UPJ1E681MPD

The UPJ1E681MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPJ series. This radial-lead, polarized capacitor delivers 680 µF at a 25 V rating in a compact φ10 × 30.5 mm can, optimized for board-level power applications.

Designed for low impedance and robust endurance, the UPJ1E681MPD is intended for general-purpose electronics and specifically suited to switching power supply use where sustained ripple handling and high-temperature life are required.

Key Features

• Capacitance & Voltage: 680 µF at a rated voltage of 25 V with tolerance of -20% to +20%, providing bulk energy storage for DC applications.
• Low Impedance Design: UPJ series construction optimized for low ESR, supporting high ripple currents for power conversion and smoothing tasks.
• High Ripple Current Handling: Rated ripple current of 802.4 mA at 120 Hz and 1.18 A at 200 kHz, enabling effective filtering across low and high frequency regimes.
• Thermal and Endurance Performance: Rated for operation from -55°C to +105°C with a 5000-hour load life at 105°C (as specified for the applicable case sizes), providing long-term stability in elevated-temperature environments.
• Loss Characteristics: Tangent of loss angle (tan δ) of 0.14 measured at 20°C, 120 Hz, supporting predictable AC loss behavior in design calculations.
• Leakage Current: Typical leakage current specified at 510 µA (after rated voltage application), simplifying bias and standby current budgeting.
• Radial Lead Package: φ10 can with 30.5 mm length, 5.0 mm lead spacing (±0.5 mm tolerance) and radial lead form factor for through-hole PCB mounting and manual or wave-solder assembly.
• Packaging Options: Supplied in bulk (no terminal forming) or bag packing to match assembly and inventory requirements.
• Compliance: RoHS compliant.

Typical Applications

• Switching Power Supplies: Low impedance and high ripple current capability make the UPJ1E681MPD suitable for output smoothing and bulk decoupling in switch-mode power supplies.
• General-Purpose Power Electronics: Polarized radial-lead design fits a variety of board-level DC power circuits requiring compact energy storage and reliable high-temperature operation.
• Board-Level Filtering for Through-Hole Assemblies: The radial-lead can and 5 mm lead spacing provide a straightforward solution for through-hole filter stages and power modules.

Unique Advantages

• Long High-Temperature Life: 5000-hour endurance at 105°C (for applicable case sizes) supports designs that must tolerate sustained elevated operating temperatures.
• High Ripple Tolerance Across Frequencies: Specified ripple currents at both 120 Hz and 200 kHz enable use in legacy and modern switching environments without unexpected heating.
• predictable AC Losses: Specified tan δ at measurement conditions (0.14 at 20°C, 120 Hz) allows accurate thermal and loss budgeting in power designs.
• Compact Through-Hole Form Factor: φ10 × 30.5 mm can with standard radial leads simplifies retrofits and designs that require through-hole components.
• Clear Manufacturing Options: Bulk or bag packing supports varied inventory and assembly workflows.
• RoHS Compliance: Meets regulatory requirements for lead-free applications where RoHS conformity is required.
