UCL1E681MNL1GS

The UCL1E681MNL1GS is a Nichicon UCL series surface-mount aluminum electrolytic capacitor offering 680 µF capacitance at a 25 V rating in a compact φ10 × 13.5 mm can. It is a chip-type, low-impedance capacitor designed for space-constrained board designs that require high capacitance density and reliable performance across a wide temperature range.

Targeted for automotive and industrial electronic modules, the part combines AEC-Q200 qualification with a −55 °C to 105 °C operating range and a 2000-hour endurance at 105 °C, delivering a balance of electrical performance and long-term reliability for demanding environments.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance with ±20% tolerance at 120 Hz, 20 °C and a 25 V rated voltage suitable for many 12–24 V system designs.
• Low Impedance — Low impedance construction with 60 mΩ impedance to support stable performance under load.
• Loss Angle (tan δ) — tanδ of 0.14 measured at 20 °C, 120 Hz (rated voltage condition) for predictable AC behavior.
• Ripple Current Capability — Handles 595 mA at 120 Hz (low frequency) and 1.19 A at 10 kHz (high frequency), suitable for applications with significant ripple currents.
• Leakage & Reliability — Measured leakage current of 170 µA and endurance rated for 2000 hours at 105 °C to support long-term operation.
• Automotive Qualification & Temperature Range — AEC-Q200 rated with an operating temperature range of −55 °C to 105 °C for qualification in automotive electronic assemblies.
• Package & Mounting — φ10 × 13.5 mm radial SMD can (chip-type) packaged for surface-mount placement; supplied in embossed carrier taping for automated assembly. Recommended surface-mount land size: 1.03 × 1.03 cm.

Typical Applications

• Automotive electronic modules — AEC-Q200-rated capacitor suitable for use in control modules and power electronics where 25 V systems and extended temperature ranges are present.
• High-density power PCBs — Compact φ10 × 13.5 mm SMD can provides 680 µF capacitance for space-constrained power-supply and decoupling locations.
• High-ripple environments — Designed to support applications with significant ripple current demands, specified at 595 mA (120 Hz) and 1.19 A (10 kHz).

Unique Advantages

• AEC-Q200 Qualification: Ensures the capacitor meets automotive-grade reliability criteria required for vehicle electronics.
• High Capacitance in a Compact SMD Can: 680 µF in a φ10 × 13.5 mm package reduces board area compared with larger through-hole parts.
• Robust Thermal Endurance: Rated for 2000 hours at 105 °C, supporting long-term stability in elevated-temperature environments.
• Designed for High Ripple Loads: Specified ripple current ratings at both low and high frequencies enable use where AC stress and switching noise are present.
• Manufacturing-Ready Packaging: Supplied in embossed carrier taping for compatibility with automated pick-and-place and reflow processes.
