UPJ1J680MPD

The UPJ1J680MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPJ series designed for general-purpose power applications. It offers a 68 µF capacitance at a 63 V rating with a compact φ8 × 15 mm can and 3.5 mm lead spacing, optimized for through-hole power assemblies.

Designed for switching power supplies and related power-filtering duties, this component combines low impedance characteristics with extended high-temperature endurance to support robust power-rail decoupling and bulk filtering in demanding environments.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low Loss — tanδ specified at 0.08 for the 63 V rating, supporting lower dissipation in AC ripple conditions.
• Predictable Leakage — leakage current consistent with 0.03·C·V (μA), which evaluates to 128.52 µA for this part after 1 minute at 20°C.
• High-Temperature Endurance — rated for 3000 hours at +105°C for the φ8 case size, supporting long-term operation under elevated temperature load.
• Ripple Current Capability — 160.7 mA at 120 Hz and 315 mA at 1 kHz, suitable for filtering and decoupling in power circuits across typical switching frequencies.
• Package & Mounting — radial can package, φ8 × 15 mm body, radial lead mounting with 3.5 mm lead spacing for straightforward through-hole assembly.
• Wide Operating Range — specified for −55°C to +105°C operation, enabling use across varied thermal environments.
• RoHS Compliant — manufactured in accordance with RoHS requirements.
• Production Packaging — supplied in bulk (no terminal forming) / bag packing for mass-production processing.

Typical Applications

• Switching Power Supplies — suited for input/output filtering and energy storage in switching regulators due to low impedance and specified ripple current ratings.
• General-Purpose Power Filtering — used for bulk decoupling and smoothing in a variety of power-supply circuits where a 63 V rating and 68 µF capacitance are required.
• Through-Hole Power Assemblies — radial-lead, φ8 can format and 3.5 mm lead spacing make this capacitor convenient for manual or automated through-hole PCB assembly.

Unique Advantages

• Low-Impedance UPJ Series Behavior: Delivers reduced ESR and dissipation for improved ripple handling, reflected in the part’s specified tanδ and ripple current figures.
• Quantified Leakage Current: Leakage specified by the 0.03·C·V rule yields a calculable 128.52 µA value, simplifying margin and standby-power budgeting.
• High-Temperature Life Rating: 3000-hour endurance at +105°C (φ8 case) provides an established reliability baseline for elevated-temperature applications.
• Compact, Through-Hole Form Factor: φ8 × 15 mm body and standard 3.5 mm lead spacing ease layout in constrained power board designs and through-hole manufacturing flows.
• RoHS Compliance: Environmental compliance supports integration into products targeting regulatory conformance.
