UCZ1E332MNQ1MS

The UCZ1E332MNQ1MS is a Nichicon UCZ-series surface-mount aluminum electrolytic capacitor engineered for high-temperature, high-reliability power applications. It delivers 3300 µF of capacitance in a compact SMD can (φ18 × 21.5L) with design attributes tuned for automated placement.

Key performance characteristics include a 25 V rating, broad operating range from -40°C to 125°C, low equivalent series resistance (32 mΩ at 100 kHz), and robust ripple handling—features that support demanding power-rail smoothing and bulk-energy storage requirements in automotive and industrial systems.

Key Features

• Form factor & mounting: Surface-mount radial can (Chip type) in a φ18 × 21.5L package with embossed carrier taping for automated placement; specified surface-mount land size is 1.83 × 1.83 cm.
• Capacitance & voltage: 3300 µF (±20%) rated at 25 V, providing substantial bulk capacitance for compact power designs.
• Temperature range & endurance: Rated for -40°C to +125°C with an endurance rating of 4000 hours at 125°C, supporting long-term operation in high-temperature environments.
• Low ESR & frequency performance: ESR of 32 mΩ measured at 20°C/100 kHz and a dissipation factor (tanδ) of 0.22 measured at 20°C/120 Hz, enabling efficient high-frequency performance.
• High ripple current capability: Low-frequency ripple current of 1.625 A (120 Hz) and high-frequency ripple current of 3.25 A (10 kHz), suitable for power-supply filtering and decoupling under dynamic load.
• Leakage current: Specified leakage current of 825 µA, allowing predictable standby and quiescent current behavior.
• Industry and environmental compliance: AEC-Q200 rated and RoHS compliant, aligning with automotive and regulated-environment requirements.

Typical Applications

• Automotive electronics: Suited for vehicle power rails and modules where AEC-Q200 qualification and 125°C endurance are required.
• High-temperature power supplies: Bulk smoothing and energy storage in power stages and converters that operate in elevated-temperature environments.
• Surface-mount power modules: Compact SMD assemblies that need automated placement—embossed carrier taping supports efficient PCB assembly.
• Industrial controls: Power decoupling and transient energy buffering in industrial systems exposed to wide temperature ranges.

Unique Advantages

• High capacitance in an SMD can: 3300 µF provides large bulk energy storage while keeping a compact footprint for space-constrained designs.
• High-temperature endurance: 4000 hours at 125°C supports extended lifetime in thermally demanding applications.
• Low ESR for efficient operation: 32 mΩ (100 kHz) reduces power loss and heating, improving reliability under ripple conditions.
• Robust ripple handling: Specified ripple currents at both low and high frequencies enable reliable filtering across typical switching and line-frequency scenarios.
• AEC-Q200 qualification: Provides an added level of assurance for automotive and other high-reliability system requirements.
• Assembly-ready packaging: Embossed carrier taping simplifies automated placement and volume manufacturing.
