UCZ1E821MNQ1MS

The UCZ1E821MNQ1MS is a surface-mount aluminum electrolytic capacitor in Nichicon’s UCZ chip-type, high-reliability series. It delivers 820 µF of capacitance at a 25 V rated voltage in a compact φ12.5 × 13.5 mm can suitable for automated assembly with embossed carrier taping.

Designed for high-temperature operation and qualified to AEC‑Q200, this capacitor targets applications that require robust capacitance, elevated operating temperature capability, and measurable high-frequency performance characteristics.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 25 V and a capacitance tolerance of -20% to +20%.
• High-temperature rating — Rated operating temperature range of -40 °C to +125 °C with an endurance specification of 3000 hours at 125 °C.
• Low ESR and frequency performance — ESR of 60 mΩ measured at 100 kHz, supporting higher-frequency decoupling and lower loss in switching applications.
• Ripple current capability — Low-frequency ripple current of 850 mA (120 Hz) and high-frequency ripple current of 1.7 A (10 kHz), enabling effective smoothing under varying ripple spectra.
• Loss tangent (tan δ) — tan δ of 0.18 measured at 20 °C and 120 Hz, providing a quantifiable dissipation factor for design calculations.
• Leakage current — Specified leakage current of 205 µA.
• Surface-mount package — Chip-style radial can for SMD placement; packaged in embossed carrier taping for automated pick-and-place processes.
• Standards & compliance — AEC‑Q200 qualified and RoHS compliant.

Typical Applications

• Automotive electronic modules — AEC‑Q200 qualification and a -40 °C to +125 °C rating make this capacitor suitable for temperature‑elevated in-vehicle power and control modules.
• Power supply filtering — High ripple current capability and low ESR support bulk filtering and smoothing in DC–DC converter outputs.
• High-temperature industrial electronics — Endurance at 125 °C and chip-type SMD packaging suit industrial assemblies exposed to elevated ambient temperatures.

Unique Advantages

• High-temperature endurance: 3000 hours at 125 °C ensures predictable aging behavior for designs that operate at elevated temperatures.
• Measurable high-frequency performance: 60 mΩ ESR at 100 kHz and 1.7 A ripple at 10 kHz provide concrete metrics for high-frequency decoupling and thermal planning.
• Automated assembly ready: Embossed carrier taping and SMD chip package support high-volume pick-and-place manufacturing.
• Automotive-grade qualification: AEC‑Q200 rating supports use in applications requiring automotive-grade components.
• Compact, high-capacity form factor: 820 µF in a φ12.5 × 13.5 mm can delivers bulk capacitance in a small footprint for space-constrained boards.
