GYF1H221MCQ1GS

The GYF1H221MCQ1GS is a conductive polymer hybrid aluminum electrolytic capacitor in a surface-mount radial can package. It delivers 220 µF capacitance at 50 V with a wide operating temperature range of -55°C to 125°C and long endurance for high-reliability designs.

Designed and manufactured by Nichicon for demanding power applications, the GYF1H221MCQ1GS combines low ESR and high ripple-current capability with AEC-Q200 qualification and RoHS compliance, making it suitable for automotive and other high-stress electronic systems.

Key Features

• Conductive polymer hybrid construction — Combines the benefits of conductive polymer and aluminum electrolytic technology for improved performance in power applications.
• Capacitance and voltage — 220 µF rated capacitance with ±20% tolerance at a 50 V rating, suitable for bulk decoupling and energy storage in high-voltage subsystems.
• Low ESR — ESR of 18 mΩ measured at 20°C / 100 kHz helps reduce power loss and heat generation under switching conditions.
• High ripple-current capability — Low-frequency ripple current 450 mA (120 Hz) and high-frequency ripple current 3.0 A (100 kHz) for robust handling of pulsating loads.
• Long endurance at elevated temperature — Rated lifetime of 4000 hours at 125°C with endurance characteristics defined for capacitance, tan δ, ESR and leakage current.
• Wide temperature range — Operates from -55°C to 125°C to support harsh-environment applications.
• Leakage current — Specified leakage current of 110 µA at rated conditions for predictable bias behavior.
• Packaging and mounting — Surface-mount radial can, size φ10 × 12.5 mm, supplied on embossed carrier taping for automated assembly.
• Automotive-ready and compliant — AEC-Q200 qualification and RoHS compliance for regulated and automotive designs.

Typical Applications

• Battery management systems (BMS) — Handles high ripple currents and low ESR demands common in BMS power conditioning and filtering.
• Automotive power electronics — Bulk decoupling and smoothing for in-vehicle DC-DC converters and power modules operating across wide temperatures.
• High-ripple power rails — Suitable for power-supply output filtering where sustained ripple current and thermal endurance are required.

Unique Advantages

• High ripple tolerance: Rated 3.0 A at 100 kHz and 450 mA at 120 Hz, enabling reliable performance under pulsating loads.
• Low-loss operation: 18 mΩ ESR at 100 kHz reduces dissipation and helps control operating temperature in dense power systems.
• Extended high-temperature life: 4000 hours at 125°C provides predictable aging and longer service life in hot environments.
• Automotive-grade qualification: AEC-Q200 rating supports deployment in automotive electronics and similarly demanding applications.
• Surface-mount assembly ready: Embossed carrier taping and SMD radial can package simplify automated placement and production flow.
• Regulatory compliance: RoHS-compliant construction supports environmental and regulatory requirements.
