UPA1A682MHD

The UPA1A682MHD is a radial‑lead aluminum electrolytic capacitor from Nichicon's UPA series designed for compact, high‑ripple power applications. It delivers 6.8 mF capacitance at a 10 V rating in a small can package optimized for switching power supplies and general‑purpose power filtering.

Built for low impedance and long operational life, this part combines a compact footprint and high ripple current capability with a wide operating temperature range and RoHS compliance.

Key Features

• Capacitance & Rated Voltage — 6.8 mF nominal capacitance with a 10 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low Impedance — Rated impedance of 38 mΩ for improved ripple handling and lower voltage drop under load.
• High Ripple Current — Supports 2.346 A at 120 Hz and 2.76 A at 10 kHz, enabling effective smoothing in switching power stages.
• Compact Radial Package — Radial can with lead spacing of 7.5 mm and physical size L: 2.5 × D: 1.6 cm for space‑constrained board layouts.
• Extended Temperature & Lifetime — Operates from −55°C to +105°C with an expected lifetime of 5000 hours at 105°C.
• Polarized, Through‑Hole Mounting — Polarized electrolyte design with radial lead mounting suitable for conventional through‑hole assembly.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Frequency Performance — For capacitances in the 1200–10000 μF range, frequency coefficients apply (e.g., 0.85 at 120 Hz and 1.00 at 10 kHz), supporting AC ripple at higher switching frequencies.

Typical Applications

• Switching Power Supplies — Bulk and output smoothing where compact, low‑impedance capacitors reduce ripple and improve regulator stability.
• DC–DC Converters — Input/output decoupling and energy buffer in step‑down/up converter stages that demand high ripple endurance.
• Power Modules & Industrial Electronics — Local energy storage and filtering in power assemblies that operate across −55°C to +105°C.
• General Purpose Power Filtering — Board‑level bulk capacitance for consumer and industrial power systems requiring reliable, long‑life electrolytic performance.

Unique Advantages

• Low impedance for better ripple suppression: 38 mΩ impedance minimizes voltage ripple at the capacitor terminals, improving power rail quality.
• High ripple current capability: Specified ripple currents of 2.346 A (120 Hz) and 2.76 A (10 kHz) allow the part to handle dynamic loads in switching environments.
• Compact, space‑saving form factor: Short radial can (L: 2.5 × D: 1.6 cm) and 7.5 mm lead spacing reduce board area compared with larger electrolytic options.
• Long operational life at elevated temperature: Rated for 5000 hours at 105°C, supporting extended reliability in hot operating conditions.
• Wide operating temperature range: −55°C to +105°C covers a broad set of environmental requirements for power electronics.
• RoHS compliant: Meets current RoHS directives for lead‑free environmental requirements.
