UCZ1E332MNS1MS

The UCZ1E332MNS1MS from Nichicon is a chip-type aluminum electrolytic capacitor in the UCZ series designed for high-reliability, high-temperature applications. It is a polarized surface-mount device specified for operation from -40°C to +125°C and is AEC-Q200 qualified.

Engineered for automated assembly, this part offers a high capacitance (3.3 mF / 3300 µF) at 25 V with defined low-temperature ESR and robust ripple-current capability, making it suitable for demanding power-management roles in temperature-challenged environments.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 µF) rated at 25 V with ±20% tolerance, providing bulk energy storage for power supply smoothing and decoupling.
• High Temperature Operation — Specified for continuous operation from -40°C to +125°C, supporting designs that require extended-temperature endurance.
• Low-Temperature ESR Specified — ESR characterized at low temperature including a specified value after -40°C testing, with an example ESR of 32 mΩ measured at 100 kHz.
• High Endurance — Designed for long life at elevated temperature, with endurance defined up to 4000 hours at 125°C in the UCZ series specification.
• Ripple Current Capability — Defined ripple current ratings of 1.625 A at 120 Hz and 3.25 A at 10 kHz help manage AC stress in power conversion and filtering circuits.
• Surface-Mount Compatibility — Chip-type, radial can SMD package intended for automated placement and carrier-tape feeding, simplifying high-volume assembly.
• AEC-Q200 Qualified — Meets AEC-Q200 qualification as noted in the product data, supporting use where that qualification is required.

Typical Applications

• Automotive electronic modules — Bulk filtering and energy buffering in automotive control units where AEC-Q200 qualification and wide temperature range are required.
• Power supply smoothing — Output filtering and decoupling in DC–DC converters and regulators operating in elevated-temperature environments.
• High-reliability embedded systems — Energy storage and transient suppression in systems that require defined low-temperature ESR and long-term endurance at high temperature.

Unique Advantages

• High-temperature endurance: Endurance specified up to 4000 hours at 125°C, enabling sustained performance in thermally demanding installations.
• Low-temperature ESR characterization: ESR specified following -40°C testing and a measured ESR of 32 mΩ at 100 kHz, providing predictable performance across the full operating range.
• Defined ripple handling: Rated ripple currents (1.625 A at 120 Hz, 3.25 A at 10 kHz) support effective AC current handling for power-conversion applications.
• Automated assembly ready: Chip-type SMD design and compatibility with carrier-tape feeding streamline high-volume PCB assembly.
• AEC-Q200 qualification: Qualification noted in the product data for designs that require that level of component qualification.
• Clear electrical envelope: Polarized 3.3 mF at 25 V with ±20% tolerance and specified leakage and tan δ characteristics for predictable circuit behavior.
