UPA1A822MHD

The UPA1A822MHD is an aluminum electrolytic, radial-lead capacitor from Nichicon's UPA series designed for high-reliability power applications. It combines a compact can-style package with low impedance and high ripple-current capability for demanding switching power supply and general-purpose electronic designs.

Key characteristics include an 8.2 mF capacitance at 10 V, a low impedance of 34 mΩ, and a rugged operating range down to −55 °C and up to 105 °C with a rated lifetime of 5000 hours at 105 °C.

Key Features

• Capacitance & Voltage — 8.2 mF capacitance rated for 10 V DC, suitable for bulk energy storage and smoothing in low-voltage power rails.
• Low Impedance — Specified impedance of 34 mΩ helps minimize voltage ripple and reduces losses in high-current circuits.
• High Ripple Current — Rated ripple current of 2.389 A at 120 Hz and 2.81 A at 10 kHz supports sustained ripple handling in switching supplies.
• Compact Radial Can Package — Radial lead, can-style construction with 7.5 mm lead spacing and overall size L: 3.05 × D: 1.6 cm for space-constrained layouts.
• Wide Temperature & Long Life — Operates from −55 °C to 105 °C with an endurance rating of 5000 hours at 105 °C.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.

Typical Applications

• Switching Power Supplies — Low impedance and high ripple-current capability make it suitable for output smoothing and bulk decoupling in switching regulators.
• General-Purpose Electronics — Provides bulk capacitance and energy storage for a wide range of consumer, industrial, and instrumentation circuits designated as general purpose.
• Power Modules and DC-DC Converters — Compact radial-can form and strong ripple performance support use in modular power stages and converters.

Unique Advantages

• Lower impedance than related UPW series — Enables improved transient response and reduced ESR-related heating where lower impedance is required.
• Measured low impedance (34 mΩ) — Directly reduces AC voltage drop and power dissipation in high-current paths.
• Strong ripple handling — Ripple current ratings of 2.389 A (120 Hz) and 2.81 A (10 kHz) support both low- and high-frequency switching environments.
• Compact, board-friendly footprint — Radial lead can with 7.5 mm lead spacing and a small L × D footprint helps save PCB space in dense assemblies.
• High-temperature endurance — Rated for 5000 hours at 105 °C, providing predictable lifetime performance in thermally stressed applications.
• RoHS compliance — Meets current restricted-substance requirements for global electronics manufacturing.
