UCD0J681MNS1GS

The UCD0J681MNS1GS is a chip-type, low-impedance aluminum electrolytic capacitor in a compact surface-mount can designed for high-density PCBs. It delivers 680 µF at 6.3 V with measured loss tangent (tanδ) of 0.26 (20°C, 120 Hz), making it suitable where bulk capacitance and low impedance density are required.

Engineered for robust environments, this part supports a wide operating temperature range from -55°C to 105°C, a 5000-hour endurance at 105°C, AEC-Q200 qualification, and embossed carrier taping for automated placement—attributes that target demanding automotive and industrial assembly processes.

Key Features

• Electrical Performance — 680 µF capacitance rated at 6.3 V with a capacitance tolerance of -20% to +20% and a tanδ (DF) of 0.26 measured at 20°C, 120 Hz, supporting stable bulk capacitance in low-voltage systems.
• Ripple Handling — Low-frequency ripple current 300 mA (120 Hz) and high-frequency ripple current 600 mA (10 kHz) for improved smoothing and transient support in power rails.
• Reliability & Endurance — Long-life endurance of 5000 hours at 105°C and AEC-Q200 qualification for applications requiring higher reliability and extended thermal stress performance.
• Wide Temperature Range — Operates from -55°C to 105°C for use across broad environmental conditions.
• Compact SMD Package — Chip-type radial can for surface mount (φ8 × 10L, size L: 1 × D: 0.8 cm) with recommended land size 8.3 × 8.3 mm, optimized for high-density board layouts.
• Assembly-Friendly Packaging — Supplied in embossed carrier taping compatible with automatic mounting machines; vibration resistant for robust assembly and in-field durability.
• Low Leakage — Specified leakage current of 42.84 µA, enabling predictable standby and bias performance after application of rated voltage.

Typical Applications

• Automotive electronic systems — AEC-Q200-qualified component suitable for automotive modules that require bulk capacitance and wide-temperature endurance.
• Power management and decoupling — Compact, low-impedance 680 µF capacitance with defined LF and HF ripple ratings for smoothing and local energy buffering on low-voltage rails.
• High-density surface-mount assemblies — Chip-type can and embossed carrier taping enable automated placement on compact PCBs where space and assembly throughput are priorities.

Unique Advantages

• AEC-Q200 qualification — Provides an established baseline for automotive-grade reliability where that qualification is required.
• High-temperature endurance — 5000 hours at 105°C supports long-term operation under elevated thermal stress, reducing need for frequent redesigns.
• Broad operating range — −55°C to 105°C supports use across harsh ambient conditions and temperature cycling.
• Balanced ripple capability — Defined low- and high-frequency ripple currents (300 mA @120 Hz, 600 mA @10 kHz) let designers quantify margin for both mains-frequency and switching-frequency noise.
• Automated assembly ready — Embossed carrier taping and surface-mount form factor simplify pick-and-place integration and support higher PCB assembly throughput.
• Predictable leakage and loss — Specified leakage current (42.84 µA) and tanδ provide measurable parameters for budgeting power loss and standby drain.
