GYF1V121MCW1GS

The GYF1V121MCW1GS is a conductive polymer hybrid aluminum solid electrolytic capacitor in a compact surface-mount can package. It combines low ESR and high ripple-current capability with long-term endurance for high-temperature applications.

Designed for demanding power-management tasks, this part addresses high-ripple, high-temperature environments commonly found in automotive electronics and battery systems, delivering stable capacitance and low leakage over extended service life.

Key Features

• Capacitance & Voltage — 120 µF rated at 35 V with ±20% tolerance, suitable for bulk decoupling and energy buffering in medium-voltage power rails.
• Low ESR — ESR of 35 mΩ measured at 20 °C/100 kHz, enabling lower losses and improved heat performance in high-frequency circuits.
• High Ripple Current — Low-frequency ripple current 255 mA (120 Hz) and high-frequency ripple current 1.7 A (100 kHz) for reliable operation under continuous ripple stress.
• Long Life at Elevated Temperature — Endurance rated for 4000 hours at 125 °C under rated conditions, supporting extended operation in hot environments.
• Wide Temperature Range — Operating from −55 °C to +125 °C to accommodate harsh thermal conditions.
• Compact SMD Can — Size φ6.3 × 7.7 mm (L × D) with surface-mount embossed carrier taping for automated placement.
• Low Leakage — Leakage current specified at 42 µA, maintaining system efficiency and reducing standby losses.
• AEC-Q200 Qualified & RoHS Compliant — Meets AEC-Q200 reliability screening and RoHS environmental requirements for regulated applications.

Typical Applications

• Automotive Electronics — Suitable for power smoothing, decoupling and energy buffering in control modules where AEC-Q200 qualification is required.
• Battery Management Systems (BMS) — Designed for high ripple and low ESR needs in BMS circuits, supporting stable filtering and charge/discharge smoothing.
• Power Supply Filtering — Effective for bulk decoupling and output filtering in DC‑DC converters and regulator outputs operating at elevated temperatures and frequencies.

Unique Advantages

• High ripple-current capability: Rated ripple currents of 255 mA (120 Hz) and 1.7 A (100 kHz) reduce temperature rise and extend system reliability in ripple-heavy circuits.
• Low ESR for improved efficiency: 35 mΩ ESR at 100 kHz minimizes conduction losses and supports tighter voltage regulation under dynamic load.
• Extended high-temperature life: 4000 hours at 125 °C provides design margin for long-term operation in thermally demanding environments.
• Compact, assembly-friendly package: SMD radial can in embossed carrier taping eases pick-and-place integration while conserving board area.
• Automotive-grade reliability: AEC-Q200 qualification supports use in automotive systems where component-level reliability is required.
• Regulatory compliance: RoHS conformity ensures adherence to environmental requirements.
