UUE1H331MNS1MS

The UUE1H331MNS1MS is a chip‑type aluminum electrolytic capacitor designed for demanding, high‑temperature environments. As an AEC‑Q200 qualified, RoHS‑compliant SMD can, it is targeted at automotive electronics and other applications that require long life and thermal robustness.

Key attributes include a 330 µF capacitance at 50 V, an operating temperature range from −55 °C to 125 °C, and a rated load life of 5000 hours at 125 °C—providing stable bulk capacitance and leakage characteristics under heavy duty conditions.

Key Features

• Electrical performance — 330 µF nominal capacitance with ±20% tolerance and 50 V rated voltage for bulk energy storage and decoupling in high‑voltage circuits.
• High‑temperature endurance — Rated for 5000 hours at 125 °C; designed to retain capacitance and leakage performance after extended high‑temperature operation.
• Wide temperature range — Operates from −55 °C to 125 °C to support designs that must tolerate extreme ambient or internal heating conditions.
• Ripple current capability — Specified ripple performance of 569.5 mA at 120 Hz and 850 mA at 10 kHz to handle AC stress in power and filtering applications.
• Automotive qualification & environmental compliance — AEC‑Q200 qualified and RoHS compliant for use in regulated product designs.
• Surface‑mount chip can — Radial, can‑style SMD package with compact footprint (L: 16.5 mm × D: 16.0 mm; recommended land 16.3 × 16.3 mm) for space‑constrained PCBs.
• Polarized construction — Designed as a polarized electrolytic capacitor for DC bulk and filtering applications.

Typical Applications

• Automotive electronics — Bulk energy storage and power filtering in automotive modules where AEC‑Q200 qualification and high‑temperature endurance are required.
• High‑temperature power assemblies — SMD can capacitor for power rails and smoothing in electronics exposed to elevated operating temperatures.
• Surface‑mount power filtering — Decoupling and ripple suppression on compact PCBs requiring a radial can SMD capacitor with defined ripple current ratings.

Unique Advantages

• Long high‑temperature life: 5000 hours at 125 °C provides predictable end‑of‑life behavior for durable designs.
• Automotive‑grade reliability: AEC‑Q200 qualification supports usage in regulated automotive electronics and related sectors.
• Compact SMD can package: Radial SMD form factor and a small footprint enable integration into space‑limited boards while maintaining bulk capacitance.
• Documented ripple performance: Specified ripple currents at both low and high frequencies help engineers size components for thermal and electrical stress.
• Wide operating range: −55 °C to 125 °C operation supports designs that must tolerate extreme ambient and internal temperatures.
• RoHS compliance: Materials and manufacturing meet RoHS directive requirements for restricted substances.
