GYF1V121MCQ1GS

The GYF1V121MCQ1GS is a conductive polymer hybrid aluminum electrolytic capacitor in a compact surface-mount can (φ6.3 × 7.7 mm). Designed for high-temperature, high-reliability applications, it delivers high capacitance with low ESR and elevated ripple-current capability.

Targeted for automotive and other demanding electronics, this AEC-Q200-qualified device offers a long endurance of 4000 hours at 125°C and RoHS compliance, making it suitable where sustained performance in harsh thermal environments is required.

Key Features

• Capacitance & Voltage — 120 µF rated at 35 V with ±20% tolerance, providing bulk energy storage in a small SMD can.
• Conductive Polymer Hybrid Dielectric — Combines the benefits of conductive polymer and aluminum electrolytic technologies for reduced loss and improved ripple handling.
• Low ESR & High Frequency Performance — 35 mΩ ESR measured at 100 kHz (20°C) and 0.12 tanδ (20°C/120 Hz), supporting stable operation under high-frequency loading.
• High Ripple Current Capability — 255 mA at 120 Hz (low-frequency) and 1.7 A at 100 kHz (high-frequency), enabling effective smoothing of switching supplies and transient currents.
• Long Endurance at Elevated Temperature — Rated for 4000 hours life at 125°C under specified conditions, with defined limits for capacitance, tanδ and ESR after endurance testing.
• Wide Operating Temperature — −55°C to +125°C category temperature range for reliable performance across harsh environments.
• Surface-Mount, Production-Ready Packaging — Radial SMD can with embossed carrier taping and mass production status to support automated assembly.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant, meeting industry requirements for automotive-grade components and environmental regulations.

Typical Applications

• Battery Management Systems (BMS) — Designed for BMS modules that demand high ripple current handling and long-term stability at elevated temperatures.
• Automotive Power Electronics — Suited for automotive electronic control units and power rails where AEC-Q200 qualification and 125°C endurance are required.
• DC–DC Converters and Power Rails — Low ESR and high-frequency ripple capability support voltage regulation and decoupling in switching power stages.

Unique Advantages

• High ripple tolerance: 1.7 A at 100 kHz and 255 mA at 120 Hz allow aggressive filtering of switching noise and transients.
• Low effective series resistance: 35 mΩ ESR at 100 kHz helps minimize power loss and thermal rise in high-current applications.
• Extended high-temperature life: 4000 hours at 125°C provides predictable long-term behavior in elevated-temperature systems.
• AEC-Q200 qualification: Confirms suitability for automotive-grade designs that require component-level reliability verification.
• Compact SMD can package: φ6.3 × 7.7 mm size with embossed carrier taping supports space-constrained layouts and automated assembly.
• Regulatory compliance: RoHS compliance supports use in regulated markets and products.
