GYB1K470MCW1GS

The GYB1K470MCW1GS is a conductive polymer hybrid, surface-mount aluminum electrolytic capacitor from Nichicon's GYB series. It provides 47 µF capacitance at an 80 V rating in a compact φ10 × 10 mm can-style SMD package optimized for high-temperature, high-reliability environments.

Designed for demanding power applications, this component combines low ESR, high ripple-current capability and long life (10,000 hours at 105°C) to address high-voltage smoothing and decoupling needs where durability and stable electrical performance are required.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with ±20% tolerance, rated for 80 V operation.
• Low ESR — Measured equivalent series resistance of 36 mΩ at 20°C/100 kHz for reduced AC losses and improved high-frequency performance.
• High Ripple-Current Capacity — 240 mA at 120 Hz (low frequency) and 1.6 A at 100 kHz (high frequency) to handle both mains-frequency and high-frequency ripple stress.
• Low Leakage — Typical leakage current of 188 µA, supporting stable DC performance after voltage application.
• Long-Life, High-Temperature Endurance — Rated for 10,000 hours at 105°C; operating temperature range −55°C to +105°C.
• Automotive-Grade Reliability — AEC-Q200 qualified and specified with endurance, damp-heat and shelf-life characteristics appropriate for demanding applications.
• Package & Assembly — Surface-mount radial/can SMD package (φ10 × 10 mm) with embossed carrier taping and vibration-resistant construction for automated, high-volume assembly.
• Environmental Compliance — RoHS compliant.
• Polarized Device — Polarized electrolytic construction; observe correct polarity in circuit placement.

Typical Applications

• Automotive electronic power systems — Suited to automotive circuits that require 80 V rating, high ripple tolerance and long-term reliability at elevated temperatures.
• High-voltage power rails — Provides smoothing and decoupling where low ESR and high ripple-current capability reduce power losses and voltage ripple.
• High-temperature environments — Used in designs that demand stable performance across −55°C to +105°C and extended endurance (10,000 hours at 105°C).

Unique Advantages

• High-voltage capability: 80 V rating enables use on elevated DC rails without series stacking or special derating.
• Reduced AC losses: Low ESR (36 mΩ at 100 kHz) minimizes dissipation under high-frequency ripple conditions.
• Robust ripple handling: 1.6 A at 100 kHz and 240 mA at 120 Hz accommodate both HF decoupling and LF smoothing duties.
• Long-term durability: 10,000-hour life at 105°C supports extended operation in thermally stressed systems.
• Production-ready packaging: Embossed carrier taping and vibration-resistant construction streamline automated placement and yield in volume manufacturing.
• Automotive qualification and compliance: AEC-Q200 rating and RoHS compliance align the part to regulated industry requirements.
