ULD2E2R2MED

The ULD2E2R2MED is an aluminum electrolytic capacitor from Nichicon's ULD series, presented in a miniature radial-lead can. It delivers 2.2 µF nominal capacitance with a 250 V rating in a compact φ6.3 × 11 mm package with 2.5 mm lead spacing.

Designed for general-purpose electronic use and suited for power-supply applications including LED lighting, this part combines a wide operating temperature range (−40°C to +105°C) with defined endurance and electrical characteristics such as low-frequency and high-frequency ripple-current ratings and controlled leakage and loss-angle values.

Key Features

• Capacitance & Voltage — 2.2 µF nominal capacitance with a tolerance of −20% to +20% and a rated voltage of 250 V.
• Temperature & Endurance — Rated operating temperature from −40°C to +105°C with a life/endurance specification of 12,000 hours at 105°C.
• Loss Angle (tan δ) — tanδ = 0.24 measured at 20°C, 120 Hz, providing a specified dissipation characteristic for design calculations.
• Ripple Current & Leakage — Low-frequency ripple current 36 mA at 120 Hz, high-frequency ripple current 72 mA at 100 kHz, and leakage current specified at 95 µA.
• Package & Mounting — Radial lead can form factor, dimensions φ6.3 × 11 mm, lead spacing 2.5 mm with ±0.5 mm tolerance; suitable for through-hole mounting.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to support different production workflows.
• Compliance & Status — RoHS compliant; product status: End Of Life.

Typical Applications

• LED lighting power supplies — The ULD series is indicated as suited for power-supply use in LED lighting; this part provides compact, high-voltage capacitance for those circuits.
• General-purpose electronics — For designers specifying a 250 V radial-lead electrolytic capacitor in compact assemblies where a defined life and temperature range are required.
• Compact 250 V-rated circuits — Small footprint φ6.3 × 11 mm can accommodates board-area-constrained designs that require 2.2 µF at 250 V.

Unique Advantages

• Compact, high-voltage capability — Provides 2.2 µF at 250 V in a φ6.3 × 11 mm radial can to save board space in high-voltage designs.
• Defined long-term endurance — 12,000-hour rated life at 105°C supports sustained operation in elevated-temperature environments.
• Measured electrical parameters — Specified tanδ (0.24), leakage current (95 µA), and ripple-current ratings (36 mA @120 Hz, 72 mA @100 kHz) allow predictable performance in filter and supply roles.
• Through-hole mounting simplicity — Radial lead form and standard lead spacing (2.5 mm ±0.5 mm) simplify PCB layout and assembly for legacy and mixed-technology boards.
• RoHS compliant — Meets RoHS directive requirements for restricted substances.
