UCS2C151MHD

The UCS2C151MHD is a high-reliability miniature aluminum electrolytic capacitor from Nichicon’s UCS series. It is a radial lead, polarized capacitor specified at 150 µF and 160 V, designed for applications that require high ripple handling and long operational life.

Typical use cases include power supply and ballast applications as well as general-purpose circuits that demand elevated temperature endurance and stable performance over extended service life.

Key Features

• Electrical — Rated capacitance 150 µF with ±20% tolerance; rated voltage 160 V; polarized design for DC power applications.
• Losses / Dissipation — Tangent of loss angle (tan δ) 0.20 measured at 20°C, 120 Hz, enabling predictable AC loss behavior.
• Ripple Current Performance — Low-frequency ripple current 945 mA at 120 Hz and high-frequency ripple current 1.89 A at 100 kHz, supporting both low- and high-frequency power filtering.
• Leakage Current — Specified leakage current 1060 µA (after 1 minute at 20°C), allowing designers to budget standby and bias currents.
• Reliability & Lifetime — Endurance rated for 10,000 hours at 105°C; part of the UCS series long-life products.
• Mechanical & Packaging — Compact φ16 × 20 mm can with 7.5 mm lead spacing; available in bulk (no terminal forming) or bag packing for flexible procurement and assembly.
• Temperature Range & Compliance — Operating temperature range −40°C to +105°C; RoHS compliant.

Typical Applications

• Power Supplies — Bulk filtering and smoothing in DC power supplies where 160 V working voltage and high ripple current capability are required.
• Ballasts — Designed for ballast applications referenced in the UCS series datasheet, providing stability and long life at elevated temperatures.
• General-Purpose Electronics — Polarized decoupling and energy storage in general-purpose circuits requiring a compact high-voltage electrolytic capacitor.

Unique Advantages

• High ripple-current capacity: Specify 945 mA at 120 Hz and 1.89 A at 100 kHz to handle both low- and high-frequency ripple in power conversion circuits.
• Long operational life: Rated for 10,000 hours at 105°C, supporting designs that require extended maintenance intervals and predictable end-of-life behavior.
• Compact radial package: φ16 × 20 mm can and 7.5 mm lead spacing make it suitable for space-constrained PCB layouts while retaining high-voltage capability.
• Predictable loss characteristics: tan δ = 0.20 (20°C, 120 Hz) provides a clear basis for thermal and dissipation design decisions.
• Procurement flexibility: Available in bulk (no terminal forming) or bag packing to match manufacturing and assembly preferences.
• Regulatory compliance: RoHS compliant, simplifying environmental compliance for end products.
