UWZ1A681MCL1GS

The UWZ1A681MCL1GS is a chip‑type aluminum electrolytic capacitor designed for surface‑mount applications that demand wide operating temperature and proven endurance. This 680 µF, 10 V polarized capacitor combines high bulk capacitance with defined ripple current capability and is provided in an embossed carrier tape package for automated mounting.

Engineered with AEC‑Q200 qualification and RoHS compliance, the UWZ1 series supports designs that require long life at elevated temperatures, with rated operation from −55°C to +105°C and endurance of 1000 hours at 105°C.

Key Features

• Capacitance & Voltage 680 µF nominal capacitance at a rated voltage of 10 V with tolerance ±20% (120 Hz, 20°C).
• Loss Tangent (tan δ) tanδ = 0.24 (measurement condition: 20°C, 120 Hz) for stable AC loss characteristics.
• Ripple Current Capability Low‑frequency ripple current 310 mA (120 Hz) and high‑frequency ripple current 465 mA (10 kHz) for board‑level smoothing and decoupling under varying load frequencies.
• Leakage Current Specified leakage current 68 µA, supporting predictable bias behavior after application of rated voltage.
• Wide Temperature & Endurance Operating temperature −55°C to +105°C with endurance rated 1000 hours at 105°C.
• Assembly & Packaging Chip‑type surface‑mount design in φ10 × 10L (10 mm × 10 mm) package, supplied in embossed carrier tape for automated placement; compatible with high‑temperature reflow up to 260°C (refer to recommended reflow conditions).
• Quality & Compliance AEC‑Q200 qualified and RoHS compliant, providing traceable qualification and environmental compliance for regulated designs.

Typical Applications

• Automotive electronics — AEC‑Q200 qualification plus −55°C to +105°C operation and 1000 h life at 105°C make this capacitor suitable for use in automotive electronic modules that require qualified components.
• Board‑level power filtering — 680 µF bulk capacitance combined with specified ripple currents (310 mA at 120 Hz, 465 mA at 10 kHz) addresses smoothing and decoupling needs on low‑voltage power rails.
• Automated surface‑mount assembly — Chip format with embossed carrier tape and 260°C peak reflow compatibility supports high‑volume SMT production and reliable soldering performance.

Unique Advantages

• High bulk capacitance in an SMD chip — 680 µF in a compact φ10 × 10L package reduces board area required for bulk energy storage.
• Defined ripple performance — Separate low‑ and high‑frequency ripple current ratings let designers verify thermal and ripple requirements across typical operating frequencies.
• Wide operating temperature with proven endurance — −55°C to +105°C range and 1000 hours at 105°C provide predictable lifetime behavior in thermally demanding environments.
• Automotive‑grade qualification — AEC‑Q200 listing supports use in designs requiring industry qualification and traceability.
• SMT‑friendly packaging — Embossed carrier tape and 260°C reflow compatibility enable efficient automated placement and conventional surface‑mount assembly flows.
• Regulatory compliance — RoHS compliance for regulated markets and environmental requirements.
