UBC1H221MNS1MS

The UBC1H221MNS1MS is a surface-mount aluminum electrolytic chip capacitor in Nichicon's UBC series, rated 220 µF at 50 V. It combines high capacitance in a compact SMD can package with engineering targeted for high-temperature and vibration-prone environments.

Designed for demanding electronics—including automotive systems and other high-temperature applications—this part delivers extended endurance (1000 hours at 150°C) and vibration resistance while remaining RoHS compliant and AEC-Q200 qualified.

Key Features

• Electrical Capacity: 220 µF nominal capacitance with a tolerance of ±20% (120 Hz, 20°C), providing bulk energy storage and smoothing for power rails.
• Rated Voltage: 50 V working voltage suitable for many power-supply and intermediate-bus applications.
• High‑Temperature Endurance: Qualified for 1000 hours at +150°C, enabling long-term operation in elevated-temperature environments.
• Temperature Range: Operational from −55°C to +150°C to cover a wide span of environmental conditions.
• Low Loss Characteristic: Tangent of loss angle (tan δ) specified at 0.12, enabling predictable AC performance in filtering applications.
• Leakage Current: Specified leakage current of 330 µA (after rated-voltage application), useful for margining power budgets and bias stability.
• Ripple Handling: Ripple current ratings include 368.5 mA at 120 Hz and 550 mA at 10 kHz, supporting both low- and high-frequency noise attenuation.
• Mechanical & Mounting: Chip-type radial can SMD, size φ16 × 16.5 mm (approximately 1.6 × 1.65 cm), surface-mount land recommended 1.63 × 1.63 cm; supplied in embossed carrier taping for automated placement.
• Reliability & Compliance: Vibration-resistant construction, RoHS compliant and AEC-Q200 rated for use in demanding electronic designs.

Typical Applications

• Automotive electronics: Bulk smoothing and decoupling in control modules and power subsystems where high temperature and vibration resistance are required.
• High-temperature power modules: Energy storage and ripple suppression on DC rails operating near elevated ambient temperatures.
• Vibration-prone equipment: Power filtering in motor drives, inverters, and ruggedized industrial electronics subjected to mechanical stress.
• Board-level power filtering: Decoupling and bulk capacitance for power supplies on compact PCBs where a compact SMD can package is needed.

Unique Advantages

• Engineered for high temperatures: 1000-hour endurance at 150°C provides design margin for sustained elevated-temperature operation.
• Compact, high-capacitance SMD can: 220 µF in a φ16 × 16.5 mm profile reduces board area compared with larger radial solutions while supporting automated assembly.
• Vibration-resistant construction: Designed to withstand mechanical stresses common in automotive and industrial environments, improving system reliability.
• Measured ripple and loss specs: Specified ripple currents at 120 Hz and 10 kHz and a low tan δ (0.12) allow predictable AC performance across frequency ranges of interest.
• Automotive-grade qualification: AEC-Q200 rating and RoHS compliance support use in regulated or safety-conscious programs.
• Production-ready packaging: Supplied in embossed carrier taping and listed as mass production status for supply-chain predictability.
