UVK2G470MHD

The UVK2G470MHD is an aluminum electrolytic capacitor in a radial-lead can optimized for general-purpose electronic designs that require 47 µF at a 400 V rating. It pairs compact dimensions (φ16 × 25 mm) and radial mounting with electrical characteristics aimed at high-voltage smoothing, decoupling and energy-storage tasks in general-purpose circuits.

Designed and manufactured by Nichicon and offered in mass-production, the UVK2G470MHD delivers a combination of high-voltage capability, measurable ripple handling and defined endurance for applications requiring stable performance up to 85°C.

Key Features

• Electrical parameters: 47 µF nominal capacitance with tolerance ±20% (−20% to +20%), rated for 400 V operation; tangent of loss angle (tan δ) 0.25 at 20°C, 120 Hz.
• Ripple handling: Low-frequency ripple current 280 mA at 120 Hz and high-frequency ripple current 448 mA at 10 kHz, enabling effective smoothing under varying ripple conditions.
• Leakage current: Specified leakage current of 852 µA for controlled standby and low-loss performance after voltage application.
• Reliability & endurance: Rated endurance of 2000 hours at 85°C with specified limits for capacitance change, tan δ and leakage current after test.
• Operating range: Specified operating temperature from −40°C to +85°C to support a wide range of environmental conditions for general-purpose equipment.
• Compact radial package: Radial-lead, can-style package with diameter φ16 mm and length 25 mm, lead spacing 7.5 mm; available in bulk (no terminal forming) or bag packing.
• RoHS compliance: Series-level compliance to the RoHS directive is specified in the product series documentation.
• Production status: Available in mass production from Nichicon.

Typical Applications

• General-purpose power filtering: 47 µF at 400 V provides smoothing and decoupling capability for general-purpose power rails and high-voltage rails in electronic designs.
• DC bus decoupling: The 400 V rating and measurable ripple current specifications make this part suitable for decoupling high-voltage DC bus sections in power modules and converters.
• Energy storage for high-voltage circuits: Compact can-style radial format offers localized energy storage where space is constrained but high-voltage capability is required.

Unique Advantages

• High-voltage capability: 400 V rated voltage enables use in higher-voltage circuits without needing larger form-factor parts.
• Compact footprint: φ16 × 25 mm can size offers a smaller physical profile while maintaining 47 µF capacitance, reducing board area compared to larger cans.
• Measured ripple performance: Defined low- and high-frequency ripple current ratings (280 mA @120 Hz, 448 mA @10 kHz) provide clear expectations for filtering performance across frequencies.
• Specified endurance: 2000 hours at 85°C gives a quantifiable reliability metric for design lifetime planning and thermal stress considerations.
• Controlled leakage: Leakage current specified at 852 µA for predictable standby and low-loss behavior after voltage application.
• RoHS-aligned series: Series documentation indicates compliance with RoHS directives for regulatory alignment in applicable regions.
