ULD1J330MED

The ULD1J330MED from Nichicon is a miniature, radial‑lead aluminum electrolytic capacitor in the ULD long‑life series. It is a polarized, general‑purpose capacitor engineered for compact power circuits and applications requiring extended load life.

Key value propositions include a 33 µF capacitance at 63 V rating, long life endurance of 10000 hours at +105°C, compact radial can packaging, and RoHS compliance, making it well suited for LED power supplies and other space‑constrained power designs.

Key Features

• Electrical Rating — 33 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance (−20% to +20%).
• Long Life Endurance — Rated for 10000 hours at +105°C under specified load life conditions, reflecting the ULD series long‑life design.
• Wide Operating Temperature — Specified operating range from −40°C to +105°C for broad ambient conditions.
• Ripple Current Capability — Low‑frequency ripple current of 93.5 mA at 120 Hz and high‑frequency ripple current of 170 mA at 100 kHz.
• Compact Radial Package — Radial can with radial lead mounting, lead spacing 2.5 mm, and size L: 1.1 × D: 0.63 cm; seated height 1.1 cm maximum.
• Polarized Design — Polarized aluminum electrolytic construction for DC power filtering and decoupling applications.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• LED Lighting Power Supplies — Suited for power supply filtering and smoothing in LED drivers, per the product description.
• General‑Purpose Power Supplies — Used for decoupling, bulk storage and smoothing in compact power circuits.
• Space‑Constrained Board Designs — Miniature radial can and small footprint fit compact or densely populated PCBs.

Unique Advantages

• Extended Load Life: 10000 hours at +105°C provides design confidence for long‑lived power supplies and LED fixtures.
• Compact Form Factor: Small can size (L: 1.1 × D: 0.63 cm) and 2.5 mm lead spacing enable tight PCB layouts.
• Versatile Ripple Performance: Specified ripple current at both 120 Hz and 100 kHz supports use across a range of switching and linear power circuits.
• Wide Temperature Range: −40°C to +105°C operation supports deployment in varied ambient conditions.
• Compliance: RoHS conformity aligns with regulatory requirements for lead‑restricted assemblies.
• Trusted Series Heritage: Part of Nichicon’s ULD long‑life series, designed for miniature long‑life aluminum electrolytic applications.
