UPA0J822MHD

The UPA0J822MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPA series, engineered for miniature, high-reliability power applications. It combines low impedance and high ripple-current capability in a compact can-style package, making it suitable for switching power supplies and other compact power systems.

Key value comes from its low measured impedance and elevated ripple-current ratings, paired with a wide operating temperature range and extended high-temperature endurance for sustained performance in demanding environments.

Key Features

  8.2 mF (8200 μF) rated at 6.3 V, with a tolerance of ±20% at 120 Hz, 20°C.
• Low Impedance 
  Impedance specified at 38 mΩ, supporting improved power rail stability and transient performance.
• High Ripple Current 
  Rated ripple current of 2.346 A at 120 Hz and 2.76 A at 10 kHz, enabling effective smoothing in switching applications.
• Compact Radial Can 
  Radial-lead, can-style package with lead spacing of 7.5 mm and physical dimensions L: 2.5 × D: 1.6 cm for space-constrained layouts.
• Wide Temperature & Endurance 
  Operating temperature range from −55°C to +105°C and a specified lifetime of 5000 hours at 105°C.
• Polarized Type 
  Designated as a polarized electrolytic capacitor for DC power applications.
• RoHS Compliant 
  Manufactured in accordance with RoHS requirements.

Typical Applications

• Switching Power Supplies 
  Provides bulk filtering and ripple smoothing where low impedance and high ripple capability are required.
• General-Purpose Power Filtering 
  Used for decoupling and energy storage in compact power assemblies and board-level power rails.
• Compact Power Modules 
  Sized for high-density designs that demand a balance of ripple handling, low ESR, and small footprint.

Unique Advantages

• Low ESR/Impedance: The 38 mΩ impedance supports tighter voltage regulation and reduced heat generation at the capacitor.
• High Ripple Handling: Ripple current ratings of 2.346 A (120 Hz) and 2.76 A (10 kHz) let the capacitor manage AC stress typical in switching converters.
• Small Form Factor: Compact radial-can dimensions (L: 2.5 × D: 1.6 cm) and 7.5 mm lead spacing help minimize board real estate in dense layouts.
• Extended High-Temperature Endurance: Specified lifetime of 5000 hours at 105°C for reliable operation under sustained thermal stress.
• Wide Operating Range: Rated for −55°C to +105°C to accommodate a broad set of environmental conditions.
• Regulatory Compliance: RoHS-compliant construction supports regulatory and environmental requirements.
