UPA1A562MHD

The UPA1A562MHD is a miniature aluminum electrolytic capacitor in Nichicon’s UPA series, engineered for low impedance and high reliability in power electronics. It is a radial-lead, polarized can-style capacitor designed specifically for switching power supplies and general-purpose power filtering applications.

Key value propositions include a compact footprint with low impedance (32 mΩ), high ripple-current capability, and extended high-temperature life, making it suitable where stable power decoupling and compact board space are important.

Key Features

• Capacitance & Voltage: 5.6 mF capacitance rated at 10 V for bulk energy storage and decoupling on low-voltage rails.
• Low Impedance: 32 mΩ impedance supports low-voltage ripple and improved transient response in power circuits.
• High Ripple Current: Rated ripple current of 2.499 A at 120 Hz and 2.94 A at 10 kHz to handle switching supply ripple across common frequencies.
• Temperature & Lifetime: Operating temperature range –55°C to +105°C with a rated lifetime of 5000 hours at 105°C.
• Package & Mounting: Radial lead, can-style package with 5 mm lead spacing and compact dimensions (L: 3.55 × D: 1.25 cm) for board-level installations.
• Tolerance & Polarization: Capacitance tolerance of ±20% and polarized construction appropriate for DC power applications.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies: Bulk and output filtering where the UPA1A562MHD’s low impedance and high ripple capability reduce voltage ripple and support regulator stability.
• General-Purpose Power Filtering: Board-level decoupling and energy storage for low-voltage rails in compact electronic assemblies.
• Compact Power Modules: Space-constrained power designs that benefit from the capacitor’s small case size combined with substantial ripple-handling.

Unique Advantages

• Low impedance for improved regulation: 32 mΩ impedance helps reduce ripple voltage and improves transient response in switching circuits.
• High-frequency ripple capability: 2.94 A ripple rating at 10 kHz supports modern switching frequencies encountered in DC‑DC converters and power supplies.
• Compact board footprint: Small can-style radial package with 5 mm lead spacing and a 3.55 × 1.25 cm size enables space-efficient designs.
• Wide temperature tolerance: –55°C to +105°C rating allows operation across broad thermal environments common in industrial electronics.
• Long high-temperature life: 5000 hours at 105°C provides predictable endurance for sustained high-temperature operation.
• Regulatory compliance: RoHS compliance supports use in markets requiring restricted-substance conformance.
