UCM1J821MNJ1MS

The UCM1J821MNJ1MS is a surface-mount, chip‑type aluminum electrolytic capacitor in the Nichicon UCM series. It delivers 820 µF at a rated voltage of 63 V with a chip‑type low‑impedance design and is supplied in embossed carrier taping for automated placement.

Designed for demanding temperature and lifetime requirements, this capacitor supports an operating range of −55 °C to +105 °C and a rated endurance of 5000 hours at 105 °C, making it suitable for electronics requiring stable capacitance, ripple handling and board‑level assembly efficiency.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 63 V and capacitance tolerance of −20% to +20%.
• Low‑Impedance Chip Type — Chip‑type, low impedance construction for improved AC performance as specified in the UCM series.
• Ripple Current Performance — Low‑frequency ripple current of 940 mA (120 Hz) and high‑frequency ripple current of 1.88 A (10 kHz), enabling effective ripple suppression at multiple frequencies.
• Temperature & Endurance — Rated for −55 °C to +105 °C with a life specification of 5000 hours at 105 °C.
• Leakage & Dissipation — Leakage current specified (516.6 µA) and tangent of loss angle (tan δ) of 0.08 at 20 °C, 120 Hz, consistent with series characteristics for 63 V parts.
• Surface‑Mount Package & Assembly — Radial, can‑style SMD package (φ18 × 16.5 mm) supplied in embossed carrier taping for compatibility with automatic mounting equipment.
• Automotive‑Grade Qualification — AEC‑Q200 qualified and RoHS compliant, enabling use in applications requiring component level automotive qualification.

Typical Applications

• Automotive electronics — AEC‑Q200 qualification, −55 °C to +105 °C temperature rating, and 5000 h endurance at 105 °C support use in automotive electronic modules where long‑term thermal performance is needed.
• Power rail smoothing and ripple control — 820 µF capacitance combined with specified ripple currents (940 mA @120 Hz, 1.88 A @10 kHz) provides bulk decoupling and ripple suppression on DC power rails.
• High‑volume automated assembly — Chip‑type SMD design and embossed carrier taping allow efficient placement with automatic mounting equipment, simplifying production flows.

Unique Advantages

• High capacitance in an SMD can — 820 µF in a φ18 × 16.5 mm chip‑type package provides substantial bulk energy storage while supporting surface‑mount assembly.
• Temperature resilience and long life — Rated for operation up to 105 °C with 5000 hours endurance at that temperature, delivering predictable aging and service life for thermal stress environments.
• Multifrequency ripple capability — Specified ripple current at both 120 Hz and 10 kHz gives designers data to size the capacitor for low‑ and high‑frequency ripple conditions.
• Automotive qualification and compliance — AEC‑Q200 qualification and RoHS compliance support regulated markets and supply chain requirements.
• Assembly‑friendly packaging — Embossed carrier taping is optimized for automatic placement, reducing manual handling and improving throughput.
