The GWC1H221MNU1GS is a conductive polymer hybrid aluminum solid electrolytic capacitor from Nichicon’s GWC series. It combines low ESR and high ripple-current capability with a polarized, surface-mount radial can package optimized for compact, high-temperature designs.

Designed for demanding environments, the component targets applications that require elevated temperature endurance and long operational life, while meeting industry compliance and reliability requirements.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Conductive Polymer Hybrid Construction — Solid electrolytic hybrid design delivering low impedance and stable performance across frequency.
• Low ESR — 13 mΩ ESR measured at 100 kHz (20°C), supporting efficient power delivery in ripple-prone circuits.
• High Ripple Current — Rated ripple handling of 570 mA at 120 Hz and 3.8 A at 100 kHz, suitable for high-ripple power stages.
• High-Temperature Endurance — Operating range from −55°C to 135°C with long life specified as 4000 hours at 135°C.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863) for regulated and automotive applications.
• Package & Mounting — Surface-mount radial can (SMD) package; compact footprint with body dimensions L 1.65 × D 1.00 cm and recommended land size L 1.03 × W 1.03 cm. Polarized component.
• Leakage Current Specification — Leakage current meets the series standard of not more than 0.01CV (µA) after 2 minutes at 20°C and rated voltage.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and high-temperature endurance make this capacitor suitable for vehicle electronic modules that demand reliability under thermal stress.
• High-Ripple Power Stages — Low ESR and multi-ampere high-frequency ripple ratings support DC‑DC converters and power-supply filtering where ripple handling is critical.
• High-Temperature Electronics — Rated operation to 135°C and a 4000-hour life at that temperature support assemblies exposed to elevated ambient or localized heating.
• Compact SMD Power Designs — Radial can SMD packaging and a small footprint enable space-efficient board layouts for compact power modules.

Unique Advantages

• Low ESR for improved efficiency: 13 mΩ at 100 kHz reduces loss and voltage ripple in high-frequency power circuits.
• High ripple tolerance: 3.8 A at 100 kHz (and 570 mA at 120 Hz) lets designs tolerate heavier ripple currents without premature degradation.
• Extended high-temperature life: Specified 4000 hours at 135°C provides predictable longevity in thermally demanding deployments.
• Automotive-grade reliability: AEC-Q200 qualification aligns the part with automotive quality requirements for electronic modules.
• Compact SMD radial can: Small L × D footprint and defined land pattern simplify PCB integration in space-constrained designs.
• Regulatory compliance: RoHS compliance ensures suitability for regulated markets and assemblies.
