UPA1A272MHD

The UPA1A272MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPA series, rated 2.7 mF at 10 V. It is engineered as a miniature, low-impedance, high-reliability solution for switching power supplies and general-purpose power-filtering applications.

Key technical benefits include a low impedance of 58 mΩ, high allowable ripple current, wide operating temperature range from −55°C to 105°C, and a guaranteed lifetime under high-temperature stress (5,000 hours at 105°C).

Key Features

• Capacitance & Voltage — 2.7 mF (2,700 μF) rated at 10 V, suitable for bulk decoupling and energy storage in low-voltage power rails.
• Low Impedance — Specified impedance of 58 mΩ, reducing ripple voltage and improving transient response in power circuits.
• High Ripple Current — Ripple current ratings of 1.607 A at 120 Hz and 1.89 A at 10 kHz support heavy AC load throughputs typical in switching supplies.
• Thermal & Lifetime Performance — Operates from −55°C to +105°C with endurance specified to 5,000 hours at 105°C (φ12.5 case size), offering predictable long-term behavior under elevated temperature and ripple stress.
• Leakage Current Specification — After 1 minute at rated voltage and 20°C, leakage current ≤ 0.03CV or 4 μA, whichever is greater, for predictable standby loss.
• Electrical Stability — Capacitance tolerance ±20% at 120 Hz, tan δ (10 V) max 0.19 at 120 Hz/20°C, and a low-temperature impedance ratio Z(−55°C)/Z(+20°C) of 3, providing stable performance across environments.
• Compact Radial Package — Radial, can-style package with 5 mm lead spacing and compact dimensions (L: 20 mm × D: 12.5 mm) for space-constrained PCB layouts.
• RoHS Compliant — Meets RoHS directive requirements for reduction of hazardous substances.
• Series Advantages — UPA series notes lower impedance than the UPW series and emphasizes smaller case size with high ripple-current capability.

Typical Applications

• Switching Power Supplies — Bulk decoupling and output smoothing where low impedance and high ripple-handling reduce output ripple and improve regulator stability.
• DC–DC Converters — Input/output filtering for point-of-load converters benefiting from compact size and high ripple current ratings.
• Embedded Power Modules — Energy storage and transient suppression in compact power modules and board-level power conditioning.
• General-Purpose Power Filtering — Hold-up, smoothing, and noise reduction in electronic equipment requiring reliable performance over −55°C to +105°C.

Unique Advantages

• Reduced Ripple Voltage: Low 58 mΩ impedance combined with rated ripple currents lowers AC voltage drop across the capacitor under switching conditions.
• Compact Footprint: Miniature radial-can dimensions enable high-density PCB designs while retaining high ripple capability.
• High-Temperature Endurance: Rated for 5,000 hours at 105°C (φ12.5 case), providing predictable lifetime for demanding thermal environments.
• Predictable Leakage and Loss: Clear leakage current and tan δ specifications aid thermal budgeting and loss calculations during design.
• Broad Operating Range: −55°C to +105°C operation and stable impedance at low temperature support a wide range of deployment conditions.
• Regulatory Compliance: RoHS compliance simplifies material-conformity checks for commercial products.
