GYE1C391MCQ1GS

The GYE1C391MCQ1GS is a conductive polymer hybrid aluminum electrolytic chip capacitor designed for high-reliability surface-mount power applications. It delivers a large 390 µF capacitance at a 16 V rating in a compact SMD can package.

Engineered for demanding thermal and ripple environments, this part offers low ESR, high ripple-current capability and long endurance at elevated temperatures, making it suited to automotive and high-temperature electronics applications where space and thermal performance are critical.

Key Features

• Capacitance & Voltage — 390 µF rated capacitance at 16 V with ±20% tolerance for bulk energy storage and decoupling.
• Conductive Polymer Hybrid Construction — Polymer-hybrid aluminum electrolytic architecture for improved electrical performance compared with traditional electrolytics.
• Low ESR — ESR of 25 mΩ measured at 100 kHz, 20°C, enabling lower losses and improved filtering performance at high frequency.
• High Ripple Current — Rated ripple current of 2 A at 100 kHz (and 300 mA at 120 Hz) for robust handling of switching currents.
• High-Temperature Endurance — Long life specified as 4000 hours at 125°C with defined limits on capacitance change, tan δ and ESR after endurance testing.
• Wide Operating Temperature — Specified for −55°C to +125°C operation for use in elevated-temperature environments.
• SMD Can Package — Surface-mount radial can package (chip type) with compact dimensions (L: 1.0 cm × D: 0.8 cm) and a recommended land pattern of 8.3 mm × 8.3 mm.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant.

Typical Applications

• Automotive Electronics — Suitable for in-vehicle power modules and electronic control units where AEC-Q200 qualification and extended temperature endurance are required.
• Power Conversion & Filtering — Bulk and decoupling capacitor for DC–DC converters and switching regulators that demand low ESR and high ripple-current capability.
• Compact SMD Power Modules — Fits space-constrained surface-mount designs needing high capacitance in a small can-style package and defined PCB land pattern.
• High-Temperature Industrial Electronics — Filtering and energy storage in systems that operate up to 125°C and require long life under DC bias and ripple stress.

Unique Advantages

• High energy density in a small SMD package: 390 µF in a 1.0 × 0.8 cm form factor enables significant capacitance without large board area.
• Low-frequency and high-frequency ripple handling: Specified ripple currents at both 120 Hz and 100 kHz cover a wide range of power-conversion conditions.
• Stable high-temperature performance: 4000-hour endurance at 125°C with controlled limits on capacitance change, tan δ and ESR preserves long-term performance.
• Low-loss operation at switching frequencies: 25 mΩ ESR at 100 kHz reduces dissipation and improves efficiency in switching power stages.
• Qualified for demanding environments: AEC-Q200 qualification and RoHS compliance support regulated and automotive-grade design requirements.
