UCX1V561MNQ1MS

The UCX1V561MNQ1MS is a chip-type aluminum electrolytic capacitor designed for high-reliability applications requiring elevated temperature endurance and low equivalent series resistance. As a surface-mount, polarized capacitor with AEC‑Q200 qualification and RoHS compliance, it targets demanding electronic power systems where sustained performance at up to +135°C is required.

With a rated capacitance of 560 µF at 35 V and engineered low-temperature ESR specification, this part is optimized for bulk decoupling and ripple handling in compact, automated assembly workflows using embossed carrier taping.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with ±20% tolerance at 120 Hz, rated for 35 V operation.
• High Temperature Endurance — Rated for continuous operation to +135°C with endurance specified at 2000 hours at 135°C under rated voltage.
• Low ESR — ESR of 70 mΩ measured at 20°C, 100 kHz, supporting lower dissipation and improved ripple handling.
• High Ripple Current Capability — Low-frequency ripple current 375 mA (120 Hz) and high-frequency ripple current 750 mA (10 kHz) for robust power-rail smoothing.
• Leakage and Loss Characteristics — Part-specific leakage current 196 µA; tan δ and impedance characteristics conform to series specifications for stable performance across temperature.
• Package & Mounting — Chip-type radial can SMD in a φ12.5 × 13.5 mm package (L: 13.5 mm, D: 12.5 mm) suitable for automatic placement; supplied in embossed carrier taping for high-volume assembly.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant for regulated environments and high-reliability programs.

Typical Applications

• Automotive electronics — AEC‑Q200 qualification and +135°C endurance make the UCX1V561MNQ1MS appropriate for automotive power modules and electronic control units that require high-temperature stability.
• Power management and DC–DC converters — 560 µF at 35 V combined with low ESR and elevated ripple current ratings supports bulk decoupling and smoothing on intermediate power rails.
• Industrial and embedded systems — The high temperature range and long endurance make this capacitor suitable for compact, high-reliability assemblies used in industrial control and instrumentation.

Unique Advantages

• Designed for high-temperature operation: Endurance specified for 2000 hours at 135°C provides predictable aging and performance in hot environments.
• Low ESR for lower losses: 70 mΩ ESR at 100 kHz reduces heat build-up and improves energy efficiency in power rails.
• Strong ripple handling: Defined low- and high-frequency ripple currents (375 mA @120 Hz, 750 mA @10 kHz) enable reliable filtering across a range of operating frequencies.
• SMT-ready packaging: Chip-type radial can format and embossed carrier taping support automated surface-mount assembly and higher throughput.
• Industry reliability qualification: AEC‑Q200 qualification and RoHS compliance signal suitability for regulated, reliability-focused development cycles.
