UUJ1J680MNQ1MS

The UUJ1J680MNQ1MS is a chip‑type aluminum electrolytic capacitor in a surface‑mount, can style package designed for high‑density PC board assembly. It delivers 68 µF capacitance at a 63 V rating with polarized construction for use where compact bulk capacitance is required.

Designed for automated carrier‑tape mounting, this part is targeted at automotive and industrial electronics where extended high‑temperature endurance and component qualification matter. Key value propositions include AEC‑Q200 qualification, RoHS compliance, and a rated operating range to 105°C with a proven 5000‑hour endurance at that temperature.

Key Features

• Electrical performance — 68 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance; polarized construction suitable for DC bulk and decoupling applications.
• Ripple handling — Specified ripple current of 175 mA at 120 Hz and 350 mA at 10 kHz, supporting common power‑supply filtering and smoothing tasks.
• Package & mounting — Chip‑type, radial can SMD package engineered for surface mounting on high‑density PCBs and compatibility with automatic carrier‑tape mounting equipment.
• Thermal and endurance — Operating temperature range to -55°C to +105°C and rated for 5000 hours at 105°C with capacitance change within ±20% and leakage current within initial specified limits after test.
• Qualification & compliance — AEC‑Q200 qualified and RoHS compliant, providing documented reliability for regulated environments.
• Electrical stability at temperature — Low‑temperature impedance characteristics and a tan δ max of 0.10 at the 63 V rating (measured at 120 Hz, 20°C), supporting predictable performance across temperature extremes.
• Compact footprint — Physical dimensions L: 1.35 × D: 1.25 cm with recommended PCB land size L: 1.28 × W: 1.28 cm for reliable soldering and placement.

Typical Applications

• Automotive power modules — Bulk decoupling and smoothing in automotive power supplies, leveraging the 63 V rating, AEC‑Q200 qualification, and 5000 h endurance at 105°C.
• Electronic control units (ECUs) — Stable capacitance and specified ripple handling for control electronics operating across -55°C to +105°C.
• Infotainment and telematics — Compact surface‑mount form factor and carrier‑tape compatibility for high‑density boards used in vehicle infotainment and communications modules.

Unique Advantages

• AEC‑Q200 qualification: Provides a documented level of automotive‑grade reliability for designs requiring component qualification.
• High‑temperature endurance: Rated for 5000 hours at 105°C, enabling long‑life performance in elevated operating environments.
• Surface‑mount, automated assembly‑friendly: Chip‑type construction and carrier‑tape compatibility streamline placement on high‑density PCBs and automated production lines.
• Measurable ripple performance: Defined ripple current ratings at 120 Hz and 10 kHz allow engineers to size capacitors against known power‑supply ripple profiles.
• RoHS compliant: Conforms to relevant RoHS directives for regulated markets and product lines.
• Predictable low‑temperature behavior: Documented impedance ratios and tan δ limits support design validation across temperature extremes.
