UCM1H221MNS1GS

The UCM1H221MNS1GS from Nichicon is a chip‑type, low‑impedance aluminum electrolytic capacitor in a surface‑mount can package. It provides 220 µF capacitance at a 50 V rating with a compact φ8 × 10 mm footprint and embossed carrier taping for automated placement.

Designed for demanding environments, this part offers AEC‑Q200 qualification, vibration resistance, a wide operating temperature range of −55 °C to +105 °C, and an endurance rating of 2000 hours at 105 °C, making it suitable for robust system power designs.

Key Features

• Capacitance & tolerance — 220 µF with ±20% tolerance (measured at 120 Hz, 20 °C).
• Rated voltage — 50 V nominal rating for higher-voltage power rails and systems.
• Low impedance performance — Chip‑type, low‑impedance construction with tanδ of 0.10 (120 Hz, 20 °C) for stable AC behavior.
• Ripple current handling — 335 mA at 120 Hz (low frequency) and 670 mA at 10 kHz (high frequency) for effective ripple filtering in power supplies.
• Leakage current — Typical leakage current of 110 µA after 2 minutes at rated voltage and 20 °C.
• Thermal and endurance — Operates from −55 °C to +105 °C with a life/endurance of 2000 hours at 105 °C.
• Robust packaging — Surface mount, radial can (SMD) package (φ8 × 10 mm) with embossed carrier taping for automated assembly; surface mount land size 8.3 × 8.3 mm.
• Reliability & compliance — AEC‑Q200 qualified and RoHS compliant; vibration resistant construction for mechanically demanding environments.

Typical Applications

• Automotive electronic modules — Supports vehicle electronics that require AEC‑Q200 qualification, wide temperature range, and vibration resistance.
• Automotive power supply filtering — 220 µF capacitance with specified ripple current (335 mA at 120 Hz, 670 mA at 10 kHz) helps stabilize and filter 50 V power rails.
• Vibration-prone environments — Vibration resistant chip construction and durable endurance make it suitable for electronics exposed to mechanical stress.

Unique Advantages

• AEC‑Q200 qualification: Enables use in applications requiring automotive-grade component reliability.
• High temperature endurance: Rated for operation to +105 °C with a 2000‑hour endurance specification, supporting long-term performance in elevated temperatures.
• Balanced ripple performance: Specified ripple currents at both low and high frequencies address filtering needs across power conversion stages.
• Low loss angle (tanδ): 0.10 at 50 V (120 Hz, 20 °C) indicating controlled AC losses for stable performance in AC and ripple conditions.
• Production-ready packaging: Embossed carrier taping supports automated surface-mount assembly and high-volume manufacturing flows.
• Compact SMD can: φ8 × 10 mm package offers high capacitance density in a small footprint for space-constrained designs.
