UCN1V331MCL1GS

The UCN1V331MCL1GS is a chip‑type aluminum electrolytic capacitor designed for high‑reliability surface‑mount applications. It delivers 330 µF at 35 V in a compact radial can SMD package with polarized terminals.

Built for demanding thermal and lifecycle requirements, this part is AEC‑Q200 qualified, RoHS compliant, and specified for operation from −40 °C to +125 °C with a rated lifetime of 3000 hours at 125 °C. Low ESR and specified ripple current ratings make it well suited for power filtering and decoupling in rugged environments.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a rated voltage of 35 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• Low ESR — Equivalent series resistance of 300 mΩ (measured at 100 kHz), enabling effective filtering and reduced power loss in high‑frequency circuits.
• High Temperature Endurance — Operating temperature range −40 °C to +125 °C and endurance specified as 3000 hours at 125 °C under rated voltage.
• Ripple Current Capability — Rated ripple current of 135 mA at 120 Hz and 270 mA at 10 kHz, supporting both low‑ and high‑frequency filtering tasks.
• Mounting & Package — Surface mount radial can (Chip type) in a compact footprint (L: 1.0 × D: 0.8 cm) with a recommended PCB land size of 8.3 × 8.3 mm.
• Industry Compliance — AEC‑Q200 qualified and RoHS compliant to the 2011/65/EU and (EU)2015/863 directives.

Typical Applications

• Automotive electronic control units (ECUs) — Provides bulk filtering and smoothing where AEC‑Q200 qualification and long‑term high‑temperature endurance are required.
• DC‑DC converters and power rails — Low ESR and defined ripple current ratings support stable voltage regulation and reduced output noise.
• Industrial power supplies — Compact SMD radial can accommodates board space constraints while delivering reliable high‑temperature performance.
• Telematics and onboard modules — Suitable for modules that require robust filtering under wide temperature swings and long operational life.

Unique Advantages

• Designed for reliability: AEC‑Q200 qualification and a 3000‑hour lifetime at 125 °C provide documented endurance for demanding applications.
• Performance under stress: Low ESR (300 mΩ at 100 kHz) and specified ripple currents (135 mA @120 Hz, 270 mA @10 kHz) help maintain circuit stability and reduce thermal stress.
• Compact SMD form factor: Chip‑type radial can package with a small footprint and specified PCB land pattern simplifies layout in space‑constrained designs.
• Wide temperature range: −40 °C to +125 °C operation supports use across automotive and industrial temperature environments.
• Regulatory compliance: RoHS conformity ensures compatibility with modern environmental requirements.
