UCX1V561MNS1MS

The UCX1V561MNS1MS is a chip‑type aluminum electrolytic capacitor from Nichicon's UCX series, designed for surface‑mount assembly and carrier‑tape automatic placement. It provides 560 µF capacitance at a 35 V rating with polarized construction suitable for power filtering and energy storage in elevated temperature environments.

Engineered for high‑temperature operation up to +135°C and AEC‑Q200 qualified, this part delivers controlled ESR after low‑temperature testing and defined ripple handling for demanding automotive and industrial power applications.

Key Features

• Capacitance & Voltage — 560 µF rated capacitance at 35 V with tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High‑Temperature Endurance — Rated for operation from −40°C to +135°C with a specified lifetime of 2000 hours at 135°C; endurance criteria include capacitance change within ±30%, tan δ ≤ 300% of initial specified value, and leakage current within initial limits after the test.
• Low‑Temperature ESR Specification — ESR specification added after the −40°C test; measured equivalent series resistance of 70 mΩ at 100 kHz.
• Ripple Current Performance — Rated ripple currents of 375 mA at 120 Hz and 750 mA at 10 kHz for effective smoothing in power stages.
• Surface‑Mount, Tape‑Fed Packaging — Chip‑type radial can in an SMD package compatible with automatic mounting machines; surface mount land size is 12.8 mm × 12.8 mm and the part body measures 13.5 mm × 12.5 mm (L × D). The capacitor is polarized.
• Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant for regulated environments and high‑reliability designs.

Typical Applications

• Automotive electronic modules — Bulk filtering and decoupling in control units where AEC‑Q200 qualification and +135°C operation are required.
• Power conversion and DC–DC converters — Output smoothing and energy buffering that benefit from 560 µF capacitance and low ESR.
• Industrial high‑temperature power supplies — Filtering and transient energy storage in elevated ambient temperature environments up to 135°C.

Unique Advantages

• Designed for high ambient temperatures: Specified operation to +135°C with a 2000‑hour endurance rating at that temperature for predictable long‑term performance.
• Validated low‑temperature ESR behavior: ESR specification confirmed after −40°C testing and an explicit ESR value (70 mΩ at 100 kHz) for reliable AC performance across temperature extremes.
• Effective ripple handling: Defined ripple current ratings at both 120 Hz and 10 kHz help ensure adequate thermal and electrical performance in power stages.
• Surface‑mount, tape‑feed ready: Chip‑type SMD package simplifies automated assembly and PCB placement for modern manufacturing flows.
• AEC‑Q200 and RoHS compliance: Qualification and environmental compliance support use in regulated automotive and industrial programs.
