UCL1E151MCL6GS

The UCL1E151MCL6GS is a chip-type, low-impedance surface-mount aluminum electrolytic capacitor from Nichicon's UCL series. It delivers 150 µF at 25 V in a compact φ10 × 7.7 mm can designed for automated placement and embossed carrier taping.

Engineered for applications that require robust ripple handling and wide operating temperature range, this capacitor combines AEC-Q200 qualification and RoHS compliance with a 2000-hour endurance rating at 105°C for demanding environments.

Key Features

• Capacitance & tolerance — 150 µF nominal capacitance with a tolerance of ±20% (measured at 120 Hz, 20°C), suitable for bulk decoupling and smoothing functions.
• Rated voltage — 25 V working voltage for a broad range of low-voltage power rails.
• Low impedance construction — Specified impedance of 100 mΩ and a tangent of loss angle (tan δ) of 0.14 (20°C, 120 Hz) to support stable performance under dynamic loads.
• Ripple current capability — 425 mA at 120 Hz (low frequency) and 850 mA at 10 kHz (high frequency) to handle AC ripple in power-supply applications.
• Leakage current — Leakage current specified at 37.5 µA after rated voltage application, enabling predictable standby behavior.
• High-temperature endurance — Rated for 2000 hours at 105°C, with specified limits on capacitance change, tan δ, and leakage after endurance testing.
• Temperature range — Operates from −55°C to +105°C for use across wide thermal conditions.
• Automotive-grade and environmental — AEC-Q200 qualified and stated RoHS compliance as part of the UCL series, supporting regulated production environments.
• Package & mounting — Chip-style radial can for surface-mount assembly; available in embossed carrier taping for automatic mounting.

Typical Applications

• Automotive electronic modules — Bulk decoupling and smoothing on low-voltage rails in control modules and body electronics where AEC-Q200 qualification is required.
• Power supply filtering — Local energy storage and ripple suppression on DC-DC converters and linear regulators thanks to high ripple current ratings.
• Industrial control equipment — Energy buffering and transient damping in control boards operating across −55°C to +105°C.
• Embedded systems — Stabilizing supply rails and providing hold-up in compact SMD form factors for automated assembly.

Unique Advantages

• Compact, high-capacitance SMD form — 150 µF in a φ10 × 7.7 mm package minimizes board area while delivering bulk capacitance for compact designs.
• Designed for automated assembly — Embossed carrier taping and chip-type package simplify pick-and-place integration and high-volume production.
• Robust ripple handling — Defined low- and high-frequency ripple current ratings reduce the need for oversized capacitors and improve power-stage stability.
• High-temperature endurance — 2000-hour rating at 105°C provides predictable long-term behavior in elevated-temperature environments.
• Qualification and compliance — AEC-Q200 qualification and series-level RoHS compliance support use in regulated, reliability-focused applications.
