UCZ1V681MNJ1MS

The UCZ1V681MNJ1MS is a 680 µF, 35 V aluminum electrolytic chip capacitor in a surface-mount can package, designed for high-temperature operation and automated assembly. It combines high capacitance with defined low-temperature ESR performance and ripple-handling capability to support demanding power-management and electronic control applications.

Targeted use cases include automotive electronic systems and other designs requiring operation across a wide temperature range (−40°C to 125°C) with AEC-Q200 qualification and RoHS compliance for long-term reliability and regulatory conformity.

Key Features

• Capacitance & Tolerance: 680 µF nominal with tolerance −20% to 20%, suitable where bulk capacitance is required in a compact SMD form factor.
• Rated Voltage: 35 V working voltage tuned for mid-voltage power rails.
• Low-Frequency and High-Frequency Ripple Capability: Ripple currents rated at 850 mA (120 Hz) and 1.7 A (10 kHz) to handle both low- and high-frequency ripple components in power circuits.
• Low ESR: 60 mΩ ESR measured at 20°C / 100 kHz, helping reduce losses and thermal rise under AC ripple.
• Loss Angle (tan δ): tan δ = 0.16 at 20°C, 120 Hz (for 35 V rating), providing predictable dissipation characteristics.
• Leakage Current: Specified leakage current of 238 µA for controlled standby loss behavior.
• High-Temperature Endurance: Rated lifetime of 3000 hours at 125°C, enabling extended service in elevated-temperature environments.
• Robust Packaging & Mounting: φ12.5 × 13.5 mm can (SMD radial can) in embossed carrier taping for compatibility with automated placement and reflow assembly.
• Qualification & Compliance: AEC-Q200 qualified and RoHS compliant, supporting regulated design requirements.

Typical Applications

• Automotive Electronics: Suitable for automotive ECUs and control modules where AEC-Q200 qualification, −40°C to 125°C operation and long endurance are required.
• Power Supply Filtering: Bulk smoothing and decoupling on DC power rails, leveraging 680 µF capacitance, 60 mΩ ESR and high ripple-current ratings.
• Surface-Mount Production Lines: Designed for automatic placement with embossed carrier taping and an SMD can package for streamlined assembly.

Unique Advantages

• Designed for elevated-temperature duty: 3000-hour endurance at 125°C supports sustained operation in hot environments.
• Automotive-grade qualification: AEC-Q200 rating provides qualification confidence for vehicle electronics and similarly demanding systems.
• High ripple tolerance with low ESR: 850 mA (120 Hz) and 1.7 A (10 kHz) ripple ratings paired with 60 mΩ ESR reduce heat generation and improve power-stage stability.
• Predictable loss characteristics: tan δ = 0.16 (20°C, 120 Hz) gives clear electrical dissipation behavior for thermal and circuit design.
• Assembly-ready SMD format: φ12.5×13.5 mm can in embossed carrier taping simplifies automated pick-and-place and reflow workflows.
• Regulatory compliance: RoHS conformity supports environmental and product compliance targets.
