Overview of UCM1H821MNJ1MS – Aluminum Electrolytic Chip-Type Capacitor, 820 µF · 50 V

The UCM1H821MNJ1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount assembly. It delivers 820 µF capacitance at 50 V in a compact radial can SMD package (φ16 × 16.5 mm) and is supplied in embossed carrier taping for automated mounting.

Engineered for demanding temperature environments, this part is rated from −55 °C to +105 °C with a 5000-hour endurance at 105 °C and carries AEC-Q200 qualification, making it suitable for automotive and other high-reliability electronic systems.

Key Features

  • Capacitance & tolerance — 820 µF with ±20% tolerance measured at 120 Hz, 20 °C, providing bulk energy storage and decoupling in power systems.
  • Voltage rating — 50 V nominal rated voltage for mid-voltage power rails.
  • Low impedance design — Chip-type, low-impedance construction with a specified tanδ of 0.10 at 120 Hz, 20 °C for improved AC performance.
  • Ripple current capability — 910 mA at 120 Hz (low frequency) and 1.82 A at 10 kHz (high frequency) to support ripple and transient handling in power supplies.
  • Leakage current — 410 µA specified leakage current after rated voltage application, consistent with electrolytic behavior and system bias planning.
  • Temperature & endurance — Operates from −55 °C to +105 °C with a rated lifetime of 5000 hours at 105 °C.
  • Packaging & assembly — Radial can SMD chip in φ16 × 16.5 mm size, supplied in embossed carrier taping compatible with automatic mounting equipment.
  • Quality & compliance — AEC-Q200 qualified and RoHS compliant for regulated application environments.

Typical Applications

  • Automotive electronics — Suitable for use in automotive electrical systems where AEC-Q200 qualification and high-temperature endurance are required.
  • Surface-mount production — Designed for automated placement with embossed carrier taping to streamline PCB assembly flows.
  • High-temperature power modules — Rated to +105 °C with 5000-hour endurance for power supply smoothing and bulk decoupling in elevated-temperature environments.

Unique Advantages

  • Robust temperature endurance — 5000 hours at 105 °C supports long-term operation in high-heat applications.
  • AEC-Q200 qualification — Provides a verified quality baseline for automotive and similarly demanding markets.
  • High ripple handling — Separate low- and high-frequency ripple current ratings (910 mA at 120 Hz, 1.82 A at 10 kHz) allow designers to size capacitors for both mains-frequency and switching-frequency stress.
  • Compact SMD form factor — φ16 × 16.5 mm radial can SMD delivers substantial capacitance in a board-mountable package.
  • Manufacturing-friendly supply — Embossed carrier taping supports automated placement and efficient production throughput.
  • Regulatory compliance — RoHS compliance for environmental and regulatory alignment.
