UBC1E681MNS1MS

The UBC1E681MNS1MS is a chip-type aluminum electrolytic capacitor from Nichicon's UBC series designed for demanding, high-temperature environments. It is a surface-mount, polarized capacitor specified at 680 µF and 25 V, engineered for applications that require long-term reliability under elevated temperatures and vibration exposure.

Targeted at heavy-duty electronics—particularly automotive systems—the part delivers proven endurance at +150°C and is qualified to AEC-Q200 with RoHS compliance, providing a specification-driven choice for designs that must tolerate heat and mechanical stress.

Key Features

• High capacitance and voltage: 680 µF at 25 V provides bulk energy storage for power smoothing and decoupling in compact SMD form.
• High-temperature endurance: Rated operating range to 150°C with a specified load life of 1000 hours at +150°C for sustained performance in extreme thermal conditions.
• Vibration-resistant chip construction: Chip-type design optimized for vibration resistance, suitable where mechanical stability is required.
• Surface-mount, radial can package: SMD mounting with a compact case size (L: 1.65 × D: 1.6 cm) and recommended land size (L: 1.63 × W: 1.63 cm) for PCB assembly.
• Ripple handling: Rated ripple currents of 536 mA at 120 Hz and 800 mA at 10 kHz to support power-line filtering and transient suppression across frequency ranges.
• Industry qualification and compliance: AEC-Q200 qualified and RoHS compliant, aligning with automotive and regulated-environment requirements.
• Tolerance and polarization: ±20% capacitance tolerance at 120 Hz, 20°C; polarized device for correct orientation in circuits.

Typical Applications

• Automotive electronics: Suited for control modules and electronic subsystems that require components qualified to AEC-Q200 and able to operate at elevated temperatures.
• Power supply smoothing: Bulk decoupling and filtering in high-temperature power rails where 680 µF at 25 V and specified ripple handling are required.
• Vibration-prone environments: Use in equipment or assemblies exposed to mechanical vibration where the chip-type, vibration-resistant construction improves reliability.

Unique Advantages

• High-temperature reliability: 1000-hour load life at +150°C provides a measurable endurance metric for thermal stress environments.
• Automotive-grade qualification: AEC-Q200 rating supports deployment in automotive electronic designs that demand standardized component qualification.
• Practical ripple capacity: Specified ripple currents at both low and high frequencies help designers size capacitors for real-world power filtering requirements.
• Compact SMD format: Radial can surface-mount package with defined PCB land dimensions eases integration into space-constrained layouts.
• Regulatory compliance: RoHS-compliant construction helps meet environmental requirements for product development and manufacturing.
