UVK2GR47MED

The UVK2GR47MED from Nichicon is a radial-lead aluminum electrolytic capacitor in the UVK series designed for general-purpose high-voltage applications. It combines a compact radial-can package (φ6.3 × 11 mm) with a 4.7 µF capacitance and a 450 V rating to support high-voltage decoupling and filtering in space-constrained assemblies.

Key value comes from its defined耐 voltage, compact footprint, and application-oriented specifications such as low leakage, specified ripple currents, and a 2000-hour endurance at 85°C — useful for designers who need verifiable performance parameters for power and control circuits.

Key Features

• Rated Capacitance and Tolerance – 4.7 µF with ±20% tolerance (measured at 120 Hz, 20°C), providing predictable bulk capacitance for decoupling and smoothing.
• High Voltage Capability – 450 V rated voltage suitable for high-voltage DC applications where compact high-voltage capacitance is required.
• Compact Radial Can Package – φ6.3 × 11 mm radial-lead can with 2.5 mm lead spacing (±0.5 mm) for tight PCB layouts and through-hole assembly.
• Ripple Current Ratings – Low-frequency ripple current 12 mA (120 Hz) and high-frequency ripple current 19.2 mA (10 kHz), enabling defined performance under AC ripple conditions.
• Low Leakage – Specified leakage current of 58.8 µA after rated voltage application, aiding in predictable standby and bias behavior.
• Endurance and Temperature Range – 2000 hours at 85°C endurance and an operating temperature range of −40°C to +85°C for stable performance over the stated life test.
• Polarized, General-Purpose Fit – Polarized aluminum electrolytic designed for general-purpose electrical and electronic applications.
• RoHS Compliant & Packaging Options – RoHS-compliant materials; available in bulk (no terminal forming) or bag packing.

Typical Applications

• Power Supply Filtering – Bulk decoupling and smoothing on high-voltage DC rails where a compact 4.7 µF, 450 V capacitor is required.
• High-Voltage DC Link Decoupling – Local energy storage and ripple attenuation on DC link or intermediate circuits in power conversion modules.
• Industrial Control Electronics – Filtering and energy conditioning in compact control and instrumentation modules operating up to 85°C.
• Instrumentation and Measurement – Use in measurement front-ends or test equipment where predictable leakage and low-frequency ripple performance are important.

Unique Advantages

• Compact high-voltage solution: 450 V rating in a φ6.3 × 11 mm radial can enables space-efficient placement of high-voltage capacitance.
• Defined ripple and leakage specs: Published ripple currents and leakage current provide designers with measurable parameters for thermal and bias budgeting.
• Endurance data provided: 2000 hours at 85°C gives an explicit lifecycle reference for reliability planning and qualification testing.
• Standardized radial footprint: 2.5 mm lead spacing (±0.5 mm) and common radial-can form factor simplify PCB layout and assembly processes.
• RoHS compliance and packaging options: Environmentally compliant materials and bulk/bag packing choices support production and inventory handling needs.
