GXC1E221MCQ1GS

The GXC1E221MCQ1GS is a conductive polymer hybrid aluminum electrolytic capacitor in Nichicon’s GXC series, engineered for high-reliability applications that require low ESR and high ripple-current capability. As a chip-type, surface-mount radial can, it combines a compact footprint with performance optimized for elevated temperatures.

Designed for demanding electronics—including automotive systems and other high-temperature environments—this part delivers long life and stable electrical characteristics at up to 135°C, making it suitable for power delivery and decoupling tasks where durability and thermal tolerance are required.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 25 V with ±20% tolerance for bulk energy storage and smoothing on intermediate power rails.
• Low ESR — 18 mΩ equivalent series resistance at 100 kHz (20°C), supporting low-loss operation and improved efficiency in high-frequency circuits.
• High Ripple Current — 420 mA at 120 Hz and 2.8 A at 100 kHz, enabling effective handling of AC ripple on power converters and switching regulators.
• High-Temperature Endurance — Rated for continuous operation from –55°C to +135°C with a specified lifetime of 4000 hours at 135°C, providing stability in thermally challenging environments.
• Robust Packaging — Surface-mount radial can (chip-type) with compact dimensions (L: 1.0 × D: 0.8 cm) and recommended PCB land size of 8.3 × 8.3 mm for space-efficient layout.
• Automotive-Grade Qualification — AEC-Q200 qualified and RoHS compliant, suitable for designs that require automotive-level reliability and regulatory conformance.

Typical Applications

• Automotive power systems — Bulk smoothing and decoupling on high-temperature vehicle power rails where AEC-Q200 qualification and thermal endurance are required.
• Power converters and regulators — Output filtering and ripple suppression in DC‑DC converters and switching regulators that demand low ESR and high ripple-current capability.
• High-temperature electronics — Energy storage and decoupling in electronics exposed to elevated ambient temperatures up to 135°C, maintaining capacitance and ESR stability over long life.

Unique Advantages

• Proven high-temperature endurance: 4000 hours at 135°C life rating provides predictable aging and long-term performance in heat-stressed designs.
• Low-loss operation: 18 mΩ ESR at 100 kHz reduces power dissipation and supports efficient power-stage operation at high switching frequencies.
• High ripple handling: Rated ripple currents of 420 mA (120 Hz) and 2.8 A (100 kHz) allow the capacitor to absorb switching ripple without excessive heating.
• Automotive-level reliability: AEC-Q200 qualification and RoHS compliance give confidence for use in automotive modules and regulated environments.
• Compact SMD form factor: Chip-type, surface-mount radial can minimizes board area while providing robust electrolytic capacitance for power-dense designs.
