UCZ1V122MNQ1MS

The UCZ1V122MNQ1MS is a surface‑mount aluminum electrolytic capacitor in Nichicon’s UCZ series designed for high‑temperature, high‑reliability applications. It delivers 1200 µF capacitance at a 35 V rating in a compact chip can package suitable for automated placement and embossed carrier taping.

Targeted use cases include power filtering, bulk energy smoothing and decoupling in systems that require wide operating temperature and long endurance. Key value propositions are a wide −40 °C to +125 °C operating range, AEC‑Q200 qualification, and specifications tuned for low ESR and high ripple handling.

Key Features

• Electrical Performance — 1200 µF nominal capacitance with ±20% tolerance and 35 V rated voltage; specified tan δ (DF) of 0.16 measured at 20 °C, 120 Hz.
• Low ESR and High Ripple Handling — ESR of 45 mΩ at 20 °C / 100 kHz and ripple current ratings of 1.3 A at 120 Hz (low frequency) and 2.6 A at 100 kHz (high frequency) to support power conversion and decoupling tasks.
• Thermal and Endurance — Rated for continuous operation from −40 °C to +125 °C with an endurance rating of 3500 hours at 125 °C.
• Reliability & Qualification — AEC‑Q200 qualified and RoHS compliant for use in demanding environments where qualification matters.
• Package & Mounting — Chip‑type radial can SMD package, size φ18 × 16.5L (1.8 × 1.65 cm), designed for automated placement and supplied in embossed carrier taping.
• Leakage Current — Specified leakage current of 420 µA, measured under rated conditions.

Typical Applications

• Automotive Electronics — Energy storage and smoothing in vehicle power systems where AEC‑Q200 qualification and wide temperature range are required.
• Power Conversion — Input/output filtering and bulk capacitance for DC–DC converters and power supplies that demand low ESR and high ripple capability.
• Industrial Controls — Bulk decoupling and transient suppression in controllers and servo drives operating across broad temperature ranges.
• Embedded Systems — Local energy reservoir and decoupling for microcontroller and power management circuits in compact SMD form factors.

Unique Advantages

• High ripple tolerance: 1.3 A (120 Hz) and 2.6 A (100 kHz) ripple ratings reduce thermal stress and support higher power density designs.
• Low high‑frequency ESR: 45 mΩ at 100 kHz enables improved smoothing performance in switching applications and better transient response.
• Wide temperature operation: −40 °C to +125 °C rating allows deployment in harsh thermal environments without derating system performance.
• Long endurance at elevated temperature: 3500 hours at 125 °C supports longevity in continuous‑duty applications.
• Automotive‑grade qualification: AEC‑Q200 status provides confidence for designs targeting automotive and other reliability‑sensitive markets.
• SMD, tape‑fed packaging: Embossed carrier taping and compact φ18 × 16.5L can format simplify high‑volume, automated assembly.
