GYF1C122MCQ1GS

The GYF1C122MCQ1GS is a conductive polymer hybrid aluminum electrolytic capacitor in a surface-mount can package designed for high-reliability power applications. It combines high capacitance (1.2 mF) and low ESR to support heavy ripple workloads while meeting long-life requirements.

Targeted at demanding environments, this AEC-Q200–rated component delivers sustained performance across −55°C to 125°C with a rated voltage of 16 V, making it suitable for systems that require low-loss energy storage and stable filtering under elevated temperature and ripple stress.

Key Features

• Capacitance & Voltage — 1200 µF nominal capacitance with a rated voltage of 16 V and ±20% tolerance for bulk energy storage and decoupling.
• Conductive Polymer Hybrid Construction — Polymer-hybrid chemistry for improved ripple handling and reduced loss compared with traditional wet electrolytics.
• Low ESR — ESR of 15 mΩ measured at 20°C / 100 kHz to minimize heat generation and voltage drop in high-frequency power stages.
• High Ripple Current Capability — Low-frequency ripple current of 525 mA (120 Hz) and high-frequency ripple current of 3.5 A (100 kHz) for demanding smoothing and converter applications.
• High-Temperature Endurance — Rated for 4000 hours at 125°C under specified conditions, supporting long operational life in elevated-temperature environments.
• Electrical Loss Characteristic — tan δ (DF) ≤ 0.16 at 20°C and 120 Hz for the 16 V rating, aiding low-loss operation in AC ripple environments.
• Leakage Current — Specified leakage current of 192 µA after rated voltage application, useful for predicting standby power and biasing behavior.
• Package & Mounting — Surface-mount radial can (φ10 × 12.5 mm; L: 1.25 × D: 1.0 cm) supplied on embossed carrier taping for mass-production SMT assembly.
• Compliance — RoHS compliant and AEC-Q200 qualified for high-reliability applications.

Typical Applications

• Battery Management Systems (BMS) — Energy buffering and ripple absorption where high ripple current tolerance and high-temperature endurance are required.
• DC–DC Converters and Power Rails — Output smoothing and decoupling in converters that demand low ESR and high-frequency ripple handling.
• Automotive Electronics — Power smoothing and transient suppression in modules designed for the automotive environment, supported by AEC-Q200 qualification and a wide operating temperature range.
• Industrial Power Electronics — Bulk storage and filtering in industrial converters and control systems operating under elevated temperature and continuous ripple stress.

Unique Advantages

• Long High-Temperature Lifetime: 4000 hours at 125°C provides predictable end-of-life behavior for designs exposed to prolonged high temperatures.
• High Ripple Endurance: Combined low-frequency and high-frequency ripple current ratings (525 mA @120 Hz, 3.5 A @100 kHz) enable reliable operation in converters and switching power supplies.
• Low Losses at High Frequency: 15 mΩ ESR at 100 kHz and tan δ ≤ 0.16 help reduce heat and improve efficiency in high-speed power stages.
• Automotive-Grade Qualification: AEC-Q200 rating supports adoption in automotive and other high-reliability systems requiring industry-recognized qualification.
• Production-Ready Packaging: Embossed carrier taping and SMD can package facilitate automated placement and high-volume assembly.
• Regulatory Compliance: RoHS compliance for use in modern manufacturing and supply chains.
