UCP2G151MHD6

The UCP2G151MHD6 is a high-voltage, miniature aluminum electrolytic capacitor from Nichicon's UCP series designed for long-life, high-reliability applications. It is a polarized, radial-lead can with a rated voltage of 400 V and a capacitance of 150 µF.

With a compact φ18 × 31.5 mm can and a rated lifetime of 10,000 hours at 105°C, this capacitor targets general-purpose high-voltage circuits that require sustained ripple performance and thermal endurance.

Key Features

• Rated Voltage — 400 V Designed for high-voltage circuits using a 400 V nominal rating.
• Capacitance — 150 µF (±20%) 150 µF nominal capacitance with tolerance of -20% to +20% (specified at 120 Hz, 20°C).
• Long Life Endurance Specified for 10,000 hours life at 105°C with defined limits for capacitance, dissipation factor and leakage current after endurance testing.
• Ripple Current Capability Low-frequency ripple: 890 mA at 120 Hz; high-frequency ripple: 1.335 A at 10 kHz — supports a range of ripple conditions across frequencies.
• Loss Tangent (tan δ) tan δ max. 0.24 measured at 20°C, 120 Hz for stable dissipation characteristics.
• Leakage Current Rated leakage current 2,500 µA (typical reference from product table after 1 minute at 20°C).
• Mechanical / Mounting Radial lead, polarized can with dimensions φ18 × 31.5 mm, lead spacing 7.5 mm (±0.5 mm), and available in bulk or bag packing.
• Operating Temperature Range Specified to operate between -40°C and +105°C.
• Production Status Mass production availability from the Nichicon UCP series.

Typical Applications

• High-voltage power circuits — Acts as a bulk storage or smoothing capacitor in 400 V class power stages where long endurance and rated ripple capability are required.
• Industrial electronics — Suitable for general-purpose use in industrial control equipment that operates across -40°C to +105°C and demands stable long-term performance.
• AC/DC and DC/DC converters — Provides ripple handling and energy buffering at both low and high frequencies, supported by specified ripple currents at 120 Hz and 10 kHz.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage circuits without series stacking or complex topologies.
• Long rated life: 10,000 hours at 105°C supports designs targeting extended field service and predictable end-of-life behavior.
• Broad ripple performance: Specified ripple currents at both 120 Hz and 10 kHz help simplify selection for mixed-frequency ripple environments.
• Compact package footprint: φ18 × 31.5 mm can and radial-lead mounting balance capacitance and board-space efficiency for compact power designs.
• Wide operating temperature: -40°C to +105°C supports operation across demanding thermal environments.
• Production-ready packaging: Available in bulk or bag packing for straightforward BOM integration and procurement.
