ULD2E3R3MED

The ULD2E3R3MED is a Nichicon ULD series aluminum electrolytic capacitor in a miniature radial‑lead can. It provides 3.3 µF capacitance at a 250 V rating in a compact φ6.3 × 11 mm package with polarized radial leads.

Designed for general‑purpose power circuitry and compact power supplies — including LED lighting power supplies identified at the series level — this part offers a long‑life endurance specification, controlled dissipation, and RoHS compliance. Status: End Of Life.

Key Features

• Capacitance & Tolerance — 3.3 µF with tolerance −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 250 V working voltage suitable for higher‑voltage power applications.
• Low Loss — tanδ = 0.24 (measured at 20°C, 120 Hz, 250 V), helping maintain efficiency in AC/ripple conditions.
• Ripple Current Performance — 42 mA at 120 Hz (low frequency) and 84 mA at 100 kHz (high frequency) for ripple handling in both mains‑frequency and high‑frequency converter environments.
• Leakage Current — 122.5 µA (measured per product specification), supporting stable leakage behavior in DC circuits.
• Temperature & Endurance — Operating range −40°C to +105°C with a rated life of 12,000 hours at 105°C.
• Compact Radial Package — Can‑style radial package with dimensions φ6.3 × 11 mm and 2.5 mm lead spacing (±0.5 mm), ideal for through‑hole assembly.
• Mounting & Packaging — Polarized, radial‑lead mounting; supplied in bulk (no terminal forming) or bag packing.
• Regulatory — RoHS compliant.
• Lifecycle Status — End Of Life (EOL) — please confirm stock and lead times when requesting availability.

Typical Applications

• LED Lighting Power Supplies — Series‑level suitability for LED power applications; the ULD2E3R3MED provides compact, high‑voltage capacitance for smoothing and energy storage.
• Compact Power Supplies and DC–DC Converters — 250 V rating and defined ripple current specs support filtering and decoupling in space‑constrained, higher‑voltage designs.
• General‑Purpose Power Filtering — Polarized radial mounting and modest footprint make this part useful for general filtering and decoupling tasks on through‑hole assemblies.

Unique Advantages

• High working voltage in a miniature can: 250 V rating in a φ6.3 × 11 mm package gives designers high‑voltage capacitance without a large board impact.
• Defined ripple handling across frequencies: Specified ripple currents at 120 Hz and 100 kHz provide predictable performance for both mains‑frequency smoothing and high‑frequency converter environments.
• Long life at elevated temperature: Rated for 12,000 hours at 105°C, enabling longer service intervals in thermal stress conditions.
• Controlled dissipation: Specified tanδ (0.24 at 20°C, 120 Hz) supports low loss in AC and ripple applications where dissipation matters.
• Through‑hole, compact mounting: Radial lead and 2.5 mm lead spacing make the part straightforward to place in traditional PCB layouts and prototyping jigs.
• RoHS compliance and common packaging options: RoHS‑compliant construction and availability in bulk or bag packing simplify procurement and assembly planning.

Why Choose ULD2E3R3MED?

ULD2E3R3MED targets designers who need a compact, polarized aluminum electrolytic capacitor with a 250 V rating and clearly defined ripple, leakage, and loss characteristics. Its small can size (φ6.3 × 11 mm), radial leads, and 12,000‑hour endurance at 105°C make it suitable for space‑limited power assemblies where thermal endurance and predictable electrical behavior are required.

This part is appropriate for engineers specifying general‑purpose power filtering and smoothing in higher‑voltage circuits and for teams managing RoHS‑compliant BOMs. Confirm current availability and lifecycle considerations given the End Of Life status when planning production or maintenance inventories.
