UCD1H681MNJ1MS

The UCD1H681MNJ1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount assembly on high-density PC boards. It delivers 680 µF capacitance at a 50 V rating with a wide operating temperature range of -55 °C to 105 °C and long endurance of 5000 hours at 105 °C.

Targeted for demanding environments, this SMD capacitor provides high ripple current capability, low leakage, and packaging compatible with automated mounting (embossed carrier taping), making it suitable for automotive electronics and other robust system-level power designs.

Key Features

• Electrical Performance — 680 µF capacitance with ±20% tolerance and rated voltage 50 V; specified tan δ (DF) of 0.10 measured at 20 °C, 120 Hz.
• Low Impedance / Ripple Handling — Low-frequency ripple current 805 mA at 120 Hz and high-frequency ripple current 1.61 A at 10 kHz to support power filtering and decoupling.
• Reliability & Endurance — Rated life of 5000 hours at 105 °C with specified limits on capacitance change, tan δ, and leakage after endurance testing.
• Temperature Range — Wide operating range from -55 °C to 105 °C for use across extreme environments.
• Leakage Current — Specified leakage current of 340 µA, measured after rated voltage application conditions.
• Package & Mounting — Chip-type radial can for surface mount (φ16 × 16.5L); supplied in embossed carrier taping compatible with automatic pick-and-place equipment. Surface mount land size: 1.63 × 1.63 cm.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant, supporting regulated and automotive-grade design requirements.

Typical Applications

• Automotive Electronics — Intended for automotive electronic modules that require AEC-Q200-qualified SMD bulk capacitance with high ripple handling and wide temperature endurance.

Unique Advantages

• High Bulk Capacitance in SMD Form — 680 µF in a chip-type package minimizes board area compared to discrete through-hole solutions while delivering substantial energy storage.
• High Ripple Capability — Dual ripple current ratings (805 mA at 120 Hz and 1.61 A at 10 kHz) let designers size capacitors for both low- and high-frequency power conditioning.
• Extended High-Temperature Lifetime — 5000 hours at 105 °C supports long-term operation in elevated-temperature environments common in power electronics and automotive applications.
• SMD Compatibility for Automated Assembly — Embossed carrier taping and a compact chip can package simplify placement on high-density PCBs and reduce assembly complexity.
• Qualification and Compliance — AEC-Q200 qualification and RoHS compliance provide conformity to automotive component requirements and environmental regulations.
