UVK2V470MHD

The UVK2V470MHD is a miniature aluminum electrolytic capacitor in Nichicon’s UVK series, supplied in a radial lead can. It provides 47 µF capacitance at a 350 V rated voltage with a polarized design and is intended for general-purpose electronic applications.

Designed for compact high-voltage circuits, this part combines a small φ16 × 25 mm footprint and 7.5 mm lead spacing with rated performance characteristics including specified ripple currents, leakage current, and a 2000-hour endurance at 85°C.

Key Features

• Capacitance and Voltage: 47 µF capacitance rated at 350 V, suitable for higher-voltage general-purpose circuitry.
• Miniature Radial Lead Package: φ16 × 25 mm can with 7.5 mm lead spacing in a radial lead configuration; available in bulk (no terminal forming) or bag packing.
• Temperature Range: Operates from −40°C to +85°C, supporting a wide ambient range for general-purpose equipment.
• Endurance: Qualified for 2000 hours at 85°C with capacitance change within ±20% and leakage current remaining at or below initial specified values after test.
• Ripple Current Ratings: Low-frequency ripple current 300 mA (120 Hz) and high-frequency ripple current 480 mA (10 kHz), supporting smoothing and filtering duties across frequency ranges.
• Leakage and Dissipation Factor: Specified leakage current of 758 µA and tan δ (DF) of 0.25 measured at 20°C, 120 Hz, enabling predictable loss and leakage behavior.
• RoHS Compliant: Built to meet RoHS requirements as noted for the UVK series.
• Compact Series Design: UVK series offers one rank smaller case sizes compared to UVR, enabling reduced board area for similar functions.

Typical Applications

• General-purpose power supplies: 47 µF at 350 V supports bulk smoothing and energy storage in higher-voltage supply rails where a compact radial solution is required.
• Power filtering and decoupling: Specified ripple current and dissipation factor make this capacitor suitable for filtering tasks across low and high frequency ranges.
• Electronic equipment requiring RoHS compliance: The UVK2V470MHD is RoHS compliant and appropriate for general-purpose electronic assemblies that require compliant components.

Unique Advantages

• High voltage capability: 350 V rating allows use in higher-voltage circuits while retaining a small package footprint.
• Compact footprint: φ16 × 25 mm can and radial lead termination reduce board space compared with larger electrolytic options in similar series.
• Frequency-flexible ripple handling: Separate low-frequency (300 mA at 120 Hz) and high-frequency (480 mA at 10 kHz) ripple specifications provide predictable performance across common ripple sources.
• Predictable leakage and loss: Specified leakage current (758 µA) and tan δ (0.25 at 20°C, 120 Hz) support reliable thermal and electrical design margins.
• Endurance-tested: 2000-hour life at 85°C with defined limits on capacitance, tan δ, and leakage current for long-term stability in endurance conditions.
• RoHS compliance: Meets RoHS directive requirements as indicated for the UVK series.
