UPT2P331MHD

The UPT2P331MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UPT series designed for high-ripple, long-life applications. It is a polarized, miniature can-style capacitor offering 330 µF capacitance at 220 V, targeting general-purpose high-voltage circuits where sustained ripple handling and extended operation at elevated temperature are required.

Key value propositions include high ripple-current capability, proven endurance at high operating temperature, and a compact radial package that simplifies through-hole assembly in confined layouts.

Key Features

• Electrical Performance — 330 µF capacitance with ±20% tolerance and a 220 V rated voltage, providing energy storage and filtering for high-voltage circuits.
• High Ripple Current — Rated ripple current of 1.01 A at 120 Hz and 1.616 A at 10 kHz, supporting designs with significant AC ripple stress.
• Long Life & Endurance — Designed for 5,000 hours at 105°C under D.C. bias plus rated ripple current; capacitance, tan δ and leakage meet specified endurance limits after the test.
• Wide Operating Temperature — Specified operation from −40°C to +105°C for robust performance across typical industrial environments.
• Leakage and Dissipation — Leakage current specified as ≤ 0.06CV + 10 μA (after 2 minutes at 20°C); maximum tan δ for 220 V units is 0.12, supporting predictable loss characteristics.
• Compact Radial Can Package — Radial, can-style package with 7.5 mm lead spacing and dimensions L: 4 cm × D: 1.8 cm, enabling dense board layouts and through-hole mounting.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Ballast Circuits — Suited for ballast application where high ripple current capability and high-voltage operation are needed.
• General-Purpose High-Voltage Filtering — Effective for smoothing and energy storage in high-voltage, general-purpose power circuits.
• Industrial Power Electronics — Used in compact, through-hole power assemblies that require long life at elevated temperature and high ripple handling.

Unique Advantages

• High ripple handling: Measured ripple currents of 1.01 A (120 Hz) and 1.616 A (10 kHz) allow the capacitor to support demanding AC load conditions without premature degradation.
• Long-term reliability at elevated temperature: 5,000 hours rated life at 105°C under rated stress provides predictable aging behavior for maintenance planning and product lifetime estimation.
• Predictable leakage and dissipation: Leakage specification (≤ 0.06CV + 10 μA) and tan δ limits give clear electrical bounds for design margining and thermal management.
• Compact radial form factor: Small can dimensions with 7.5 mm lead spacing facilitate dense PCB layouts and easy through-hole assembly in space-constrained designs.
• RoHS compliance: Conforms to RoHS directive requirements for restricted substances, simplifying environmental compliance for assemblies.
