm radial can with 5 mm lead spacing fits space-constrained through-hole PCBs and retrofit designs.
• Stable loss and leakage: tan δ of 0.20 (20°C, 120 Hz) and specified leakage current provide predictable electrical behavior for power-design margining.
• Regulatory alignment: RoHS compliant to support environmentally restricted markets and procurement requirements.
