UPA0J103MHD

The UPA0J103MHD is a Nichicon UPA series aluminum electrolytic capacitor designed for miniature, radial‑lead installations where low impedance and high reliability are required. It is a polarized, radial‑lead can intended for switching power supplies and general‑purpose power applications.

With a capacitance of 10 mF at 6.3 V, low measured impedance, and high ripple current capability, this part targets designs that need bulk energy storage and effective decoupling in compact packages while meeting RoHS requirements.

Key Features

• Capacitance & Voltage: 10 mF nominal capacitance at a rated voltage of 6.3 V with a tolerance of ±20%.
• Low Impedance: Rated impedance of 34 mΩ, supporting low‑loss filtering and fast transient response in power rails.
• High Ripple Current: Ripple handling of 2.389 A at 120 Hz and 2.81 A at 10 kHz, enabling robust operation in switching environments.
• Wide Temperature Range: Operation from –55°C to +105°C for use across diverse thermal conditions.
• Long Endurance: Rated lifetime of 5000 hours at 105°C, supporting extended service in continuous‑duty power applications.
• Radial Lead Package: Radial, can‑style package with 7.5 mm lead spacing and compact dimensions (L: 3.05 × D: 1.6 cm) for through‑hole mounting.
• Compliance: RoHS compliant, aligning with environmental requirements.
• Series Advantages: UPA series characteristics include smaller case size and lower impedance compared to UPW, with design focus on high ripple current performance.

Typical Applications

• Switching Power Supplies: Bulk smoothing and output filtering in switching regulators where low impedance and high ripple endurance improve voltage stability.
• Power Rail Decoupling: Local energy storage and transient suppression on low‑voltage DC rails to support converter and regulator performance.
• General‑Purpose Power Systems: Capacitor for general‑purpose smoothing and filtering in industrial and consumer electronic power circuits requiring a compact, high‑capacitance radial device.

Unique Advantages

• Low ESR/Impedance: 34 mΩ impedance reduces power loss and improves transient response in high‑current switching scenarios.
• Compact, High‑Capacitance Package: 10 mF in a small radial can (L: 3.05 × D: 1.6 cm) helps reduce board space compared with larger alternatives.
• Proven Ripple Handling: Specified ripple current values at both 120 Hz and 10 kHz support a range of switching frequencies and real‑world regulator conditions.
• Extended High‑Temp Life: 5000 hours at 105°C provides predictable lifetime for continuous‑duty power designs.
• Through‑Hole Robustness: Radial lead configuration and 7.5 mm lead spacing offer secure mechanical mounting for modules and power assemblies.
• RoHS Compliant: Meets environmental directive requirements for restricted substances.
