UHE1E470MDD

The UHE1E470MDD is a polarized aluminum electrolytic capacitor in a radial-lead can, offering 47 µF capacitance at a 25 V rating. It is a compact, general-purpose component with a φ5 × 11 mm package (L: 1.1 × D: 0.5 cm) and 2.0 mm lead spacing designed for through-hole radial mounting.

Rated for operation from −40°C to 105°C and specified with a 5,000-hour endurance at 105°C, this part is part of Nichicon’s UHE family, which emphasizes low impedance and high reliability. Status: End Of Life.

Key Features

• Capacitance & Tolerance — 47 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C for consistent bulk energy storage in general-purpose circuits.
• Voltage Rating — Rated at 25 V DC, suitable for stabilized low-voltage applications requiring polarized electrolytic capacitance.
• Electrical Loss and Leakage — Tangent of loss angle (tan δ) specified at 0.14 (20°C, 120 Hz) and leakage current measured at 11.75 µA, providing predictable dissipation and leakage behavior.
• Ripple Performance — Low-frequency ripple current of 147 mA (120 Hz) and high-frequency ripple current of 210 mA (10 kHz) to support filtering and smoothing tasks across common ripple spectra.
• Thermal and Endurance — Operating temperature range from −40°C to 105°C with a rated endurance of 5,000 hours at 105°C for long-term stability in elevated-temperature environments.
• Package & Mounting — Radial lead can (φ5 × 11 mm) with 2 mm lead spacing and bulk or bag packing options for through-hole assembly and prototyping workflows.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose electronics — Suitable where a polarized radial-lead aluminum electrolytic capacitor is required for energy storage and decoupling in general-purpose circuit designs.
• Space-constrained through-hole designs — Compact φ5 × 11 mm can and 2.0 mm lead spacing make it appropriate for tight board layouts that require through-hole components.
• Higher-temperature deployments — Rated operation to 105°C with a specified 5,000-hour endurance at that temperature for use in circuits exposed to elevated ambient conditions.

Unique Advantages

• Compact radial-lead form factor — φ5 × 11 mm package delivers 47 µF capacitance in a small through-hole footprint, simplifying placement in constrained designs.
• Measured ripple capability — Specified ripple currents at both low (120 Hz) and high (10 kHz) frequencies give clear guidance for filtering and smoothing design margins.
• Predictable electrical characteristics — Documented tan δ (0.14) and measured leakage current (11.75 µA) enable reliable selection and modeling in power and analog circuits.
• Wide operating temperature range — −40°C to 105°C rating supports deployment across a broad range of environmental conditions.
• RoHS compliant — Meets RoHS directive requirements for environmental regulatory needs.
