ULD1V330MDD

The ULD1V330MDD is a Nichicon ULD-series aluminum electrolytic capacitor in a radial‑lead, miniature can package. It delivers 33 µF capacitance at a 35 V rating with polarized, through‑hole mounting for general‑purpose power and smoothing applications.

Designed for long life operation, the part is specified for 10,000 hours at 105°C and supports both low‑ and high‑frequency ripple environments, making it suitable for compact power supplies including LED lighting drivers and other small form‑factor power circuits.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance (–20% to +20%) at 120 Hz, 20°C.
• Low Loss (tan δ) — tanδ = 0.22 measured at 20°C, 120 Hz, supporting stable AC behavior in filtering and decoupling roles.
• Ripple Current Capability — Low‑frequency ripple current of 71.5 mA at 120 Hz and high‑frequency ripple current of 130 mA at 100 kHz for mixed‑frequency power systems.
• Leakage Current — Specified leakage current of 11.55 µA after rated voltage application, aiding in predictable bias performance.
• Long Life & Temperature Range — Endurance rated 10,000 hours at 105°C with an operating temperature range of –40°C to +105°C.
• Compact Radial Package — Miniature can: diameter φ5 mm × length 11 mm (0.5 × 1.1 cm); radial lead spacing 2 mm (±0.5 mm), suitable for space‑constrained through‑hole layouts.
• Mounting & Packaging — Polarized radial lead mounting; available in bulk (no terminal forming) and bag packing options.
• Environmental Compliance — RoHS compliant.
• Availability Status — Product status: End Of Life.

Typical Applications

• LED Lighting Power Supplies — Suited for smoothing and decoupling in compact LED driver circuits where long life at elevated temperature is required.
• General Purpose Power Filtering — Through‑hole radial mounting for small power supplies and PCB designs requiring reliable bulk capacitance.
• Decoupling in Mixed‑Frequency Circuits — Supports both low‑ and high‑frequency ripple current needs, useful for regulators and converters handling varied ripple spectra.

Unique Advantages

• Long life at elevated temperature: Rated 10,000 hours at 105°C, providing predictable end‑of‑life characteristics for thermal‑stressed designs.
• Compact footprint: φ5 × 11 mm can size and 2 mm lead spacing enable use in tight through‑hole layouts without sacrificing capacitance.
• Measured AC performance: Specified tanδ and ripple current values at standard test conditions (120 Hz / 100 kHz) allow straightforward thermal and ripple budgeting.
• Low leakage: 11.55 µA leakage current supports stable bias conditions and predictable start‑up behavior.
• RoHS compliant: Meets environmental directive requirements for lead‑free assemblies.

Why Choose ULD1V330MDD?

ULD1V330MDD combines a small radial can footprint with long life and defined AC/ripple performance, making it a practical choice for through‑hole power supply designs where space is limited and elevated‑temperature endurance is required. Its specified leakage, tanδ, and ripple current figures help engineers quantify thermal and reliability margins during design.

This part is well suited to designers of compact LED drivers and general‑purpose power circuits who need predictable lifetime behavior, RoHS compliance, and a straightforward radial mounting solution.
