UPJ0J103MHD

The UPJ0J103MHD is a Nichicon UPJ series aluminum electrolytic capacitor in a radial‑lead can, offering 10000 µF capacitance at a 6.3 V rating. It is designed for general-purpose power applications and is ideally suited for use in switching power supplies where high capacitance, ripple tolerance and long life are required.

Key value comes from its combination of high capacitance, substantial ripple‑current capability, low loss characteristics and a long endurance rating of 5000 hours at 105°C, making it suitable for demanding power‑filtering roles.

Key Features

• Large Capacitance: 10000 µF (10 mF) provides bulk energy storage and smoothing for power rails and supply hold‑up.
• Rated Voltage & Polarization: 6.3 V rated, polarized device for DC power applications.
• Low Impedance / High Ripple Handling: Low-frequency ripple current 2.223 A (120 Hz) and high-frequency ripple current 2.47 A (1 kHz) support heavy ripple conditions in power supplies.
• Loss and Leakage: Tangent of loss angle (tanδ) specified as 0.4 (measured at 20°C, 120 Hz) and leakage current 1890 µA as provided for this part.
• Long Endurance: Rated for 5000 hours at 105°C under specified load-life conditions, supporting reliable operation in elevated temperatures.
• Wide Operating Temperature: −55°C to +105°C operation accommodates a broad range of thermal environments.
• Radial Can Package: φ16 × 40L can with 7.5 mm lead spacing (±0.5 mm), radial lead mounting for through‑hole PCB assembly; available in bulk/bag packing.
• Compliance & Availability: RoHS‑compliant and listed as mass production.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering in switch‑mode power supplies, leveraging the part’s high capacitance and ripple‑current capability.
• Power Supply Filtering — General-purpose DC power filtering where long life at elevated temperature and substantial ripple handling are required.
• High‑ripple Power Modules — Use in modules and assemblies that see continuous ripple current, supported by the specified ripple current ratings and endurance.

Unique Advantages

• High Energy Density: 10000 µF capacitance in a compact φ16 can reduces the number of parts needed for bulk storage and smoothing.
• Designed for Ripple Stress: Specified ripple currents at 120 Hz and 1 kHz allow designers to size the capacitor specifically for real‑world switching and ripple conditions.
• Proven Endurance: 5000 hours at 105°C demonstrates long operational life under thermal stress, helping to improve system reliability.
• Clear Electrical Characterization: Provided tanδ and leakage current figures enable accurate thermal and leakage budgeting in designs.
• Through‑Hole Robustness: Radial lead, can‑style package with defined lead spacing simplifies mounting and mechanical retention for power boards.
• Regulatory Compliance: RoHS‑compliant construction supports environmental requirements.
