UPT2G330MHD

The UPT2G330MHD is an aluminum electrolytic capacitor in a radial can package designed for high-voltage, high-ripple applications. This polarized 33 µF, 400 V component offers a compact footprint and is intended for general-purpose electronic circuits, with specific suitability for ballast applications.

Engineered for durability, the UPT2G330MHD combines elevated ripple-current capability with long-life endurance at elevated temperatures, making it a practical choice where sustained performance under stress is required.

Key Features

• Capacitance & Voltage — Rated at 33 µF and 400 V, providing a high-voltage energy storage option for designs requiring elevated DC bus handling.
• High ripple current capability — Rated ripple current of 290 mA at 120 Hz and 464 mA at 10 kHz, supporting circuits with significant AC ripple on the DC bias.
• Long-life endurance — Specified for 5000 hours at 105 °C under DC bias plus rated ripple current; capacitance change is within ±20% after endurance testing.
• Wide operating temperature range — Operational from −40 °C to +105 °C to accommodate a broad range of environmental conditions.
• Compact radial-can package — Radial lead can with lead spacing of 5.0 mm and dimensions L: 3.05 × D: 1.25 cm, enabling space-efficient PCB placement.
• Leakage and dissipation specifications — Leakage current is specified as not more than 0.06CV+10 µA (after 2 minutes at 20 °C); tan δ for the 400 V rating is specified (max. 0.15), providing predictable dissipation behavior.
• RoHS compliant — Meets RoHS directive requirements for restricted substances.
• Polarized, radial-lead mounting — Standard polarized construction with radial leads for through-hole assembly.

Typical Applications

• Lighting ballasts — Suited for ballast circuits that require high ripple current handling and long operating life.
• High-voltage general-purpose electronics — Used where a compact 400 V polarized capacitor is needed for energy storage or smoothing under DC bias.
• Circuits exposed to elevated temperatures — Applicable in designs that must endure continuous operation at temperatures up to 105 °C.

Unique Advantages

• High ripple tolerance: Rated ripple currents (290 mA at 120 Hz; 464 mA at 10 kHz) reduce stress on the capacitor in AC-superimposed DC environments.
• Proven long-life performance: 5000 hours at 105 °C endurance rating ensures predictable capacitance retention and leakage behavior over extended service periods.
• Compact form factor: Small radial-can dimensions (3.05 × 1.25 cm) and 5 mm lead spacing support space-constrained PCB layouts.
• Wide operating range: −40 °C to +105 °C rating covers many industrial and commercial ambient conditions.
• Measurable electrical limits: Clear leakage current and tan δ specifications provide designers with verifiable dissipation and leakage bounds for system-level calculations.
• Regulatory compliance: RoHS compliant to support restricted-substance requirements.
