UCL1E331MNL1GS

The UCL1E331MNL1GS is a chip‑type, low‑impedance aluminum electrolytic capacitor in a surface‑mount can designed for demanding electronic environments. With a rated capacitance of 330 µF at 25 V and AEC‑Q200 rating, it targets applications that require robust performance across a wide temperature range and extended endurance.

Key value propositions include low impedance and high ripple handling for improved power filtering, compact SMD packaging for board‑level integration, and endurance tested to 2000 hours at 105 °C for long‑term reliability.

Key Features

• Capacitance and Voltage — 330 µF rated capacitance at 25 V with tolerance of −20% to +20%.
• Low Impedance — Specified impedance of 80 mΩ supports reduced voltage ripple and improved transient response.
• High Ripple Current — Rated low‑frequency ripple current of 425 mA (120 Hz) and high‑frequency ripple current of 850 mA (10 kHz) to handle AC stress in power circuits.
• Loss Characteristics — tanδ (DF) of 0.14 measured at 20 °C, 120 Hz, for predictable dissipation behavior.
• Leakage Current — Specified leakage current of 82.5 µA at rated conditions to help manage standby and leakage budgets.
• Temperature and Endurance — Operating range from −55 °C to +105 °C and endurance rated at 2000 hours at 105 °C.
• Automotive Qualification — AEC‑Q200 rated for use in applications requiring component-level automotive reliability.
• Package and Mounting — φ8 × 10 mm can (radial, can – SMD) in an embossed carrier taping format; surface mount land size 8.3 × 8.3 mm for PCB layout.
• Polarized Device — Polar capacitor for correct polarity installation in DC circuits.

Typical Applications

• Automotive electronics — Suitable for automotive electronic modules where AEC‑Q200 qualification and an operating range of −55 °C to +105 °C are required.
• PCB power-conditioning — Compact surface‑mount can and low impedance support local decoupling and smoothing on power rails in board‑level power designs.
• Heat‑stressed environments — Endurance rating of 2000 hours at 105 °C and embossed carrier taping make this part appropriate for assemblies exposed to elevated operating temperatures and automated placement.

Unique Advantages

• Low AC impedance: 80 mΩ impedance reduces ripple voltage and improves regulator stability.
• High ripple handling: 425 mA (120 Hz) and 850 mA (10 kHz) ripple current ratings permit effective handling of both low‑ and high‑frequency AC components.
• Wide temperature capability: −55 °C to +105 °C operation supports designs across harsh thermal ranges.
• Automotive‑grade reliability: AEC‑Q200 rating provides a verified level of quality for vehicle electronics.
• Compact SMD form factor: φ8×10 mm can and 8.3×8.3 mm land pattern simplify board integration while maintaining capacitance density.
• Long endurance: 2000 hours at 105 °C demonstrates sustained performance under elevated temperatures.
