UCX1H821MNS1MS

The UCX1H821MNS1MS is a chip-type aluminum electrolytic capacitor from Nichicon’s UCX series designed for high-temperature, surface-mount applications. It delivers 820 µF at 50 V in a compact radial can SMD package, with specifications tailored for sustained operation to +135°C and AEC‑Q200 qualification.

Typical use cases include automotive and other high-temperature power electronics where robust capacitance, controlled ESR, and automated assembly compatibility are required. Key value propositions include high-temperature endurance, defined ESR and ripple handling, and tape-and-reel mounting support for automated placement.

Key Features

• High‑temperature endurance – Rated for continuous operation from -40°C to +135°C with a specified 2000 hours endurance at 135°C.
• AEC‑Q200 Qualified – Designed to meet automotive-grade reliability requirements (AEC‑Q200 qualification stated).
• Electrical performance – 820 µF nominal capacitance at 50 V with ±20% tolerance and a low‑temperature ESR specification taken into account after -40°C testing.
• Low ESR and ripple capability – ESR specified at 70 mΩ (measured at 100 kHz) with ripple current ratings of 600 mA at 120 Hz and 1.2 A at 10 kHz.
• Surface-mount, automated assembly – Radial, can-style SMD package compatible with carrier-tape feeding for automatic mounting machines; recommended land size L: 1.83 × W: 1.83 cm.
• Regulatory compliance – RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive power rails – Suited for systems requiring AEC‑Q200 qualification and continuous operation at elevated temperatures up to +135°C.
• High‑temperature electronics – Energy storage and smoothing in electronics exposed to sustained high ambient temperatures, supported by a 2000‑hour rating at 135°C.
• Surface‑mount power modules – Compact radial can SMD form factor and carrier‑tape compatibility enable automated placement into power assemblies and modules.
• High‑frequency ripple suppression – Low ESR (70 mΩ at 100 kHz) and specified ripple current ratings help stabilize high-frequency DC power lines.

Unique Advantages

• Specifically rated for +135°C operation: 2000 hours endurance at 135°C provides predictable long‑term performance in high‑temperature designs.
• AEC‑Q200 qualification: Provides an established reliability baseline for automotive and other demanding applications.
• ESR characterized across temperature: ESR specification added after -40°C testing ensures defined behavior across the product’s operating range.
• Automated assembly ready: Carrier‑tape compatibility and an SMD radial can package simplify integration into high-volume manufacturing flows.
• Measured ripple handling: Clear ripple current ratings at 120 Hz and 10 kHz let engineers size the capacitor for real-world power filtering needs.
• RoHS compliant: Meets current environmental directives for use in regulated markets.
