UCN1E181MCL1GS

The UCN1E181MCL1GS is a chip-style aluminum electrolytic capacitor from Nichicon's UCN series, designed for surface-mount applications requiring long life and low equivalent series resistance. This polarized SMD can delivers 180 µF at a 25 V rating with RoHS compliance and AEC-Q200 qualification for demanding environments.

Engineered for high-temperature operation and sustained performance, the device targets automotive and other systems where elevated temperature endurance, compact footprint, and reliable filtering are required.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance at a rated voltage of 25 V with a tolerance of ±20%.
• Low ESR — ESR of 500 mΩ measured at 100 kHz to support effective ripple suppression in power rails.
• High temperature and long life — Rated for operation from −40°C to 125°C with a guaranteed lifetime of 3000 hours at 125°C.
• Ripple current capability — Specified ripple ratings of 98.5 mA at 120 Hz and 197 mA at 10 kHz for reliable AC performance.
• Surface-mount chip package — Radial, can-type SMD package sized L: 7.7 × D: 6.3 mm with compatible land size L: 6.6 × W: 6.6 mm for automated placement.
• Reliability and standards — AEC-Q200 qualified and RoHS compliant for use in regulated applications.
• Endurance characteristics — After 3000 hours at 125°C under rated voltage, specified limits apply: capacitance change within ±30%, tan δ within 300% of initial, and leakage current at or below initial specified value.

Typical Applications

• Automotive electronics — Filtering and decoupling in automotive control modules where AEC-Q200 qualification and high-temperature endurance are required.
• Power supply smoothing — Bulk or local smoothing on DC rails in compact SMD power designs benefiting from low ESR and defined ripple current ratings.
• Harsh-environment electronics — Electronic assemblies operating between −40°C and 125°C that demand long life and stable capacitance over time.

Unique Advantages

• AEC-Q200 Qualification: Provides confidence for use in regulated automotive and similarly demanding applications.
• Low ESR performance: 500 mΩ at 100 kHz helps reduce power loss and improve ripple attenuation in compact power networks.
• High-temperature durability: Rated operation to 125°C and a 3000-hour life rating at that temperature support sustained performance in elevated-temperature systems.
• SMD chip form factor: Radial can SMD package and specified land pattern enable automated assembly and compact board layouts.
• Measured ripple specifications: Provided ripple current values at 120 Hz and 10 kHz allow designers to evaluate AC stress for intended applications.
• Regulatory compliance: RoHS conformity for use in environments requiring restricted substance compliance.
