UCZ1H561MNQ1MS

The UCZ1H561MNQ1MS is a Nichicon UCZ‑series chip‑type aluminum electrolytic capacitor specified for continuous operation up to +125°C. It combines a 560 µF nominal capacitance with a 50 V rated voltage in a surface‑mount can package designed for automated placement.

Targeted at applications that require high temperature endurance and industry qualification, this part delivers specified low‑temperature ESR behavior, defined ripple current handling, and AEC‑Q200 qualification for demanding environments.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with a 50 V rated voltage and capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Temperature Range & Endurance — Rated for operation from −40°C to +125°C with a lifetime of 3500 hours at 125°C.
• Low‑temperature ESR Specification — ESR specified as 80 mΩ at 100 kHz and an added ESR requirement after the −40°C test to ensure performance across the temperature range.
• Ripple Current Performance — Rated ripple current of 1 A at 120 Hz and 2 A at 10 kHz to support power filtering and decoupling duties.
• Surface‑mount Can Package — Radial, SMD can package (L: 1.65 × D: 1.6 cm) designed for automatic mounting machines fed by carrier tape; recommended surface mount land size L: 1.63 × W: 1.63 cm.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS‑compliant (2011/65/EU, (EU)2015/863), with leakage current specified as ≤0.01CV (µA) after 2 minutes at 20°C.

Typical Applications

• Automotive electronics — Suitable for on‑board power filtering and energy storage where AEC‑Q200 qualification and +125°C operation are required.
• High‑temperature power modules — Used for smoothing and decoupling in assemblies exposed to elevated ambient temperatures up to +125°C.
• Automated surface‑mount production — Designed for placement with carrier‑tape fed automatic mounting machines and compatible with standard SMD assembly flows.

Unique Advantages

• Defined high‑temperature endurance — 3500 hours at 125°C provides a measurable reliability metric for designs deployed in thermally demanding environments.
• Low‑temperature performance assurance — ESR is specified after the −40°C test, delivering verified behavior across the full −40°C to +125°C range.
• Measurable ripple handling — Dual ripple current ratings (1 A at 120 Hz, 2 A at 10 kHz) make it straightforward to assess suitability for specific filtering and decoupling requirements.
• Industry qualification — AEC‑Q200 qualification and RoHS compliance help meet regulated and reliability‑conscious program requirements.
• Manufacturing ready — SMD can package sized at 1.65 × 1.6 cm and carrier‑tape compatibility support efficient, automated PCB assembly.
