ULD2D2R2MED

The ULD2D2R2MED is a Nichicon ULD-series radial lead aluminum electrolytic capacitor offering 2.2 µF capacitance at a 200 V rated voltage in a compact can-style package. It is part of the ULD family of miniature, long-life capacitors and is suited for general-purpose power-supply applications including LED lighting power supplies.

Designed for board-level use where a small footprint, high working voltage and reliable operation across a wide temperature range are required, this radial-lead capacitor delivers defined electrical characteristics and long endurance for sustained thermal and electrical loading.

Key Features

• Electrical Characteristics — 2.2 µF nominal capacitance with tolerance ±20% (–20% to +20%); rated for 200 V DC.
• Loss and Leakage — Tangent of loss angle (tanδ) 0.24 measured at 20°C, 120 Hz; specified leakage current 84 µA.
• Ripple Handling — Low-frequency ripple current 36 mA at 120 Hz and high-frequency ripple current 72 mA at 100 kHz, supporting both mains-frequency and switch-mode environments.
• Reliability and Lifetime — Endurance specified as 12,000 hours at 105°C; rated operating temperature range –40°C to +105°C.
• Package and Mounting — Radial lead (can) construction, size φ6.3 × 11 mm, lead spacing 2.5 mm (lead-spacing tolerance ±0.5 mm); supplied in bulk (no terminal forming) or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• LED Lighting Power Supplies — Suited for DC link and smoothing duties in LED drivers where a compact, long-life high-voltage capacitor is needed.
• General Purpose Power Filtering — Decoupling and smoothing in compact power-supply circuits up to 200 V.
• Compact Power Modules — Board-level use where small can size and radial leads facilitate simple mounting and assembly workflows.

Unique Advantages

• 200 V Rated Voltage — Supports mid- to high-voltage DC circuits without upsizing the capacitor.
• Compact Footprint — φ6.3 × 11 mm can size reduces PCB area compared with larger radial electrolytics.
• Defined Ripple Performance — Specified ripple currents at both 120 Hz and 100 kHz give predictable thermal loading for design margining.
• Extended High-Temperature Endurance — 12,000 hours at 105°C provides a clear reliability target for thermal-stressed designs.
• Radial-Lead Convenience — Through-hole radial leads simplify prototyping and repair, and are compatible with a variety of assembly processes.
• RoHS Compliance — Meets regulatory requirements for lead-restricted applications.
