UPJ0J331MED

The UPJ0J331MED is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPJ series. It is a radial-lead, polarized capacitor specified at 330 µF and 6.3 V, designed for general-purpose power applications.

With a compact φ6.3 × 15 mm can and performance characteristics aimed at switching power supplies, this part targets board-level power filtering and decoupling where a low-impedance, reliable electrolytic capacitor is required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with tolerance of -20% to +20% at a rated voltage of 6.3 V.
• Loss Angle (tan δ) — tanδ (DF) 0.22 measured at 20°C, 120 Hz, providing a quantifiable dissipation factor for design calculations.
• Ripple Current Ratings — Low-frequency ripple current 179.8 mA at 120 Hz; high-frequency ripple current 310 mA at 200 kHz, enabling performance characterization across common switching frequencies.
• Leakage Current — Specified leakage current of 62.37 µA measured under rated conditions.
• Reliability & Endurance — Rated life/endurance of 2000 hours at 105°C to support elevated-temperature operation.
• Thermal Range — Operating temperature range from -55°C to +105°C for use across a wide range of ambient conditions.
• Package & Mounting — Miniature radial-can package: φ6.3 × 15 mm (L); lead spacing 2.5 mm with 0.5 mm tolerance; available in bulk (no terminal forming) or bag packing.
• RoHS Compliance — Product is RoHS compliant.

Typical Applications

• Switching Power Supplies — UPJ series design emphasis on low impedance makes this part suitable for input/output filtering and decoupling in switching regulators.
• General Purpose Power Filtering — 330 µF / 6.3 V rating and defined ripple current values support board-level smoothing and bulk decoupling in general-purpose circuits.
• Radial-Lead PCB Mounting — Compact φ6.3 × 15 mm radial package with 2.5 mm lead spacing for through-hole assemblies that require a small footprint electrolytic solution.

Unique Advantages

• Specified ripple performance at multiple frequencies: Published ripple current values at 120 Hz and 200 kHz allow designers to evaluate thermal and ripple performance across low- and high-frequency regimes.
• Quantified dissipation factor: tanδ of 0.22 (20°C, 120 Hz) provides a clear parameter for loss and heating estimates in power designs.
• Broad operating temperature: -55°C to +105°C range supports a variety of ambient environments and thermal requirements.
• Compact radial can: φ6.3 × 15 mm size and 2.5 mm lead spacing offer a small form factor for space-constrained through-hole applications.
• RoHS compliant: Meets RoHS directive requirements for lead-free assemblies and environmental compliance.
• Clear endurance rating: 2000 hours at 105°C gives a defined lifetime metric for reliability planning and thermal budgeting.

Why Choose UPJ0J331MED?

UPJ0J331MED combines the UPJ series’ focus on low impedance with explicit, engineer-focused specifications: 330 µF at 6.3 V, defined tanδ, measured ripple currents at both low and high frequencies, and a published 2000-hour endurance at 105°C. These measurable parameters make the part straightforward to evaluate for thermal, stability, and ripple-handling requirements.

This capacitor is well suited to designers needing a compact radial-lead electrolytic for switching power supplies and general-purpose power filtering, where documented ripple performance, leakage, and dissipation characteristics are important for system-level reliability and thermal design.
