GYF1E331MCW1GS

The GYF1E331MCW1GS is a surface-mount conductive polymer hybrid aluminum electrolytic capacitor from Nichicon’s GYF series. It delivers 330 µF capacitance at a 25 V rating with low ESR and high ripple-current capability for demanding power applications.

Designed for use across automotive and rugged electronics, this device combines a wide operating temperature range (‑55 °C to 125 °C), AEC-Q200 qualification, and a long endurance rating to support high-reliability designs where sustained high-temperature operation and ripple handling are required.

Key Features

• Core Performance 330 µF capacitance with ±20% tolerance at 120 Hz, 20 °C for bulk energy storage and decoupling.
• Low ESR and High-Frequency Performance ESR of 27 mΩ measured at 20 °C/100 kHz and high-frequency ripple current capability of 2.0 A at 100 kHz, enabling effective suppression of high-frequency ripple on power rails.
• Low-Frequency Ripple Handling Supports 300 mA ripple current at 120 Hz for bulk smoothing and low-frequency ripple applications.
• High-Temperature Endurance Rated life of 4000 hours at 125 °C under specified conditions, allowing extended operation in elevated-temperature environments.
• Wide Temperature Range Specified for operation from ‑55 °C to 125 °C to cover harsh thermal conditions.
• Compact SMD Package Chip-type can package (φ8 × 10 mm) in embossed carrier taping for automated surface-mount assembly and vibration-resistant mounting.
• Leakage and Dissipation Leakage current specified at 82.5 µA and tan δ (DF) of 0.14 at 25 V (20 °C, 120 Hz), providing predictable dissipation characteristics.
• Automotive-Grade Qualification AEC-Q200 rating and RoHS compliance support use in regulated automotive and industrial applications.

Typical Applications

• Battery Management Systems (BMS) Provides high ripple-current handling and long-term high-temperature endurance for cell balancing and power filtering in BMS modules.
• High-Ripple Power Rails Low ESR and 2.0 A HF ripple capability make this capacitor suitable for smoothing and noise suppression on DC‑DC converter outputs and power rails.
• Automotive Electronics AEC‑Q200 qualification and an operating range to 125 °C support use in automotive control units and power electronics that require robust, long-life capacitors.
• Rugged Industrial Systems Vibration-resistant SMD mounting and long high-temperature endurance suit industrial applications exposed to thermal and mechanical stress.

Unique Advantages

• High ripple tolerance: 2.0 A at 100 kHz plus 300 mA at 120 Hz allows a single component to handle both HF and LF ripple demands, simplifying BOM and layout.
• Low thermal stress footprint: Low ESR (27 mΩ) reduces I²R loss and thermal rise on power rails, improving system reliability under continuous load.
• Extended high‑temperature life: 4000 hours at 125 °C delivers predictable ageing characteristics for long-term deployments in hot environments.
• Automotive-ready qualification: AEC‑Q200 rating and RoHS compliance enable use in regulated automotive and industrial programs.
• SMD readiness: Embossed carrier taping and compact φ8 × 10 mm can package support automated assembly and vibration-resistant installation.
