GWC1E221MCO1GS

The GWC1E221MCO1GS is a chip-type conductive polymer hybrid aluminum electrolytic capacitor designed for high-reliability, high-temperature applications. It delivers low equivalent series resistance (ESR) and high ripple current in a compact surface-mount radial can package.

Targeted for automotive and other systems exposed to elevated temperatures, this capacitor combines a 220 µF, 25 V rating with an operating temperature range of −55 °C to 135 °C, a long rated lifetime of 4000 hours at 135 °C, and AEC-Q200 qualification for demanding designs.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 25 V and ±20% tolerance for decoupling and bulk energy storage.
• High-Temperature Endurance — Rated for operation from −55 °C to 135 °C, with a specified lifetime of 4000 hours at 135 °C.
• Low ESR — 18 mΩ ESR measured at 100 kHz (20 °C), supporting low-loss operation at high switching frequencies.
• High Ripple Current — Capable of 3 A ripple current at 100 kHz and 450 mA at 120 Hz, enabling robust handling of converter and switching noise.
• Reliability & Qualification — AEC-Q200 qualified and compliant with RoHS (2011/65/EU, (EU)2015/863); endurance and damp-heat characterizations are specified in the datasheet.
• Package & Mounting — Chip-type, surface-mount radial can (SMD) package with compact dimensions (L: 10 mm × D: 8 mm) and a recommended land pattern of 8.3 mm × 8.3 mm.
• Leakage Current — Specified leakage current after 2 minutes is not more than 0.01 × C × V (μA), per the datasheet test method.

Typical Applications

• Automotive electronics — Designed for automotive power systems and modules where AEC-Q200 qualification and high-temperature endurance are required.
• High-temperature systems — Suited for electronics that operate in elevated ambient temperatures up to 135 °C thanks to long life and temperature-rated specifications.
• Power conversion and filtering — Low ESR (18 mΩ at 100 kHz) and high ripple current capability (3 A at 100 kHz) make it appropriate for DC-DC converter outputs and switching power supplies.

Unique Advantages

• High-temperature reliability: 4000 hours of rated life at 135 °C provides predictable long-term performance in hot environments.
• Low-loss operation: 18 mΩ ESR at 100 kHz reduces heat generation and improves efficiency in high-frequency power stages.
• Robust ripple handling: 3 A ripple current capability at 100 kHz supports demanding switching applications and lowers voltage ripple.
• Automotive-ready qualification: AEC-Q200 qualification supports use in automotive-grade designs requiring industry-recognized reliability testing.
• Compact SMD form factor: Chip-type radial can package and small footprint (recommended land 8.3 mm × 8.3 mm) save board space while enabling surface-mount assembly.
• Standards compliance: RoHS compliant (2011/65/EU, (EU)2015/863) for environmental regulatory alignment.
