UVK2D4R7MED

The UVK2D4R7MED is a miniature aluminum electrolytic capacitor in a radial-lead can designed for general-purpose electronic circuits. It provides 4.7 µF capacitance at a 200 V rating with polarized radial leads for through-hole mounting and compact, space-conscious layouts.

Key electrical and reliability characteristics include a temperature range of −40°C to +85°C, a rated endurance of 2000 hours at 85°C, and RoHS compliance as specified for the UVK series. Product status: End Of Life.

Key Features

• Capacitance & Voltage — 4.7 µF rated capacitance with a 200 V working voltage and ±20% tolerance for predictable performance in power and signal circuits.
• Electrical Loss & Leakage — Tangent of loss angle (tanδ) 0.2 measured at 20°C, 120 Hz and specified leakage current of 134 µA for this part number.
• Ripple Handling — Specified low-frequency ripple current of 50 mA at 120 Hz and high-frequency ripple current of 80 mA at 10 kHz for common decoupling and smoothing tasks.
• Reliability & Lifetime — Endurance rating of 2000 hours at 85°C with limits on capacitance change, tanδ increase and leakage current as defined by the UVK series endurance specifications.
• Package & Mounting — Radial lead, polarized aluminum can with size φ6.3 × 11 mm, lead spacing 2.5 mm (±0.5 mm), and available in bulk or bag packing (no terminal forming).
• Operating Range — Rated to operate from −40°C to +85°C as part of the UVK category temperature range.
• Series Attributes — Part of Nichicon’s UVK miniature-sized series, noted as one rank smaller case sizes than the UVR series and compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronics — Intended for general-purpose circuit use where a polarized 4.7 µF, 200 V capacitor is required.
• Space-constrained designs — Miniature φ6.3 × 11 mm radial can and small lead spacing make the part suitable for compact through-hole PCBs and tight component layouts.
• High-voltage decoupling — 200 V rating supports decoupling and smoothing in mid-to-high-voltage power rails within the specified temperature and ripple limits.
• Moderate-temperature applications — Rated operation from −40°C to +85°C with 2000-hour life at 85°C for applications requiring defined endurance at elevated ambient temperatures.

Unique Advantages

• Compact footprint: Miniature case (φ6.3 × 11 mm) reduces PCB area while preserving 200 V capability for space-sensitive designs.
• Defined endurance: 2000 hours at 85°C provides a clear lifetime expectation for thermal stress planning and design margining.
• Measured electrical parameters: Specified tanδ and leakage current values (tanδ 0.2; leakage 134 µA) allow predictable budgeting of losses and leakage in design calculations.
• Radial-lead convenience: Through-hole radial package simplifies handling, assembly, and replacement in repairable or prototype-heavy applications.
• RoHS compliance (series): UVK series compliance with RoHS directives supports use in regulated markets where mandated.
• Packaging flexibility: Available in bulk (no terminal forming) or bag packing to match procurement and assembly preferences.
