UCD1H681MNS1MS

The UCD1H681MNS1MS is a chip‑type, low‑impedance aluminum electrolytic capacitor designed for surface mounting on high‑density PC boards. It delivers 680 µF at 50 V in a compact SMD radial can package built for automated assembly and long-term high‑temperature operation.

Targeted use cases include automotive and other demanding electronics where extended high‑temperature endurance, reliable ripple handling, and tape‑feed compatibility for pick‑and‑place assembly are required. The device is RoHS compliant and AEC‑Q200 qualified.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 50 V provides bulk energy storage and smoothing in power rails.
• Low‑Impedance Chip Construction — Chip‑type low impedance design for improved AC performance and reduced ESR in compact SMD form factor.
• High Temperature Range — Operating temperature from −55 °C to +105 °C, supporting applications with elevated ambient temperatures.
• Long Endurance — Rated for 5,000 hours at 105 °C (per endurance conditions), enabling extended service life under high‑temperature stress.
• Ripple Current Capability — Rated ripple currents of 805 mA at 120 Hz and 1.61 A at 10 kHz for effective filtering in both low and high frequency environments.
• Tight Manufacturing & Assembly Fit — Surface mount radial can package with dimensions L: 1.65 × D: 1.6 cm and recommended land size L: 1.63 × W: 1.63 cm; compatible with carrier tape for automated placement.
• Electrical Quality — Capacitance tolerance ±20% and leakage current specified as ≤0.01 CV or 3 µA (whichever is greater) after 2 minutes at 20 °C.
• Compliance & Qualification — RoHS compliant and AEC‑Q200 qualified for applications requiring industry standard environmental and reliability controls.

Typical Applications

• Automotive Electronic Modules — Bulk and smoothing capacitor for vehicle ECUs and power modules where high temperature endurance and AEC‑Q200 qualification are required.
• High‑Density Surface‑Mount PCBs — Designed for compact SMD layouts and automated assembly using carrier tape, suited to space‑constrained power systems.
• Power Supply Filtering — Supports DC‑link and output filtering in power converters with specified ripple current ratings for both low and high frequency operation.

Unique Advantages

• High‑Temperature Endurance: 5,000 hours at 105 °C extends lifetime in thermally stressed environments.
• Low Impedance Performance: Chip‑type low impedance construction reduces AC losses and improves ripple handling at both 120 Hz and 10 kHz.
• Automated Assembly Ready: Carrier‑tape compatibility and surface‑mount radial can package streamline pick‑and‑place production.
• Automotive Qualification: AEC‑Q200 rating supports use in automotive electronic designs that require supplier qualification.
• Regulatory Compliance: RoHS compliance ensures adherence to current environmental directive requirements.
