UPW2A151MHD

The UPW2A151MHD is a miniature aluminum electrolytic capacitor from Nichicon's UPW series, offered in a radial lead can for through-hole mounting. It delivers a 150 µF capacitance at a 100 V rating with a compact φ12.5 × 25 mm can and 5 mm lead spacing.

Designed for demanding power-electronics environments, this high-reliability type combines low impedance, measurable ripple-current capability and long endurance for applications such as switching power supplies and automotive electronics (AEC‑Q200 rated).

Key Features

• Capacitance & Voltage — 150 µF rated capacitance with a 100 V working voltage and tolerance of -20% to +20%.
• Low loss / Low impedance — Specified impedance of 260 mΩ and tangent of loss angle (tanδ) of 0.08 measured at 20°C, 120 Hz, supporting efficient ripple handling.
• Ripple current capability — Low-frequency ripple current 461.5 mA (120 Hz) and high-frequency ripple current 710 mA (10 kHz), enabling use in filtered and switching environments.
• Long endurance at elevated temperature — Rated for 7000 hours at 105°C to support long life in high-temperature applications.
• Wide operating temperature — Operating range from -55°C to +105°C for reliable performance across harsh ambient conditions.
• Leakage current & polarization — Leakage current of 450 µA; polarized construction for DC smoothing and energy-storage roles.
• Radial lead package — φ12.5 × 25 mm can with 5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing and supplied in mass-production quantities.
• AEC‑Q200 rated — Qualification suitable for applications requiring the AEC‑Q200 rating included in the product specification.

Typical Applications

• Switching power supplies — Bulk and output filtering where compact, low-impedance capacitance and ripple handling are required.
• Automotive power electronics — Energy storage and decoupling in automotive subsystems leveraging the AEC‑Q200 rating and wide temperature range.
• DC‑DC converters — Input/output smoothing and transient support in compact converter designs.
• Industrial power control — Capacitor for filter networks and hold-up applications in industrial power modules operating up to 105°C.

Unique Advantages

• High-voltage capability in a compact can — 100 V rating in a φ12.5 × 25 mm package enables space-efficient designs that still meet higher-voltage system requirements.
• Measured low loss and impedance — tanδ of 0.08 and 260 mΩ impedance contribute to improved ripple performance and thermal behavior under load.
• Frequency-aware ripple performance — Specified low- and high-frequency ripple currents (461.5 mA at 120 Hz and 710 mA at 10 kHz) help designers size components for both mains-frequency and switching-frequency ripple.
• Extended life at elevated temperature — 7000 hours at 105°C supports reduced maintenance and predictable lifetime in continuous-duty applications.
• Automotive-capable qualification — AEC‑Q200 rating supports deployment in automotive and similarly demanding environments.
• Production-ready supply — Mass-production status and standard radial-lead packaging simplify procurement and assembly planning.
