Overview of UCX1V821MNS1MS – Chip type, +135°C rated, 820 µF, 35 V

The UCX1V821MNS1MS is a chip-type aluminum electrolytic capacitor designed for high-temperature operation up to +135°C. It delivers 820 µF capacitance at a 35 V rating in a compact surface-mount radial can package, and is intended for assemblies that require automated placement using carrier tape.

Built for demanding thermal and ripple environments, this AEC-Q200 qualified, RoHS-compliant part provides specified ESR performance after low-temperature testing and a rated endurance for long-duration high-temperature use.

Key Features

  • Electrical Performance — 820 µF capacitance at 35 V with ±20% tolerance, providing bulk energy storage and smoothing in power circuits.
  • High-temperature endurance — Rated for continuous operation from −40°C to +135°C with an endurance rating of 2000 hours at 135°C.
  • Low-temperature ESR specification — ESR is specified (50 mΩ at 100 kHz) and includes performance after test at −40°C, supporting stable behavior across temperature extremes.
  • Ripple handling — Rated ripple current of 600 mA at 120 Hz and 1.2 A at 10 kHz to support high-frequency and low-frequency ripple environments.
  • Surface-mount, carrier-tape compatible — Chip-type radial can packaged for surface-mount assemblies and compatible with automated mounting machines using carrier tape.
  • Standards and compliance — AEC-Q200 qualified and RoHS compliant, supporting regulated production and automotive-focused design requirements.

Typical Applications

  • Automotive electronics — Component-level energy storage and smoothing where AEC-Q200 qualification and high-temperature operation are required.
  • High-temperature power systems — Bulk decoupling and ripple suppression in electronics that operate continuously up to +135°C.
  • Surface-mount power assemblies — Automated placement-friendly packaging for high-density SMT boards requiring robust capacitance in a compact can-style footprint.

Unique Advantages

  • High-temperature rated with verified endurance — 2000 hours at 135°C provides measurable lifetime data for thermal design planning.
  • Specified low-temperature ESR — ESR characterized after −40°C testing (50 mΩ at 100 kHz) helps ensure predictable performance across the specified temperature range.
  • Dual-frequency ripple capability — Separate ripple current ratings for 120 Hz and 10 kHz allow designers to size capacitors for both low-frequency smoothing and higher-frequency ripple demands.
  • Automation-ready packaging — Carrier-tape compatibility enables efficient assembly in automated surface-mount production flows.
  • Automotive-focused qualification — AEC-Q200 qualification and RoHS compliance support regulated supply chains and long-term program planning.

Why Choose UCX1V821MNS1MS?

UCX1V821MNS1MS is positioned for designs that require a compact, high-capacitance surface-mount aluminum electrolytic capacitor capable of extended operation at elevated temperatures. Its combination of 820 µF at 35 V, verified ESR after low-temperature testing, high ripple current ratings, and a documented 2000-hour endurance at 135°C makes it suitable for thermal- and ripple-challenged power electronics.

This part is well suited to engineering teams and procurement looking for an AEC-Q200 qualified, RoHS-compliant SMD capacitor with automated assembly compatibility and clear, test-based performance data to support robust design validation and long-term deployment.
