UCD1K680MNJ1MS

The UCD1K680MNJ1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount applications. It delivers 68 µF capacitance at an 80 V rating and is optimized for compact, high-density PCB assemblies.

Engineered with long endurance and robust electrical performance, this SMD capacitor targets automotive and other demanding environments where high temperature capability, low impedance, and reliable ripple handling are required.

Key Features

• Core Electricals  68 µF nominal capacitance with ±20% tolerance and an 80 V rated voltage. Tangent of loss angle (tan δ) is 0.08 measured at 20°C, 120 Hz.
• Low Impedance & Ripple Handling  Chip-type construction for low impedance; specified ripple currents are 250 mA at 120 Hz and 500 mA at 10 kHz to support power smoothing and decoupling in compact designs.
• Reliability & Endurance  Lifetime specified at 5000 hours at 105°C. Leakage current specified as 54.4 µA and performance limits for capacitance and tan δ after endurance testing are defined in the datasheet.
• Automotive-Grade Qualification  AEC-Q200 qualified, supporting use in automotive electronics and other applications requiring industry-recognized component qualification.
• Wide Operating Temperature  Rated for −55°C to +105°C to cover a broad range of environmental conditions.
• Surface-Mount Package  Chip type, radial can SMD in a φ12.5 × 13.5 mm case (L: 1.35 × D: 1.25 cm); supplied in embossed carrier taping for automated placement. Status: Mass Production.
• Regulatory Compliance  RoHS compliant.

Typical Applications

• Automotive Electronics  AEC-Q200 qualification and high-temperature endurance make this capacitor suitable for automotive control modules and sensor electronics requiring long-term reliability.
• High-Density PCB Power Modules  Chip-type SMD format and embossed carrier taping support automated placement in compact power supply and power-management assemblies on high-density boards.
• Power Filtering and Smoothing  Low impedance and specified ripple current ratings allow this capacitor to be used for local decoupling, smoothing, and energy buffering in DC–DC stages and power rails.

Unique Advantages

• High voltage capability in a compact SMD package: 80 V rating combined with a φ12.5 × 13.5 mm chip-style can provides higher voltage handling without a large board footprint.
• Designed for automated assembly: Embossed carrier taping packaging enables reliable pick-and-place and reflow-compatible processes for volume manufacture.
• Long endurance at elevated temperature: Specified 5000 hours at 105°C supports designs that require sustained operation in hot environments.
• Validated for automotive use: AEC-Q200 qualification and RoHS compliance simplify selection for regulated and automotive-grade applications.
• Measured low-loss behavior: Low tan δ (0.08 at 20°C, 120 Hz) and controlled leakage current support stable performance in AC and pulsed environments.
