UCM1K221MNJ1MS

The UCM1K221MNJ1MS is a surface-mount aluminum electrolytic chip capacitor in Nichicon’s UCM series, designed for low-impedance applications. It delivers 220 µF at a rated voltage of 80 V in a compact φ12.5 × 13.5 mm can package with embossed carrier taping for automated assembly.

Targeted for demanding environments, this AEC-Q200 qualified part supports an operating temperature range of -55 °C to 105 °C and a rated endurance of 5000 hours at 105 °C, making it suitable for automotive and other high-reliability systems.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 80 V and ±20% tolerance (measured at 120 Hz, 20 °C).
• Low Loss / Low Impedance — tan δ (loss tangent) of 0.08 measured at 120 Hz and 20 °C, supporting stable performance in AC and ripple conditions.
• Ripple Current Handling — 525 mA at 120 Hz (low frequency) and 1.05 A at 10 kHz (high frequency) for decoupling and filtering under varying load frequencies.
• Leakage Current — Specified leakage current of 176 µA, suitable for power supply and energy storage applications requiring controlled leakage.
• High-Temperature Endurance — Rated life of 5000 hours at 105 °C, with endurance characteristics defined after restoration to 20 °C following the life test.
• Robust Package & Mounting — Chip-type radial can (SMD) with embossed carrier taping for automatic pick-and-place assembly; recommended surface-mount land size 1.28 × 1.28 cm.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant for regulated manufacturing environments.

Typical Applications

• Automotive systems — Suitable for automotive electronics that require AEC-Q200-qualified capacitors and reliable operation to 105 °C.
• Power filtering and decoupling — Provides bulk capacitance and ripple current capability for DC bus stabilization and power supply smoothing.
• High-voltage SMD designs — 80 V rating and compact φ12.5 can form factor for space-constrained boards that need higher voltage handling.

Unique Advantages

• High voltage in a compact SMD can — 80 V rating combined with a φ12.5 × 13.5 mm package enables higher-voltage designs without a large board footprint.
• Designed for automated assembly — Embossed carrier taping and chip-type packaging simplify placement on high-volume production lines.
• Long high-temperature life — 5000-hour rating at 105 °C supports longevity in hot operating environments and reduces maintenance cycles.
• Frequency-flexible ripple performance — Specified ripple current at both 120 Hz and 10 kHz addresses low- and high-frequency filtering needs.
• Automotive-grade qualification — AEC-Q200 qualification targets applications where component-level quality and reliability traceability are required.
