GYC1C471MCQ1GS

The GYC1C471MCQ1GS is a surface-mount conductive polymer hybrid aluminum electrolytic capacitor designed for high-reliability, high-temperature applications. Built on Nichicon's GYC series architecture, it combines low ESR and high ripple-current capability with long-term endurance at elevated temperatures.

This part is targeted at demanding power-electronics environments — notably automotive designs — where compact surface-mount bulk capacitance, low loss, and extended life at up to 135°C are required.

Key Features

• Core Technology  Conductive polymer hybrid aluminum electrolytic construction for stable capacitance and improved high-frequency performance.
• Capacitance & Voltage  470 µF rated capacitance with a 16 V rated voltage and capacitance tolerance of −20% to +20%.
• Low Loss / Low ESR  tanδ (DF) of 0.16 measured at 20°C, 120 Hz and ESR of 20 mΩ at 100 kHz (20°C) for efficient AC performance.
• High Ripple Current Capability  315 mA at 120 Hz (low frequency) and 2.1 A at 100 kHz (high frequency) to support power-rail smoothing and switching converter loads.
• High-Temperature Endurance  Rated for operation from −55°C to +135°C with an endurance specification of 4000 hours at 135°C.
• Surface-Mount Package  Compact SMD can, size φ10 × 10 mm length, supplied in embossed carrier taping for automated assembly.
• Automotive-Grade Reliability  AEC-Q200 rating and RoHS compliance for regulated production environments.

Typical Applications

• Automotive power rails  Bulk decoupling and smoothing for ECUs and power modules where high temperature endurance and AEC-Q200 qualification are required.
• DC–DC converters  Output filtering and energy buffering in switching converters benefiting from low ESR and high ripple-current capability.
• On-board power management  Local bulk capacitance for infotainment, telematics, and control modules operating across wide temperature ranges.

Unique Advantages

• High-temperature endurance: 4000 hours at 135°C supports long-term reliability under elevated ambient conditions.
• Low ESR at high frequency: 20 mΩ at 100 kHz reduces power loss and improves filter performance in high-switching-frequency supplies.
• Strong ripple handling: 2.1 A at 100 kHz and 315 mA at 120 Hz accommodate both high-frequency switching and low-frequency ripple environments.
• Compact SMD form factor: φ10 × 10 mm can in embossed carrier taping enables automated surface-mount assembly and space-efficient board layouts.
• AEC-Q200 qualified and RoHS compliant: Meets automotive-grade and environmental requirements for regulated production systems.
• Predictable loss characteristics: tanδ 0.16 (20°C, 120 Hz) provides defined dissipation behavior for thermal and circuit design.
