UPJ1J681MHD

The UPJ1J681MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPJ series, offered in a radial-lead can package. It delivers 680 µF capacitance at a 63 V rating and is optimized for applications requiring low impedance and sustained performance under elevated temperature and ripple stress.

Designed for general-purpose power electronics and switching power supply use, the part combines high ripple-current handling and long endurance—specified for 5000 hours at 105°C—making it suitable where sustained stability and thermal resilience are required.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with tolerance of -20% to +20% at 120 Hz, 20°C; rated for 63 V operation.
• Low Dissipation Factor — tanδ of 0.08 measured at 20°C, 120 Hz, supporting efficient AC performance and reduced heating in service.
• High Ripple Current Capability — Low-frequency ripple current 1.156 A (120 Hz) and high-frequency ripple current 1.7 A (200 kHz) for demanding power applications.
• Leakage Current — Specified leakage current of 1285.2 µA.
• Long Endurance — Rated endurance of 5000 hours at 105°C, supporting extended service life under rated conditions.
• Operating Temperature Range — Wide operating range from -55°C to +105°C for use across varied thermal environments.
• Package & Mounting — Radial, can-style package with dimensions φ16 × 30.5 mm (diameter × length) and 7.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Compliance — RoHS compliant.

Typical Applications

• Switching Power Supplies — Low impedance and high ripple-current capability make this capacitor suitable for bulk filtering and output smoothing in switching regulators.
• General-Purpose Power Filtering — 63 V rating and 680 µF capacitance provide energy storage and decoupling in a wide range of power-electronics circuits.
• Through-Hole Radial Designs — Radial-lead can package suits PCB-mounted power assemblies where a compact, serviceable electrolytic is required.

Unique Advantages

• High Thermal Endurance: 5000-hour rating at 105°C supports prolonged operation in elevated temperature environments, reducing maintenance frequency.
• Robust Ripple Handling: Specified low- and high-frequency ripple currents (1.156 A at 120 Hz, 1.7 A at 200 kHz) enable reliable performance under dynamic load conditions.
• Measurable Low Loss: tanδ of 0.08 (20°C, 120 Hz) indicates low dissipation factor for improved efficiency and lower temperature rise during operation.
• Compact Radial Can: φ16 × 30.5 mm package with 7.5 mm lead spacing fits space-constrained PCB power designs while preserving serviceability.
• Production-Ready Supply: Product status is mass production with bulk and bag packing options to support prototype and volume builds.
• RoHS Compliance: Meets environmental requirements for regulated substances.
