UKL1E471KHD

The UKL1E471KHD is a Nichicon UKL series miniature aluminum electrolytic capacitor in a radial‑lead can, rated at 470 µF and 25 V. It is part of Nichicon’s low‑leakage UKL family and is supplied in bulk or bag packing with 5 mm lead spacing.

Status: End Of Life. This unit is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Capacitance & Tolerance — 470 µF with tolerance of −10% to +10% at 120 Hz, 20 °C for stable bulk capacitance in power circuits.
• Rated Voltage — 25 V working voltage suitable for low‑voltage DC applications.
• Low Leakage — Low leakage construction with a specified leakage current of 23.5 µA, supporting applications where minimal self‑discharge is required.
• Loss Tangent (tan δ) — tan δ = 0.12 measured at 20 °C, 120 Hz, indicating controlled dissipation for the rated conditions.
• Ripple Handling — 660 mA ripple current at 120 Hz and 990 mA at 10 kHz, giving capability to handle AC ripple across a range of frequencies.
• Reliability / Endurance — Life rating of 2000 hours at 85 °C under rated voltage, providing defined endurance for elevated‑temperature operation.
• Operating Temperature — −40 °C to +85 °C, suitable for a broad ambient range common to consumer and electronics applications.
• Mechanical Package — Compact radial can, size φ12.5 × 20 mm (D × L) with 5.0 mm lead spacing (±0.5 mm) and standard radial lead mounting.
• Compliance — RoHS compliant.

Typical Applications

• Audio — Intended for use in audio-related circuitry as specified in the product data.
• Compact Radial‑Lead Designs — Fits φ12.5 × 20 mm footprints where a radial can capacitor is required.
• General Power Filtering — Bulk capacitance and ripple current ratings make it suitable for filtering and smoothing in low‑voltage DC circuits.

Unique Advantages

• Low Leakage Construction: The specified low leakage current (23.5 µA) reduces self‑discharge and helps maintain DC bias over time.
• Frequency Versatility: Rated ripple currents at both 120 Hz and 10 kHz (660 mA and 990 mA respectively) accommodate low‑ and high‑frequency ripple environments.
• Compact Can Size: φ12.5 × 20 mm package enables higher capacitance in a small radial footprint for space‑constrained assemblies.
• Defined Endurance: 2000‑hour life at 85 °C under rated voltage provides a measurable reliability baseline for thermal stress planning.
• RoHS Compliant: Meets RoHS requirements for restricted substances, supporting regulatory needs for many product lines.
