UCD1J681MNS1MS

The UCD1J681MNS1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface mounting on high-density PC boards. It delivers 680 µF at a 63 V rating with polarized construction and is optimized for automated assembly using carrier-tape feeding.

Qualified to AEC-Q200 and compliant with RoHS (2011/65/EU, (EU)2015/863), this component targets automotive and other high-reliability applications that require elevated temperature performance up to +105°C and extended endurance.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance, suitable where bulk capacitance at medium voltage is required.
• Low Impedance Chip Type — Chip-type construction specifically characterized for low impedance to support filtering and smoothing functions in power circuits.
• Temperature Range & Endurance — Rated for operation from −55°C to +105°C with a specified lifetime of 5000 hours at +105°C.
• AEC-Q200 Qualified — AEC-Q200 qualification is documented for use in applications requiring component-level automotive qualification.
• Surface-Mount Package — Radial, can-style SMD package designed for high-density PCBs and automated mounting with carrier tape; physical size L: 1.65 × D: 1.8 cm and recommended land size L: 1.83 × W: 1.83 cm.
• High Ripple Handling — Rated ripple currents of 845 mA at 120 Hz and 1.69 A at 10 kHz support AC ripple and switching power conditions.
• Polarized with Defined Leakage — Polarized electrolytic capacitor with leakage current specification: after 2 minutes at rated voltage and 20°C, leakage ≤ 0.01 CV or 3 µA, whichever is greater.
• RoHS Compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863) for restricted substances compliance.

Typical Applications

• Automotive Electronics — For use in automotive electronic modules where AEC-Q200 qualification and elevated-temperature endurance are required.
• High-Density SMD Power Modules — Suited to surface-mount power stages and DC bus smoothing on compact, densely populated PCBs.
• Rugged Electronics — Applicable to electronic systems that operate across −55°C to +105°C and demand sustained performance at elevated temperature over time.

Unique Advantages

• Designed for Automated Assembly — Carrier-tape compatibility enables high-volume pick-and-place production for consistent board-level assembly.
• Qualified for Automotive Use — AEC-Q200 qualification supports integration into automotive designs with defined component-level reliability requirements.
• High-Temperature Endurance — Specified 5000 hours at +105°C provides a predictable endurance profile for long-term thermal stress.
• Measured Ripple Performance — Published ripple current ratings at 120 Hz and 10 kHz allow designers to size capacitors against real switching and ripple conditions.
• Compact SMD Can Package — Radial can-style SMD footprint and defined land pattern simplify PCB layout for high-density designs.
• Regulatory Compliance — RoHS compliance simplifies regulatory requirements for product deployment in many markets.
