GYF1H221MCW1GS

The GYF1H221MCW1GS is a conductive polymer hybrid aluminum electrolytic capacitor in a surface-mount can package, rated 220 µF at 50 V. It combines low equivalent series resistance and high ripple current capability with long life and wide operating temperature for demanding electronic environments.

Designed for automotive and power-management applications, this GYF-series part delivers low ESR and high-frequency performance for ripple filtering and energy buffering while meeting AEC‑Q200 qualification and RoHS compliance.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with ±20% tolerance, rated for 50 V operation.
• Low ESR — ESR of 18 mΩ measured at 20°C and 100 kHz, enabling low-loss performance in high-frequency circuits.
• High Ripple Current — Low-frequency ripple current 450 mA (120 Hz) and high-frequency ripple current 3.0 A (100 kHz) for effective AC filtering and decoupling.
• Long Endurance — 4000 hours life at 125°C under rated conditions, with post-test limits specified for capacitance, tan δ and ESR.
• Wide Temperature Range — Operates from −55°C to +125°C, supporting harsh-temperature applications.
• Surface-Mount, Compact Can — Radial can SMD package; size φ10 × 12.5 mm (L: 1.25 × D: 1.00 cm) for space-efficient board integration.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant; designed with vibration resistance for robust field performance.
• Low Leakage — Specified leakage current of 110 µA, supporting stable bias conditions after application of rated voltage.

Typical Applications

• Battery Management Systems (BMS) — High ripple capability and low ESR suit filtering and energy buffering in BMS modules, as indicated for the GYF series.
• Automotive Power Electronics — AEC‑Q200 qualification, wide temperature range, vibration resistance and long endurance make this capacitor suitable for in-vehicle power modules and control units.
• High-Ripple Filtering and Decoupling — Low ESR and 3.0 A high-frequency ripple rating enable effective smoothing and decoupling in power converters and DC supply lines.

Unique Advantages

• Durable under high temperature: 4000 hours rated life at 125°C provides predictable long-term behavior in elevated-temperature environments.
• Efficient high-frequency performance: 18 mΩ ESR at 100 kHz and a 3.0 A high-frequency ripple rating reduce losses and improve power-stage stability.
• Automotive-capable design: AEC‑Q200 qualification and vibration resistance address automotive reliability requirements.
• Wide operating range: −55°C to +125°C operation supports both cold-start and high-heat conditions encountered in vehicle and industrial applications.
• Compact SMD can package: φ10 × 12.5 mm can format provides a high-capacity, surface-mount solution for space-constrained boards.
• Standards and environmental compliance: RoHS conformity ensures adherence to environmental directives for electronics manufacturing.
