UCL1E151MNL1GS

The UCL1E151MNL1GS is a chip‑type, low‑impedance aluminum electrolytic capacitor from Nichicon’s UCL series, specified for surface‑mount applications. It delivers 150 µF capacitance at a 25 V rating in a compact φ8 × 10 mm SMD can package.

Designed for applications that require high ripple handling and robust thermal endurance, this part offers measurable low impedance, extended high‑temperature life, and an AEC‑Q200 rating for automotive applications.

Key Features

• Capacitance & Voltage — 150 µF capacitance rated at 25 V with a tolerance of −20% to +20% for predictable energy storage.
• Low Impedance — Measured impedance of 80 mΩ supports effective decoupling and filtering on power rails.
• Ripple Current Performance — Low‑frequency ripple current of 425 mA at 120 Hz and high‑frequency ripple current of 850 mA at 10 kHz to support both bulk and high‑frequency filtering.
• Loss Characteristics — tanδ (DF) = 0.14 measured at 20°C, 120 Hz, enabling clear expectations for dissipation in AC conditions.
• Leakage Current — Specified leakage current of 37.5 µA (measured after rated voltage application), suitable for power‑sensitive circuits.
• Thermal & Endurance — Operating temperature range −55°C to +105°C with life endurance of 2000 hours at 105°C; endurance spec includes capacitance change within ±30% and tanδ within 200% of initial specified value after the endurance test.
• Package & Mounting — Radial can SMD (chip type) with package dimensions φ8 × 10 mm and recommended land size 8.3 × 8.3 mm for embossed carrier taping.
• Qualification — AEC‑Q200 rated for automotive applications, supporting designs requiring recognized component stress qualification.

Typical Applications

• Power rail decoupling — Low impedance and high ripple current ratings make this capacitor well suited for smoothing and stabilizing DC power rails.
• DC/DC converter input/output filtering — Compact SMD can package and high‑frequency ripple capability help reduce output ripple and improve converter stability.
• Automotive electronics — AEC‑Q200 rating, wide temperature range (−55°C to +105°C) and 2000 h endurance at 105°C support use in automotive control modules and infotainment power circuits.

Unique Advantages

• Measurable low impedance: 80 mΩ impedance gives designers a concrete performance metric for power delivery and transient suppression.
• High ripple capability across frequencies: Separate low‑ and high‑frequency ripple current specifications (425 mA @120 Hz, 850 mA @10 kHz) enable predictable performance in mixed‑frequency environments.
• High‑temperature endurance: 2000 hours at 105°C with defined post‑test limits on capacitance and dissipation factor supports long life in elevated ambient temperatures.
• Automotive qualification: AEC‑Q200 rating provides an industry‑recognized level of stress qualification for vehicle systems.
• Compact SMD can format: φ8 × 10 mm package and embossed carrier taping simplify board placement and automated assembly for space‑constrained designs.
