UVK2E4R7MED

The UVK2E4R7MED is a miniature aluminum electrolytic capacitor in Nichicon’s UVK series, supplied in a radial lead can. It provides 4.7 µF capacitance at a 250 V rating with a compact φ6.3 × 11 mm footprint and 2.5 mm lead spacing, designed for general-purpose electronic applications that require a polarized through-hole capacitor.

As part of the UVK family (miniature sized), this component offers measurable electrical performance and endurance characteristics specified for operation from –40 °C to +85 °C and a rated endurance of 2000 hours at 85 °C.

Key Features

• Electrical Performance  4.7 µF capacitance with a tolerance of –20% to +20% and rated voltage of 250 V; tangent of loss angle (tan δ) specified at 0.2 measured at 20 °C, 120 Hz.
• Ripple Handling  Low-frequency ripple current rated at 50 mA (120 Hz) and high-frequency ripple current rated at 80 mA (10 kHz), supporting smoothing and filtering in general-purpose circuits.
• Leakage Current  Specified leakage current of 147 µA after application of rated voltage under standard test conditions.
• Reliability & Endurance  Endurance specified as 2000 hours at 85 °C with limits: capacitance change within ±20%, tan δ ≤ 200% of initial spec, and leakage current ≤ initial specified value after the test.
• Operating Range  Temperature range from –40 °C to +85 °C, suitable for a wide range of ambient conditions covered by the UVK series specifications.
• Mechanical & Packaging  Compact radial can: φ6.3 × 11 mm (L: 1.1 × D: 0.63 cm), lead spacing 2.5 mm with 0.5 mm tolerance; available in bulk (no terminal forming) or bag packing.
• Series and Compliance  Part of Nichicon’s UVK miniature series, noted for one-rank smaller case sizes than UVR; the UVK series is stated as compliant to the RoHS directive (2011/65/EU, (EU)2015/863) in the series documentation.
• Product Status  Status: End Of Life (EOL).

Typical Applications

• General-purpose circuitry  For designs requiring a polarized radial electrolytic capacitor with 4.7 µF at 250 V for filtering or energy storage in general-purpose electronic equipment.
• Through-hole board assemblies  Radial lead form factor and 2.5 mm lead spacing suit traditional through-hole mounting and prototyping workflows.
• Temperature-constrained environments  Use where operation within –40 °C to +85 °C and established endurance at 85 °C (2000 h) is acceptable.

Unique Advantages

• Compact footprint: The φ6.3 × 11 mm can minimizes board area while delivering 4.7 µF at 250 V, helping reduce component size in space-constrained designs.
• Clear electrical specifications: Specified tan δ, leakage current, and ripple current figures provided for predictable behavior in filter and smoothing roles.
• Endurance assurance: 2000 hours at 85 °C endurance characterization lets designers evaluate long-term performance against project requirements.
• Through-hole mounting: Radial lead construction with defined lead spacing simplifies placement for manual assembly and through-hole manufacturing processes.
• Series consistency: Part of the UVK series with documented RoHS compliance and miniature sizing information to aid component selection and form-factor planning.
