UCD1C681MNL1GS

The UCD1C681MNL1GS is a chip-type, low-impedance aluminum electrolytic capacitor in a surface-mount can package. Engineered for high-density PCB assembly, this 680 µF, 16 V capacitor delivers bulk energy storage and smoothing where elevated temperature endurance and robust ripple handling are required.

Targeted at automotive and industrial power applications, the part combines a wide operating temperature range (−55 °C to +105 °C), AEC‑Q200 qualification, and tape-and-reel packaging for automated placement, offering a reliable SMD option for demanding power-rail designs.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance with a 16 V rated voltage and ±20% tolerance for bulk filtering and energy storage.
• Low Impedance Chip Type — Chip-type, low-impedance construction optimized for reduced ESR and improved ripple performance.
• Ripple Current Capability — Specified low-frequency ripple current of 425 mA (120 Hz) and high-frequency ripple current of 850 mA (10 kHz) to support power conditioning and converter output filtering.
• Loss Tangent — tan δ = 0.16 (measured at 20 °C, 120 Hz, 16 V) for predictable AC loss behavior in filtering applications.
• High Temperature Endurance — Rated for operation from −55 °C to +105 °C with a life/endurance specification of 5000 hours at 105 °C.
• Automotive Qualification — AEC‑Q200 rated, suitable for automotive electronic applications requiring qualified components.
• Surface-Mount Package — Compact φ10 × 10 mm can (radial, can - SMD) designed for surface mounting; supplied in embossed carrier taping for automatic placement.
• Environmental Compliance — RoHS compliant, supporting regulatory and environmental requirements.

Typical Applications

• Automotive power rails — Bulk smoothing and decoupling on 12 V/16 V systems where AEC‑Q200 qualification and high-temperature endurance are required.
• DC–DC converter outputs — Output filtering for converters benefiting from high ripple current capability at both low (120 Hz) and high (10 kHz) frequencies.
• ECU and control modules — Bulk energy reservoir and transient suppression in electronic control units operating across −55 °C to +105 °C.
• Power conditioning and smoothing — General-purpose smoothing on power distribution boards where low impedance and predictable tan δ are important.

Unique Advantages

• Proven high-temperature endurance: 5000 hours at 105 °C provides long-term stability for thermally demanding environments.
• AEC‑Q200 qualification: Enables use in automotive electronic systems that require qualified componentry.
• Dual-frequency ripple handling: Rated ripple currents at 120 Hz and 10 kHz support both mains-related and switching-regulator disturbances.
• Low loss behavior: Specified tan δ (0.16 at 16 V, 120 Hz) delivers predictable AC loss for filtering and smoothing tasks.
• SMD-ready packaging: φ10 × 10 mm chip can in embossed carrier taping streamlines automated assembly for high-volume production.
• Regulatory compliance: RoHS conformity supports environmental requirements for product builds.
