UPJ1K331MHD6

The UPJ1K331MHD6 from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can package. It delivers 330 µF capacitance at an 80 V rating, optimized for general-purpose and power-electronics use, including switching power supplies where low impedance and long life are required.

Key value propositions include a compact φ16 × 25 mm can, a wide operating temperature range of -55 °C to +105 °C, and a rated endurance of 5000 hours at 105 °C for robust performance under thermal and ripple stress.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with an 80 V rated voltage and a tolerance of -20% to +20% for predictable energy storage.
• Low Loss — Tangent of loss angle (tan δ) of 0.08 measured at 20 °C, 120 Hz, supporting lower dissipation in AC/ripple conditions.
• Ripple Current Capability — Low-frequency ripple current of 506.92 mA at 120 Hz and high-frequency ripple current of 874 mA at 200 kHz to handle switching and high-frequency workloads.
• Leakage Current — Specified leakage current of 792 µA for predictable standby and bias behavior.
• Reliability / Endurance — Rated for 5000 hours of operation at 105 °C, supporting long-term stability in elevated-temperature environments.
• Mechanical & Mounting — Radial lead mounting with lead spacing of 7.5 mm (±0.5 mm) and a compact size of φ16 × 25 mm for through-hole PCB designs.
• Packaging & Production — Available in Bulk (no terminal forming) or Bag packing; product is in mass production and RoHS compliant.

Typical Applications

• Switching Power Supplies — Low impedance and specified ripple current ratings make this capacitor suitable for smoothing and energy buffering in switched-mode regulators.
• Power Management — Used for bulk energy storage and decoupling in DC/DC converters and power rails operating up to 80 V.
• Industrial Electronics — Reliable operation across -55 °C to +105 °C and a 5000-hour life rating enable use in industrial control and power systems.

Unique Advantages

• Rated for High Voltage: 80 V rating expands design flexibility for higher-voltage power rails without changing capacitor family.
• High Endurance: 5000-hour life at 105 °C provides long-term stability under sustained thermal and electrical stress.
• High-Frequency Capability: Specified ripple performance at both 120 Hz and 200 kHz supports modern switching topologies and high-frequency decoupling.
• Compact Radial Can: φ16 × 25 mm package balances capacitance and board-space efficiency for through-hole assemblies.
• RoHS Compliant: Environmentally compliant construction suitable for assemblies requiring RoHS conformity.
