UPTW6330MHD

The UPTW6330MHD from Nichicon is a miniature, radial-lead aluminum electrolytic capacitor in the UPT series engineered for high ripple-current and long-life applications. This 33 µF, 420 V polarized capacitor is optimized for general-purpose and ballast applications where compact size, high-voltage capability and sustained ripple handling are required.

Key value propositions include a high ripple-current rating across frequency, a long endurance specification of 5000 hours at 105°C, and a wide operating temperature range of −40°C to +105°C—enabling reliable performance in compact high-voltage power circuits.

Key Features

• Electrical: 33 µF, 420 V — Rated capacitance 33 µF at 420 V for high-voltage filtering and energy storage in compact designs.
• High ripple-current capability — Rated ripple currents of 270 mA at 120 Hz and 432 mA at 10 kHz; frequency coefficient of rated ripple current increases from 0.80 at 50 Hz up to 1.60 at 10 kHz.
• Long life and endurance — Endurance specified as 5000 hours at 105°C under DC bias plus rated ripple; capacitance change remains within ±20% after the test.
• Wide operating temperature range — −40°C to +105°C to support a broad set of environmental conditions.
• Compact radial-can package — Radial lead, can-style package with 5 mm lead spacing and physical size L: 3.05 × D: 1.25 cm for space-constrained boards.
• Leakage and dissipation — Leakage current defined per series: after 2 minutes at rated voltage and 20°C, I ≤ 0.06CV + 10 (µA); tan δ (for 420 V) specified up to 0.20 max.
• Polarized, general-purpose — Designed as a polarized aluminum electrolytic for general-purpose power and ballast use.
• RoHS compliant — Compliant with the RoHS directive as stated in the product documentation.

Typical Applications

• Lighting Ballasts — Suited for ballast applications requiring compact, high-voltage capacitors with strong ripple-current handling.
• High-voltage power supplies — Filtering and energy storage in compact high-voltage supply rails where 420 V rating and ripple performance are required.
• Industrial control electronics — General-purpose decoupling and smoothing in industrial equipment operating across −40°C to +105°C.

Unique Advantages

• High ripple tolerance: Rated ripple currents at both low and high frequencies reduce the need for larger parallel capacitors in ripple-heavy circuits.
• Verified long-term endurance: 5000 hours at 105°C under rated conditions supports predictable long-life performance in elevated-temperature environments.
• Compact footprint: Small radial-can form factor (L: 3.05 × D: 1.25 cm) and 5 mm lead spacing help save PCB area in space-constrained designs.
• Wide temperature range: −40°C to +105°C operation allows deployment across a broad set of ambient conditions without derating outside specified limits.
• Traceable leakage and dissipation specs: Documented leakage-current formula and tan δ limits provide measurable criteria for design verification and QA.
• RoHS compliant: Meets regulatory material restrictions for easier integration into modern production environments.
