UCZ1V142MNQ1MS

The UCZ1V142MNQ1MS is a Nichicon UCZ-series aluminum electrolytic chip capacitor in a surface-mount can package designed for high-reliability applications up to +125°C. It provides 1.4 mF capacitance at 35 V with low-temperature ESR characteristics and packaging suitable for automated assembly.

Targeted at systems that require high ripple handling, elevated operating temperature, and AEC‑Q200 qualification, this part is suited for demanding power and electronics assemblies where robust decoupling and energy storage are required.

Key Features

• Capacitance & Voltage — 1.4 mF (1400 μF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C, rated for 35 V operation.
• High Temperature Operation — Rated operating temperature range −40°C to +125°C and endurance specified at 3500 hours at 125°C.
• Low Temperature ESR — ESR specified at −40°C with a measured ESR of 45 mΩ at 20°C/100 kHz for improved AC performance.
• High Ripple Current Capability — Low-frequency ripple current of 1.3 A (120 Hz) and high-frequency ripple current of 2.6 A (10 kHz) to support power filtering and smoothing.
• Leakage Current — Typical leakage current listed at 490 μA after voltage application (20°C).
• Surface-Mount Packaging — φ18 × 16.5L can-style SMD with embossed carrier taping compatible with automated pick-and-place processes; recommended land size L:1.83 × W:1.83 cm.
• AEC‑Q200 Qualified — Designed for applications requiring AEC‑Q200 qualification and RoHS compliance.

Typical Applications

• Automotive Electronics — AEC‑Q200 qualification and +125°C endurance make this capacitor suitable for automotive control modules and power systems that require elevated temperature operation.
• High-Temperature Power Systems — Component-level rating to +125°C and 3500 h endurance at that temperature support use in high-heat environments.
• Automated Surface-Mount Assembly — Embossed carrier taping and chip-type SMD format streamline placement in high-volume manufacturing.

Unique Advantages

• High energy density in an SMD can — 1400 μF capacitance in a φ18 × 16.5L package provides substantial charge storage in a compact surface-mount form factor.
• Low ESR for better AC performance — 45 mΩ ESR at 100 kHz helps reduce dissipation and improves high-frequency filtering effectiveness.
• Designed for elevated-temperature reliability — Endurance rating of 3500 hours at 125°C supports long-term use in hot operating conditions.
• High ripple handling — 1.3 A (120 Hz) and 2.6 A (10 kHz) ripple currents accommodate demanding power smoothing and decoupling tasks.
• Automated assembly ready — Embossed carrier taping and recommended land pattern simplify pick-and-place integration and repeatable soldering.
• Standards and compliance — AEC‑Q200 qualification and RoHS compliance support regulated and reliability-focused designs.
