UPJ1C681MHD6

The UPJ1C681MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPJ series, configured as a radial lead can. It provides 680 µF capacitance at a 16 V rating with a compact φ12.5 × 15 mm package and 5 mm lead spacing for through-hole mounting.

Designed for low impedance and long endurance, this part is suited for power supply filtering and general-purpose power applications where sustained ripple handling and wide operating temperature are required.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance for robust bulk energy storage and decoupling.
• Low Loss (tan δ): tanδ 0.16 measured at 20°C, 120 Hz, delivering predictable ESR-related behavior for power designs.
• Ripple Current Capability: Low-frequency ripple current 554.2 mA (120 Hz) and high-frequency ripple current 815 mA (200 kHz) to support AC ripple filtering in switching environments.
• Leakage Current Specification: Leakage current not more than 0.03·C·V (≤ 326.4 µA after 1 minute at 20°C), providing controlled standby losses.
• High Endurance: Load life rated 5000 hours at +105°C under specified stress conditions, supporting long-term reliability in elevated-temperature applications.
• Wide Temperature Range: Operates from −55°C to +105°C to handle demanding environmental conditions.
• Package & Mounting: Radial lead can (φ12.5 × 15 mm), lead spacing 5.0 mm with ±0.5 mm tolerance, available in bulk/no terminal forming or bag packing for flexible assembly options.
• RoHS Compliant: Conforms to RoHS directive requirements.

Typical Applications

• Switching Power Supplies: Low impedance and proven series suitability for smoothing and bulk decoupling on power rails in switch-mode power supplies.
• General Purpose Power Filtering: Bulk energy storage and line filtering in industrial and consumer power circuits where compact size and ripple handling are needed.
• Power Modules and Converters: Local decoupling on DC–DC converters and power modules that require sustained ripple current capacity and high-temperature endurance.

Unique Advantages

• Proven UPJ Series Design: Built on Nichicon's UPJ low-impedance platform, offering application-proven performance for switching power applications.
• High Temperature Endurance: 5000-hour load life at +105°C provides predictable aging and long-term stability in hot operating environments.
• Measured Loss and Leakage Limits: Specified tanδ and leakage current limits (≤ 326.4 µA) make performance predictable for tight power budgets and thermal designs.
• Dual-Frequency Ripple Rating: Specified ripple currents at both 120 Hz and 200 kHz help designers evaluate behavior across mains and switching frequencies.
• Compact Through-Hole Format: φ12.5 × 15 mm radial can with 5 mm lead spacing balances board density with easy manual or wave-solder assembly.
• RoHS Compliance: Environmentally compliant construction for regulated product lines.
