UPJ1C122MHD

The UPJ1C122MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPJ series, offering 1200 µF capacitance at a 16 V rating. It combines low impedance construction and robust endurance for general-purpose power applications, especially where switching power supply filtering and bulk energy storage are required.

Designed for demanding thermal conditions, this part is specified for operation from -55°C to +105°C and is rated for 5000 hours at +105°C, providing a reliable solution for embedded power systems and power-management circuits.

Key Features

• Electrical Performance 1200 µF capacitance at 16 V with ±20% tolerance, offering substantial bulk capacitance for smoothing and decoupling in power designs.
• Loss and Dissipation Tangent of loss angle (tan δ) 0.16 measured at 20°C, 120 Hz, with leakage current specified at 576 µA—data useful for loss budgeting and standby power estimates.
• Ripple Current Capability Low-frequency ripple current 1.025 A (120 Hz) and high-frequency ripple current 1.25 A (200 kHz), supporting both mains-frequency and high-frequency switching applications.
• Reliability & Endurance Load-life endurance of 5000 hours at +105°C, reflecting the UPJ series’ low-impedance, high-reliability design for continuous operation under thermal stress.
• Temperature Range Rated for -55°C to +105°C, suitable for a wide range of operating environments.
• Mechanical & Mounting Radial lead, polarized can package with dimensions φ12.5 × 20 mm and lead spacing 5.0 mm (±0.5 mm), supplied in bulk or bag packing (no terminal forming).
• Compliance RoHS compliant, aligned with common environmental requirements.

Typical Applications

• Switching Power Supplies Low-impedance construction and rated ripple currents make the capacitor suitable for output filtering and bulk storage in DC–DC converters and switching regulators.
• Power Management Modules Provides bulk decoupling and transient energy support for power rails in embedded systems and board-level power modules.
• Consumer and Industrial Electronics General-purpose smoothing and energy storage where a compact radial electrolytic is required and long endurance at elevated temperature is needed.

Unique Advantages

• High Capacitance Density: 1200 µF in a φ12.5 × 20 mm can delivers substantial bulk capacitance in a compact form factor, reducing board area for energy storage.
• Designed for Switching Environments: Specified ripple current at both 120 Hz and 200 kHz supports mains-frequency filtering and high-frequency switching applications alike.
• Long Endurance at Elevated Temperature: 5000 hours at +105°C provides predictable life performance for continuous-duty power systems.
• Measured Loss Characteristics: tan δ specified at 0.16 (20°C, 120 Hz) and a defined leakage current (576 µA) enable precise thermal and energy-loss calculations in designs.
• Practical Packaging: Radial lead format with standard 5 mm lead spacing and availability in bulk or bag packing simplifies through-hole assembly and handling.
• Regulatory Compliance: RoHS compliance supports designs targeting regions with restricted substance requirements.
