GYE1V391MCW1GS

The GYE1V391MCW1GS from Nichicon is a conductive polymer hybrid aluminum electrolytic capacitor in the GYE series, designed for chip-type, high-reliability applications. It combines low ESR and high ripple-current capability with long-term endurance at elevated temperatures, making it suited to demanding electronic systems that require stable power smoothing under thermal stress.

Key Features

• Electrical Characteristics — 390 μF capacitance at a 35 V rating with ±20% tolerance; polarized design for DC filtering and energy smoothing.
• Low ESR & High Ripple Handling — ESR of 16 mΩ at 100 kHz with ripple-current ratings of 3.5 A at 100 kHz and 525 mA at 120 Hz to support high-frequency power conversion and decoupling.
• High-Temperature Endurance — Rated for operation from -55 °C to +125 °C with a specified lifetime of 4000 hours at 125 °C under rated conditions.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant, targeting applications that demand automotive-grade qualification and environmental compliance.
• Package & Mounting — Surface-mount radial can (SMD) package with compact dimensions (L: 1.25 × D: 1.00 cm) and recommended land size of 1.03 × 1.03 cm for PCB integration.
• Controlled Loss & Leakage — Specified tan δ performance (max. 0.12 at 35 V) and leakage current limited to 0.01CV (μA) after 2 minutes at 20 °C for predictable behavior in bias conditions.

Typical Applications

• Automotive electronics — Suited for automotive systems where AEC-Q200 qualification and high-temperature endurance are required.
• Surface-mount power modules — Compact SMD radial can and high ripple capability make it appropriate for power-supply modules and DC–DC converter stages.
• High-temperature electronics — Designed for boards and assemblies operating at elevated ambient temperatures up to 125 °C with long-term stability.

Unique Advantages

• Long-term high-temperature endurance: 4000 hours at 125 °C provides predictable lifetime for thermally stressed designs.
• High ripple-current capacity: 3.5 A at 100 kHz and 525 mA at 120 Hz reduce temperature rise and support higher power-density designs.
• Low ESR for high-frequency performance: 16 mΩ at 100 kHz improves efficiency and voltage stability in switching power stages.
• AEC-Q200 qualified and RoHS compliant: Enables use in regulated and qualification-driven environments while meeting environmental restrictions.
• Compact SMD form factor: Radial can SMD package and small PCB land footprint simplify assembly and save board space.
• Predictable loss and leakage behavior: Specified tan δ and leakage limits help designers model frequency-dependent losses and standby currents.
