UPJ0J123MHD

The UPJ0J123MHD is a radial-leaded aluminum electrolytic capacitor from Nichicon’s UPJ series, offering 12,000 µF capacitance at a 6.3 V rated voltage. It is designed for power filtering and energy-storage duties where high bulk capacitance, robust ripple handling and long operational life are required.

With a low-impedance construction for switching power supply environments, a wide operating temperature range of -55 °C to 105 °C and a rated endurance of 5,000 hours at 105 °C, this part addresses demanding general-purpose power applications that need sustained performance over long duty cycles.

Key Features

• High Capacitance, Low Voltage: 12,000 µF capacitance at a 6.3 V rating provides substantial bulk energy storage for low-voltage power rails and filtering tasks.
• Low Impedance for Switching Supplies: Engineered for low impedance behavior (UPJ series), making it suitable for smoothing and decoupling in switching power supplies.
• High Ripple Current Capability: Rated low-frequency ripple current of 2.277 A at 120 Hz and high-frequency ripple current of 2.53 A at 200 kHz to support continuous ripple stress in power designs.
• Long Endurance: 5,000 hours rated life at 105 °C under specified conditions, supporting long-term reliability in thermal-stressed environments.
• Temperature Range: Wide operating range from -55 °C to 105 °C for broad environmental suitability.
• Radial Lead Can Package: Radial, can-style package with lead spacing 7.5 mm (±0.5 mm) and physical size φ18 × 35.5 mm (L: 3.55 cm × D: 1.8 cm), ideal for through-hole power assemblies.
• Electrical Characteristics: Capacitance tolerance ±20% and measured dissipation factor (tan δ) of 0.44 at 20 °C, 120 Hz; leakage current listed at 2,268 µA.
• Compliance & Packaging: RoHS compliant; available in bulk (no terminal forming) and bag packing. Product is in mass production.

Typical Applications

• Switching Power Supplies: Bulk smoothing and output filtering where the UPJ0J123MHD’s low impedance and high ripple current capability reduce voltage ripple on DC rails.
• DC-DC Converters: Energy storage and decoupling on low-voltage converter outputs to stabilize transient responses and support sustained load currents.
• Industrial Power Modules: Through-hole power assemblies that require long life at elevated temperatures and robust ripple handling for continuous operation.

Unique Advantages

• Substantial Bulk Capacitance: 12,000 µF provides large charge reserve to smooth voltage excursions and support transient load events.
• Designed for Ripple Stress: Specified ripple currents at both low and high frequencies allow designers to assess thermal and lifetime behavior under realistic power‑system conditions.
• Long Thermal Endurance: 5,000-hour rating at 105 °C offers predictable service life in hot environments, reducing maintenance and replacement cycles.
• Wide Temperature Operation: -55 °C to 105 °C range enables deployment across a broad set of environmental conditions without compromising basic performance limits.
• Through-Hole Form Factor: Radial lead can with defined lead spacing simplifies placement in legacy and serviceable power assemblies.
• Regulatory Compliance: RoHS compliance supports use in designs targeting restricted-substance requirements.
