UCN1E471MCL1GS

The UCN1E471MCL1GS is a surface‑mount aluminum electrolytic chip capacitor in the Nichicon UCN series designed for high‑reliability, high‑temperature applications. It provides 470 µF capacitance at 25 V in a compact φ8×10 mm can (chip type) with embossed carrier taping for automated assembly.

Engineered for demanding environments, this part combines a wide operating temperature range (−40 °C to 125 °C), AEC‑Q200 qualification, and long endurance (3000 hours at 125 °C), making it suitable for applications that require stable bulk capacitance and controlled loss over time.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with ±20% tolerance, rated for 25 V operation.
• High Temperature Endurance — Rated life of 3000 hours at 125 °C; after endurance test the capacitor meets specified limits for capacitance change, tan δ, and leakage current.
• Low Loss Characteristics — tan δ (DF) max 0.18 measured at 20 °C, 120 Hz, supporting reliable energy storage with controlled dissipation.
• Measured ESR — Equivalent series resistance of 300 mΩ at 20 °C/100 kHz, supporting effective ripple performance at higher frequencies.
• Ripple Current Capability — Rated ripple current of 135 mA at 120 Hz and 270 mA at 10 kHz, enabling use in filtering and decoupling across frequency ranges.
• Leakage Current — Specified leakage current 117.5 µA (per product data), with datasheet limits consistent with standard rated‑voltage conditioning methods.
• Automated Assembly Ready — Chip‑type can in embossed carrier taping format suitable for automatic mounting processes; surface‑mount package case φ8×10 mm with recommended land size L: 8.3 × W: 8.3 mm.
• Compliance — RoHS compliant and AEC‑Q200 qualified for applications requiring industry reliability standards.

Typical Applications

• Automotive Electronics — Bulk energy storage and decoupling in control modules and electronics where AEC‑Q200 qualification and extended high‑temperature operation are required.
• Power Supply Filtering — Bulk smoothing and ripple suppression in DC‑DC converters and power rails, leveraging the part’s ripple current ratings and measured ESR.
• Automated Surface‑Mount Production — Designed for pick‑and‑place with embossed carrier taping to streamline high‑volume PCB assembly.

Unique Advantages

• High‑temperature reliability: 3000 hours endurance at 125 °C delivers predictable lifetime performance for elevated ambient designs.
• AEC‑Q200 qualification: Supports designs that require supplier assurance for components used in demanding or safety‑critical systems.
• Frequency‑aware ripple performance: Specified ripple current values at both 120 Hz and 10 kHz plus 300 mΩ ESR at 100 kHz enable effective noise suppression across low and high frequencies.
• Assembly efficiency: Embossed carrier taping and chip‑type SMD can form factor simplify placement and reduce handling time on automated lines.
• Compact footprint: φ8×10 mm package with defined land pattern (8.3 × 8.3 mm) provides a high capacitance density for space‑constrained boards.
