GYB1K470MCQ1GS

The GYB1K470MCQ1GS is a conductive polymer hybrid aluminum electrolytic capacitor in a surface-mount radial can package. It provides 47 µF capacitance at 80 V with low ESR and high ripple-current capability for demanding power decoupling and filtering tasks.

Designed and qualified for automotive use (AEC-Q200) and long-term operation, this part targets automotive and other high-reliability power electronics that require low impedance, high ripple handling, and extended endurance up to 10,000 hours at 105°C.

Key Features

• Capacitance and Voltage: 47 µF nominal capacitance with ±20% tolerance and 80 V rated voltage for high-voltage power rails.
• Conductive Polymer Hybrid Construction: Hybrid polymer technology lowers ESR and improves high-frequency performance compared to standard electrolytic designs.
• Low ESR: 36 mΩ equivalent series resistance measured at 20°C/100 kHz, supporting low-loss operation in high-frequency circuits.
• High Ripple Current Capacity: 240 mA at 120 Hz (low frequency) and 1.6 A at 100 kHz (high frequency), enabling robust filtering under heavy ripple conditions.
• Leakage Current: Specified leakage current of 188 µA at rated conditions for predictable standby and bias performance.
• Long Endurance: 10,000 hours life at 105°C under rated bias and ripple conditions, with defined limits for capacitance change, tan δ, ESR, and leakage after endurance testing.
• Wide Temperature Range: Operates from −55°C to +105°C to accommodate harsh thermal environments.
• Package & Mounting: φ10 × 10 mm radial can SMD package, supplied in embossed carrier taping for automated surface-mount assembly and mass production readiness.
• Reliability & Compliance: AEC-Q200 qualified and RoHS compliant for regulated manufacturing and automotive-grade applications.
• Soldering Heat Resistance: Meets soldering heat requirements (hot plate 250°C, 30 s) as described in the series specification for robust assembly processes.

Typical Applications

• Automotive power electronics: Bulk decoupling and smoothing on high-voltage rails where AEC-Q200 qualification, low ESR, and high ripple handling are required.
• On-board DC-DC converters: Output filtering and energy buffering to support stable regulation under dynamic loads and high-frequency switching.
• Power modules and motor drives: Local decoupling in systems that demand high ripple current capability and long-term endurance at elevated temperatures.

Unique Advantages

• High-voltage capability: 80 V rating enables use on higher-voltage rails without series stacks or additional components.
• Low impedance at high frequency: 36 mΩ ESR at 100 kHz reduces voltage ripple and power loss in switching environments.
• Robust ripple performance: Combined low- and high-frequency ripple current ratings support mixed-frequency power systems and switching regulators.
• Long-term reliability: 10,000 hours endurance at 105°C under rated conditions provides predictable life for demanding applications.
• Automotive qualification: AEC-Q200 rating and RoHS compliance simplify integration into regulated automotive designs.
• Manufacturing-ready packaging: Embossed carrier taping and SMD radial can format enable automated placement and high-volume production.
