GYF1J121MCQ1GS

The GYF1J121MCQ1GS is a conductive polymer hybrid aluminum electrolytic capacitor in a surface-mount can package designed for high-reliability power applications. It combines low equivalent series resistance and high ripple-current capability with a long endurance rating to support demanding thermal and electrical environments.

Targeted for automotive and industrial power electronics, this part delivers 120 µF at 63 V with AEC-Q200 qualification, a wide operating temperature range of −55°C to 125°C, and 4000 hours of endurance at 125°C for stable long-term performance.

Key Features

• Core Technology - Conductive polymer hybrid aluminum electrolytic construction for low ESR and sustained capacitance under bias.
• Capacitance & Voltage - 120 µF nominal capacitance with ±20% tolerance at a 63 V rated voltage.
• Low ESR - ESR of 30 mΩ measured at 20°C/100 kHz, minimizing losses in high-frequency power stages.
• High Ripple-Current Capability - Rated for 300 mA at 120 Hz (low frequency) and 2 A at 100 kHz (high frequency) to handle both bulk and switching ripple.
• Long Endurance - 4000 hours life at 125°C under rated conditions, with defined limits on capacitance change, tan δ and ESR after endurance testing.
• Wide Temperature Range - Operates from −55°C to 125°C to support thermal extremes in harsh environments.
• Package & Assembly - φ10 × 10L (L: 1 × D: 1 cm) SMD radial/can package with embossed carrier taping suitable for automated assembly; resistance to soldering heat tested at 250°C for 30 seconds.
• Leakage & Tolerance - Specified leakage current 75.6 µA and capacitance tolerance of ±20% (at 120 Hz, 20°C).
• Standards & Compliance - AEC-Q200 qualified and RoHS compliant for regulated applications and environments.
• Production Status - Mass production available for volume designs.

Typical Applications

• Automotive power systems – Bulk filtering and decoupling in battery management systems (BMS) and power distribution modules where AEC-Q200 qualification and high-temperature endurance are required.
• DC–DC converters – Output smoothing and high-frequency ripple attenuation in switching regulators, leveraging the 30 mΩ ESR and 2 A high-frequency ripple rating.
• In-vehicle electronics & modules – Energy storage and transient suppression for ECUs, sensors, and infotainment modules operating across −55°C to 125°C.
• Industrial power electronics – High-reliability filtering in converters and power supplies exposed to elevated temperatures and sustained ripple stress.

Unique Advantages

• Low-loss performance: 30 mΩ ESR at 100 kHz reduces dissipation and voltage drop in high-frequency circuitry.
• High ripple endurance: Dual-frequency ripple ratings (300 mA at 120 Hz, 2 A at 100 kHz) allow use across both bulk-filter and switching-filter roles.
• Thermal robustness: 4000 hours at 125°C endurance backing stable capacitance and ESR retention for long life in hot environments.
• Automotive-ready: AEC-Q200 qualification supports integration into vehicle power systems and other regulated applications.
• Compact SMD can: φ10×10L form factor and embossed carrier taping enable automated placement while conserving board area.
• Regulatory compliance: RoHS conformity for use in markets requiring restricted substance compliance.
